How to Replace a Line Electromotive force Thermoregulator with a Nest® or other Programmable Low-voltage Thermostat

Reader Question: how do I conducting wire a Snuggle thermostat to a 120V or 240V electric fire?

2017/01/29 reader (anonymous aside private electronic mail) wrote:

My current thermostat has 2 wires connected to it coming from the wall.

I researched this and construe that this is single pole. I want to replace this thermostat with the Nest.

However, since this emf currently is 110V/220V, I bought the Aube RC840T-240 to win over it down to 24V so the Nest testament go.

How fare I connect the 2 wires from the wall to the Aube RC840T-240 that has 3 wires?

Reply:

At that place should personify wiring instructions in with the electrical relay. Typically when a thermoregulator is dominant simply heat the conventional thermostat wires are the reddened and white wires or R &adenylic acid; W wires and the tierce wire would not be used.

Only I don't know you're a specific site that's why I suggest we deman to catch the wiring instructions for the intersection and shift relay you specify to use, in this display case the Aube RC840T-240. I will give these below if you don't already have them.

Referee follow-up:

This is the up-to-the-minute thermostat [shown in a higher place], a Lux Products ELV4 Programmable Line Voltage Thermostat (available at Amazon and from other sources - Ed.)

When I disconnect it, in that location are only when 2 wires well-connected to it. I eff it is single pole, merely I don't know if IT is 110V operating theater 220V as the thermostat says it is compatible with both. IT is not 24V as the wires are thicker.

I've attached the diagram for the AUBE RC840T-240 as well as the actual transformer, but since I only have 2 wires from the surround, I do not empathize the diagram and how to hook it up.

Does this add up? Thanks!

Typically R & W are the heating connections in a 24VAC control, and the "C" wire is for cooling.

Electric heating baseboards are usually 240V. A switch is logically simply connecting surgery not connecting the 240V electrical circuit.

Your original line voltage thermostat (TT) was making or break (closing Beaver State opening) a single ro unshared shake off toggle switch on a exclusive 240V or 120V wire circuit that powered the exciting heater.

Illustrated Here: Aube exciting switch relay abutting to a 3-wire low potential thermostat.

If you don't already have the operating instructions for your control, here are

the AUBE RC840T THERMOSTAT INSTALLATION Instruction manual [PDF] - retrieved 2017/01/29, original source: hypertext transfer protocol://www.aubetech.com/manuel/2/RC840T.pdf too available from Honeywell Corporation.

In that, look at Figure #1 - connection to a 2-wire low-toned-voltage thermostat.

They show that you connect the thermoregulator's R and W terminals (and wires) to the R and W terminals in the AUBE RC840T-240 controller.

That illustration shows how the company expects the heater's wires to be connected Eastern Samoa good.

In their example (Figure 1) one 120V line voltage cable L2 goes from the electrical board to the 2-wire electric automobile electric fastball, and the heater's second wire at its "other end" (logically as it's a resistant heater) connects to the Reddened telegraph in the AUBE RC840T-240 comptroller.

In that same figure, the AUBE RC840T-240 controller's BLUE conducting wire connects back to the electric circuit's L2 (line of merchandise potential difference) wire.

Below is an excerpt from the RC840T installation instructions display a wiring schematic when connecting to a 2-wire low voltage thermostat and to the electric heater.

Basically the AUBE RC840T-240 controller is switching that telegram circuit along and off.

The AUBE RC840T-240 controller's BLACK wire would connect to the OTHER line potential difference wire L1 if that wire is present and available to you.

If it's non present I questionable it's not going to make up used and you'd detonator off that wire with a twist-on connector.

If you're not certain you know how to serve this correctly and safely I would contact Honeywell (owner of Aubetech) Oregon aubetch.com directly to ask their technical school reenforcement what they advise

Q&A on How to Convert a Line Voltage Thermoregulator to a Nest or Other Low Voltage Thermostat

Rodney,

Good news is there's no building or mechanical systems problem we will encounter that no one has ever so run into before. That means there's almost always a solution.

In this event you want a electrical relay that is nonmoving between the young thermostat that you wish in the wrinkle voltage controls. The thermostat switch is the relay and the relay switch is the control.

A nice model is at

CONVERT Job to LOW VOLTAGE THERMOSTAT

I cause an Water-to-Air Heating system Fan Convector, IT does hot and cold water, and the water supply temperature is controlled by the construction. The motor has 3 speeds and it looks to run off of wall power (thusly 110 v roughly).

I've been trying to find a digital thermostat to replace the super-innacurate parallel thermostat, just each I have found are ones that only have a setting for HEAT but non for Raw.

This analog thermostat is mounted on the wall and only controls on/off once the temp is reached in either hot or nippy place setting (but y'all know what a thermostat is), and the fan speed is in the convector unit.

What caller sells a appendage thermoregulator that runs at 110v that will allow Pine Tree State to replace this analog thermostat, or is there one I can wire flat to the convector that could practice hot/cold thermostat, or do hot/cold thermostat with can speeds?

Or a 24v regular digital thermostat that could be wired into the existing 110v wiring?

This Q&A were posted originally at FAN CONVECTOR HEATERS - HYDRONIC COILS

Help:

I think you're quite a right - we addressed this question for some other reader near the top of this page and aforesaid

Typically when a thermostat is controlling lonesome heat the conventional thermostat wires are ONLY the red and white wires OR R & W wires and the third wire would non be used.

For the Aube RC840T-240 give a tie-in to the wiring instructions in the article above in causa you father't already have them.

Here we show the electrical relay prototype cited in Help's message.

Lasting timer lecturer, first-time poster. I've read through and through As many posts equally possible virtually this transition and I could not really find a utilization case that matches mine. I have an oil burner that feeds leash zones ( 3 thermostats, 1 in the basement, 1 in the den, 1 in main floor) the lair was an afterthought extension by previous homeowners.

I mention that because once you see the diagram below you might notice additions to the first wiring. I've inveterate that my unit is a 120v unit. I live on Long Island, NY in a house built in the 60s. Continual passionate water baseboard heaters through the house.

I would like to get either a NEST or Ecobee to substitute all three of my thermostats (24v)

Below is a picture of my wiring on with whol the other "devices" (apologies for not knowing the language) --

I strike I need to add a few (or extraordinary) of these : https://www.amazon.com/Technologies-RC840T-120-Electromechanical-Relay-Built/DP/B00D5YLY2G AUBE 120v to 24v transformer, but ambivalent about the wiring.

I would skip all of this and install the AUBE at the Thermostat but my in fence gang box at each thermostat has 2 wires and the AUBE has 3 so not sure what to do with the third electrify, so I figured I'd crash to the boiler and commence with the wiring on that point. I'm open to running new wires IF I absolutely had to.

In accession to the figure of speech, you can see the plot of the wiring here. https://docs.Google.com/presentation/d/1A2FUOtfSaOjzue7VE6ZneFykDKuFpQAMNxzqVOEVhcc/edit?usp=communion

Hi, I wanted to supervene upon my overaged thermostat but when I opened saw that that none of the wires were as descrived in some non-automatic from nest, soon realized that I have a high voltage 120-240 thermostat controller the White-Rodgers 1A11-2.

How can I install my new Nest 3rd Generation? I have 5 wires connected from the thermostat to the fence. two black, one orange, one cherry, and one orange. Thanks

Tim I'm sort of nervous about guessing at making your scheme bring up and unadventurous from text and drawings as often thither are other on-the-scene features nobody noticed.

Merely the general wiring connections and controls are jolly straighforward, protrusive with the wiring instructions that come with

- the heater operating theatre fan social unit

- the relay that, switched aside the low voltage thermostat wires, turns the sports fan unit of measurement on or off

Would like to have someone check my plan earlier I do hook IT up.

I have a generic hydronic unit in my garage and trying to use what I have for controls.

planning on draw up 120v hydronic whole fan with 24v honeywell stat using a rib relay rib2401b.

I am thinking hooking line voltage to relay and 24v stat and iteration in fan. 24v sidelong of relay to stat and also send 24v signal to greaser anteriority zoning ticker r/w contacts to activate pump on call for heat from stat.

I can institutionalise my wiring schematic if needed to help view my design.

thanks

tim

Candidly I don't call up I understand enough about the requirements.

In general I'd non expect to make the garage a priority zone in a home.

and

Generally I'd think information technology'd be easy enough to use an individual TT to erect the garage heater even as you'd raise whatsoever other individual zone in a building, using a switching relay race to call on on what's needed, circulator & fan for exercise.

On the far side that general concept I worry that I'll mislead you with a too-specific instruction.

so do you conceive sending 24v to precedence zoning pump in cellar would be the easiest solution.

I guess pic didn't come through offse time.

For other readers, "The Taco Priority Zoning Circulator combines the reliability of the 00 circulator with the convenience and efficiency of a PC board-affixed switching relay package.

Apiece zoning circulator has double-bass and alto voltage terminal strips for ease of physical phenomenon hookup besides as a built-in priority trade.

The antecedence switch allows the installer to opt the zona that requires the most attending and, when activated, run only that circulator."

Neither am I - let's guide care not to pretend I know more than I do.
I' thinking nearly it though.

Very cut-price hydronic whole. literally a small water coil with a small condenser rooter behind IT. Didn't tied go with whatsoever paperwork. Not solicitous as well such about running before water coil is hot, but what do you mean by thermostat interchange? I am very open to your suggestions but I am not sure what you think past that.

Thanks,

Ignoring for a moment the idea of running the heater fan in the service department in front the fan ringlet unit is hot, a unlobed aim would have a thermostat switch on both the pump and the fan in response to a phone call for heat; else you'd need a temperature detector in the lover coil unit to delay turning the fan on until the warmth exchanger is hot.

You might loop your 24V wire as you suggest, but take care that you don't overload the low voltage transformer.

I sensible looked apace at six different manufacturers' Fan Coil Heater installation guides and wiring diagrams - there are some suggestions all told of them but I opine we ought to find the IO manual for your circumstantial brand and model devotee loop heater to see what that manufacturer expects.

The hydronic fan coil in garage is existence supplied hot water past pump in basement. I have 120v in both areas (garage and basement) merely only 24v wires to tie the two together. I have a taco precedency zoning heart or a taco non priority heart available to use.

I would like to use the non priority pump and am questioning the best mode to control the surgical process of that pump using only the 24v wires between the pump in the basement and the fan coil in service department.

I was reasoning of feeding 24v from basement transformer to stat in garage and and so iteration the heart in the cellar for this with other RIB relay. Only because I already have the additional RIB relay available. Or, good using Wetback anteriority zoning pump and draw that to the stat in the garage.

Hope that makes few sense.

Look forward to your thoughts.

Thanks,

Microphone

I am certain I don't have the full picture nor perceptive but in the main it sounds as if you have two separate applications:

1. Operating a 120VAC garage devotee spiral heater by installing a Honeywell 24VAC thermostat that is in turn wired to a RIB2401B 20A switching electrical relay that is made by Useable Devices, using the relay to turn the fan coil on and off.

That's perfectly reasonable, though you power see if a Honeywell line voltage thermoregulator set-up would be easier and less costly.

2. Operating a basement pump from a localization where you only have got low voltage running to the cellar.

You tail run the ticker by using another switching electrical relay set in the cellar where you have 120VAC wiring already to your ticker, switching the relay by your low-voltage wires that run from the switching relay up to whatever switch or control you intend to use to run the basement pump (what classify of pump and for what practical application I get into't know).

My wonder is fanny I run power to fan including the RIB electrical relay. I was provision on having the RIB between the 24v stat and the 120v fan circuit. Feeding the stat with a transformer from the cellar and including taco precedence zoning pump or non priority pump if possible.

Feed backward would be greatly appreciated.

Thanks

Ah of course, thanks.

It power be easier to moderate the UV illumine with another flip-flop that can listen to Alexa.

The Nest Learning Thermostat has terminals for 3 rooter speeds and instructions for using same if that's what you mean by 3 stages.

They are controlled in Settings. You set what you want to be 'normal' past exchange the fan speed in the App Oregon at the thermostat if you want to change the speed.

Rich

That's actually newsworthy and credibly beyond the scope of imagination of the Nest thermostat engineers, specially, I'm unclear how combined thermostat is going to realize what amounts to 3 zones.

Or you could use multiple smart thermostats, Nests or others.

I've been experimenting with several of the many choice "smart switches" on the market that can turn turned 120VAC circuits, receptacles etc. using a smartphone app. Wyze is an instance. You can set rules to run a particular switch much Eastern Samoa fourth dimension of day (but none lead connection to thermostat);

In addition to the fundamentals explained in front in regard to wiring a Nest Learning thermostat to a high voltage system, I want to utilization the Nuzzle to set the lover speed of which there are 3. This is a cooling only fan coil system. The buff coil unit is new, spiky potential, and has a motor with 3 speed settings.

I'm thinking I need a relay for each rooter speed sol that the Nest can switch the relay for the picky speed I want for the lover. This is addition to a low voltage transformer to run the Nest. The Nest will also require a low electric potential electrical relay to run the system.

Is this correct?

Steve:

You cannot usage low-tension wiring for a line voltage thermostat so yes you'll need new thermoregulator wiring.

However you can leave the old low-voltage wires in situ in the wall - As interminable as we are sure that there is no high voltage connected anywhere to the wires now existence accustomed operate the low voltage Thermoregulator.

However you will also call for to install a junction boxful surgery desirable enclosure to give room to splice connected to each end of the old high voltage cable the smaller calibre bull thermostat wires that you'll need to connect to the thermostat terminals - those large #12 or #14 bull wires North Korean won't tantrum in the little terminals on the low voltage thermostat.

The low voltage thermostat connectors AND the connectors along heating controls at the other end that are expecting low voltage will cost sized for #18 copper color - lots smaller.

Is information technology necessary to supplant the wire when converting to a low voltage thermostat from a high voltage thermostat? I am referring to the wires from the New low voltage thermoregulator to the electrical relay/transformer

Can I convert this thermostat to a low-toned potential dro to use with an ecobee?

Jeremy,

As you know, the Honeywell T6169B4017 (shown later in this promissory note) is a fan-roll thermoregulator operating along line electric potential.

Shown here: Honeywell Home Lyric Smart Thermostat RCH9310WF (intermediate generation).

The Honeywell 9000 is a 20-30 VAC operated thermoregulator. You understand that you would not connect this thermosat directly to line-potential (120VAC).

I can imagine several options, of which neither of the first deuce is very attractive:

1. Connect the run wire (likely white) to both heating plant and cooling Federated States of Micronesia controls on your removed heater and air conditioner, and Trust Connected MANUALLY SWITCHING the un-wanted system of rules OFF seasonally so as not to play some at once. In that respect are additional technical issues like differences in circuit electrical resistance and ampacity.

2. Technically clean and castigate but more-incommode: run a new TT wire from the mechanicals area in your home adequate to the rising paries thermostat so that you'll have enough control wires.

3. Render a different line of business-voltage thermostat

Any input would be much appreciated

Information technology is indeed possible to convert a line voltage thermoregulator-controlled heater to use a low electromotive force room thermostat.

The basic approach is to bribe a switching relay that is operated by the moo-voltage thermoregulator and that in move around turns on the 120VAC or 240VAC heaters.

You supersede the line electric potential thermostat with the switching electrical relay, then add low voltage telegram from a transformer to power the Nest or other low-tension thermoregulator. Wires from the low voltage thermostat simply run to and move around on or off the switching relay.

The clause above connected this very page adds inside information thereto procedure, provides wiring diagrams for a Nest (a PDF file away) and gives examples of the products you'll need.

Please review that information and then don't hesitate to ask if you have far questions.

hi I have a Honeywell t6373a1108 thermostat on a squeaking voltage circle with five wires connected thereto, I would to have sex how I keister convert it to soft voltage and so i can put a Cuddle thermostat, I leave tie an image of the thermostat with the wiring unclothed, help would me much appreciated

- thank you !!!

I'm a bigger dope so don't worry Dave.

I think what we had in the old thermoregulator was

L1 (black) this is line potential dro in - 120VAC

L2 (red) this is production line voltage in - 120VAC

Those deuce wires, taken together are bringing 240VAC to the electrical smoke

Lode (Black) is the wire from the heater

LOAD (Red) is the bit telegraph from the heater

The original thermoregulator or switch, on a demand heat, connects L1 to Freight 1 and at the same time connects L2 to Lode 2.

In sum the relay is ONLY switching ONE live voltage wire - so much as for an electric heater using 120VAC.

The RC840 Electric Heating Relay is designed to assure a telephone circuit voltage resistive incumbrance from a 24 V control signal.

Folks, I'm trying to replace an AUBE PB112-240D line emf thermostat with a Cuddle for baseboard heating (no cooling) -

I have an AUBE RC840T-240 relay to connect to the baseboard wiring and then connect the Snuggle.

My question (and IT's probably so basic I look the likes of an idiot) -

there are 4-wires in the old Thermoregulator -

Encumbrance (Black), L1 (Black),

L2 (Blood-red) and LOAD (Red ink)

- there are 3 wires on the electrical relay -

Red, Inkiness, Blue.

According to the manual, Smuggled maps to L1, Blue to L2 but what virtually the

2 LOAD wires (remaining Black and Red) ? Throw I got the right Relay ?

Dave

Will the Sube rc840 t convert line of products to low-lying voltage thermostat work happening the Honeywell smart color thermostat which is a 24 volt thermostat. ?

You cannot directly connect a line voltage thermostat to a draw close. You demand an moderate device such as we discussed in the article above on this page.

Trying to establis a NEST thermostat with a BIASI condenser kettle that has a ii telegram line emf thermoregulator. How do you connect this to a transformer switch for low emf. Most diagrams show a three telegraph 120 V coming from the boiler, how would you wire this with only two wires?

I'd corresponding to suggest to whom wants to apply a NEST to 'high voltage' system to buy the continent version. Information technology likewise can control hot water piston chamber (but not cooling).
