Do i need the jumper wire in place?
Ok so now with just one wire white and one grey what letter are these suppose to be connected to? W Y G A or R/H R/C?

Best answer:

Answer by gizmoe
I assume your talking about the RH and RC jumper.
RH is the power for heating and RC is the power for cooling.
For heating only there is no need for the jumper but it wont matter either way.

Edit: Grey to RH and white to W

If I disconnect (remove) my thermostat, will it keep the heaters from comming on?

Question by NEWTOME: If I disconnect (remove) my thermostat, will it keep the heaters from comming on?
I’ve got those electric baseboard heaters all around the basement but I also have a monitor, which I prefer to use. I don’t want to use the electric heaters, and there’s an outlet I need to use that’s on the same circuit. I thought I could disconnect the thermostat and that would disable them – would that work?

Answer by Tim B
Yes; there is no way for the connection to be made.

Which Thermostat do you Need – Line or Low Voltage Thermostat?

Which Thermostat do you Need – Line or Low Voltage Thermostat?

How do I know if my heater uses a line voltage thermostat or a low voltage thermostat? Is there a difference between the two? Which should I use for my home? With the dramatic drop in temperature this winter season, questions about thermostats are increasing. Before you turn your heating curiosity into a heating catastrophe, make sure you understand some basic facts about line voltage thermostats and low voltage thermostats.

What is a line voltage thermostat?

Directly responsible for operating your heater’s electricity, a line voltage thermostat works on baseboard heaters, electric wall heaters, and other similar devices. These high voltage thermostats – typically powered by 120 or 240 volt ACs – are of two types:

Two-wire (single-pole) and
Four-wire (double-pole),

Programable thermostat for electric baseboard heaters?

Question by NEWTOME: Programable thermostat for electric baseboard heaters?
Does anybody make one? The guy at my hardware store says nobody does. Any ideas?

Best answer:

Answer by rancidcrab
I believe there are. Just not with all the bells and whistles available in the market for low-voltage t-stats.

An associate of mine obtained one for a customer’s garage heater unit once.

First off, you need a LINE VOLTAGE thermostat.

I don’t have any catalogs at my disposal at the moment, but Johnstone Supply, Grainger, MSC, and host of other commercial suppliers would be where I would start.

Electric supply outfits like CED would be a good bet also.

If research efforts on your own fail, any electrician or HVAC contractor should have access to sources that sell line voltage thermostats.

Will natural gas be emitted from a gas wall heater if the thermostat is on but the pilot light is off?

Question by Lisa Simon: Will natural gas be emitted from a gas wall heater if the thermostat is on but the pilot light is off?
I may have left the thermostat on but the pilot light off on my sister’s gas wall heater. Will this emit natural gas or since the pilot light is off will the flow of natural gas be blocked?
It’s a gas wall heater, not a water heater.

So, Chris, what you’re saying is that if the pilot light is not lit, even if the thermostat wants to turn on the heat, the gas will not flow because the pilot light is not lit? Therefore, the house is safe?

Best answer:

Answer by Chris
It is blocked, there is a thermocouple that measures the pilot temperature, if it is not hot the gas will not turn on.

HELP! I am installing three 4000 watt in-wall heaters and I would like to connect them to one thermostat?

Question by Mikey B: HELP! I am installing three 4000 watt in-wall heaters and I would like to connect them to one thermostat?
I am installing three 240 volt 4000 watt in-wall heaters for my basement. They all have built in thermostats but I would like to connect them all to one thermostat. I don’t know if this is possible because I know at 4000 watts each that is too much power to run to a single breaker so I was going to run them all seperately to a 20 amp breaker for each unit. But is there any way for me to do this and still connect them all to a single thermostat? if so now, or is there other options?

Best answer:

Answer by EagleWatcher
1) Run 3 circuits to a box and install three double pole contactors each with a 120 volt coil.
2) Run 3 20 amp circuits from panel to box.
3) Attach to the line side of three contactors.
4) Extend circuits from load side of each contactor to heaters.
5) Attach circuits to heaters by-passing thermostats.
6) Install a single pole thermostat next to contactor box.
7) Feed this device’s line side to nearest 120 voly power supply. Connect this devices load side to contactor coil.
9) Attach 3 circuits to 3 double pole 20 amp breakers in panel.

Q&A: help! installing three in-wall heaters 4000 watts each and would like to hook them to one thermostat?

Question by Mikey B: help! installing three in-wall heaters 4000 watts each and would like to hook them to one thermostat?
I am installing three new in-wall heaters which run 240 volts and 4000 watts each. They all have a built in thermostats but I would like to hook them all up to a single thermostat to control the temperature of the basement. I obviously cannot connect them all to one breaker because they are too powerful so I was going to run each of them seperately to the panel with a 20 amp breaker. Is there any way that I can connect them all to the same thermostat, and if so how is that run?

Best answer:

Answer by pipe strangler
Why not leave them run on their own stats and that way once the area is warmed up enough it may only need one heater to keep it warm or they will each come on as needed if one area is a bit colder. Otherwise the only way of doing it would mean modifying each heater to bypass the built in stat and control them via a contactor and stat and run them all together off a 50 amp breaker or 3 contactors and a stat with 3 x20 amp breakers, quite a lot more expense.

How to wire thermostat for electric baseboard?

Question by Mike D: How to wire thermostat for electric baseboard?
I have a 240 volt electric baseboard heater and trying to update my thermostat. Old thermostat has two wires, new thermostat has four wires, two of which are labeled load and other two labeled line. Could you explain how I wire the new one? What is difference between line and load? Thanks.
Tstat wires are labeled L1, L2, T1, T2….Which is line and which is load? I lost the directions that came with it. Thanks

Best answer:

Answer by GG
You need to determine if the baseboard heater is controlled by line voltage (220V) or if there is a transformer stepping the voltage down.

If you determine this then you will know how to wire the stat. Most thermostats do not switch the line voltage (too dangerous).

I have a electric baseboard heater and the thermostat is missing on the wall. the wires are there.?

Question by jim l: I have a electric baseboard heater and the thermostat is missing on the wall. the wires are there.?
So will any thermostat work in its place?What wires go where or will the directions tell me?Thank you for your help.

Best answer:

Answer by Michael S
Electric base board heaters use a thermostat specifically made for them. They are usually 240vt and the stat acts like a switch with that much voltage going to them. You can buy them at electrical supply houses not hardware stores. First you have to determine what type you will need. Read the following:

Thermostats

You can install a thermostat in each heater or install a wall-mounted thermostat to control heat in the entire room. Installing a thermostat for each heater is more efficient, since it allows you to turn on only the heaters in the room that you need, rather than having all the heaters turn on together, as they would if connected to a wall-mounted thermostat.

There are two types of thermostats:

Single-pole thermostat: A single-pole thermostat controls temperature by opening one leg of the 240 volt line that feeds the heater. This means that even if the temperature dial is turned all the way down, voltage is still going into the heater through one line. This may pose a hazard to anyone who might perform electrical work on the heater without realizing that the circuit was still on. Remember: A single-pole thermostat does not turn off all power to the heater, you’ll need to turn off the power at the circuit breaker before electrical repairs can be made safely.

Double-pole thermostat: A double-pole thermostat controls temperature by breaking (opening) both sides of the 240-volt feeder line when the dial is turned down. This acts as a safeguard for people performing electrical work on the heater. However, to be on the safe side, you should always turn off the power at the circuit breaker, not at the thermostat, before making any electrical repairs.

Since they are inherently safer, you should always use double-pole thermostats, if possible. Usually, you can tell the difference between a single pole and double-pole thermostat by looking at the dial. A double-pole normally has an “Off” position on the dial whereas a single-pole thermostat does not.

Don’t know if you have another thermostat in the house that maybe you could take with you to the store as an example. Hope this helps.

Q&A: Wiring two King Cadet wall heaters to one thermostat?

Question by bigslamkylo: Wiring two King Cadet wall heaters to one thermostat?
I know this can be done I’ve seen it in new homes, best answer goes to any good diagram or a very well written description.

Best answer:

Answer by Jim W
Yes it can be done if the heaters are of small enough wattage that the thermostat can handle the power. Also check the manufacturers website, there was a recall on some of those units a couple of years ago.
Add the total wattage of the heaters, use a wire large enough to handle that current plus 25%, use a thermostat larger than needed for the heaters. Wire the thermostat to the first heater and the second heater off of the first. The heaters are wired in parallel, the thermostat is wired in series with the heaters. This is not to state that it may or may not meet current code. If you are uncertain about how this is done, call a qualified professional electrician to do the work.

Programmable Thermostat With Electric Wall Heater – Constant Click On/Off Ideas?

Question by Niko’s Mama: Programmable Thermostat With Electric Wall Heater – Constant Click On/Off Ideas?
In order to save some money over the winter months I researched and found a nifty thermostat, just like those for gas heaters, for baseboards. Our home we bought last September has electric heating throughout and had baseboards in all rooms. We have replaced the large baesboards in the living/dining room with in wall heaters with blowers for better heat circulation.

The way these heaters work is by a switch on the unit its self to set the temperature and it kicks on and off as necessary. With the way our home was wired before, we still have both heaters going to the thermostat as well, so we could technically turn the heater its self to max, and let the thermostat control it.

With the new thermostat that I got that is programable, you can set up times and temeratures (obviously) which can help concerve energy. Problem is, the heaters are kicking on and off constantly to maintain temperature, rather than letting it drop say 3-5 degrees before heating again. When I lived in an apartment with these heaters (both new) they did not kick on and off constantly to maintain temperature.

What I am trying to determine is how can I keep the programable thermostat or one like it, but get the darn thing to stop kicking on and off constantly. Its not just the anoyance factor, but doesnt it take more energy to kick on and off and on and off, than to heat as necessary? I would assume we would still save money on our electric bill with the program feature (lower temp while at work and sleeping), but the fan kicking on and off is just irritating! My husband wants to get rid of it entirely but I love the program feature.

Best answer:

Answer by B-Notable
First things first. I know of no digital thermostat that would give you a 3-5 degree differential, they are generally set up to give you a very narrow control band to keep the room at a near constant temp, 1-2 deg. at most. Second, no it does not cost anymore to cycle the heat like that, electric heat is a resistive load and draws no more on start up. The fan will but on a wall heater the fan is so small that the inrush is negligible. Some digital stats allow you to set the cycle rate which will change the off and on cycle times, you would have to read the manual for your particular stat. I know that the Honeywell digital series of line voltage heating thermostats has this feature. Hope this helps.
