Heat Pumps and Electric Heating - programable thermostat help

In my new apartment I have three baseboard electric heaters. Atleast that is what I think they are called. I know little to nothing about these things.

I called the Honeywell customer support line asking what programmable thermostat I could buy. They asked me about my old thermostat. I read of the old thermostat to them that it is a Honeywell model #T498B.

They then said they would need information about the baseboard electric heater so that they could recommend a programmable thermostat. I told them I didn't have that information, so I asked if I wanted a regular thermostat, what should I get. I figured that if they atleast told me a regular thermostat, that I could surely find it's programmable version. They recommended the CT62A.

I found the installation instructions at http://customer.honeywell.com/Techlit/pdf/69-0000s/69-0829.pdf . However, I can't find anywhere to buy this thing.

I think the thermostats are connected to a 240 V line. I looked in the breaker box and there are two pairs of two 20 (i guess that is 120?) lines connected that are marked "Heating." I have three thermostats throughtout my whole apartment. So I guess two of the electric heaters must share a line. The wiring to the thermostat seems simple enough. It's two black wires connected to one side (i guess thats the two 120 lines) and two black wires connected together (shorting), connected to the other side.

Does anone know what programmable thermostat I could purchase? Or where I can get a CT62A? I'm also on a budget, so let me know if this is going to kill the bank.

What you have is a 240 volt, Line Voltage, thermostat.

I do not know of any progrmable line voltage stats.

You should be able to go to any big box store, or electrical supply house and get a non programable stat.

What is a Big Box store?

I found the old one I have. It is good up to 19 amps.
http://www.honeywell-thermostat.com/honeywell/t498-thermostat.htm

It asks If I want a 2 wire or 4 wire. Which do I have? I think I have 4 wire.

I also found this programmable one.
http://www.honeywell-thermostat.com/honeywell/TL8230A1003-thermostat.html
However it says 3600 Watts at 240 V. MY math tells me that goes up to 15A. Is that enough?

I also found another one that seems to go up to 18A.
http://www.honeywell-thermostat.com/honeywell/t4700-thermostat.htm

So I guess the question is, how many amps are going through my wires?

Big Box is places like Home Depot or Lowes.

I know we at Home Depot have the Honeywell Programable Line Voltage t-stat.

I don't recall off hand what it cost, but we have it.. (at last at my store we do) I can look tmrw and post back with more info if you want.

Okay thansk for the help. I found the non-programmable one at home depot. But it is not in store.

Honeywell
CT62B Electric Heat Thermsotat
Model CT62B1015
Catalog/ Internet Only


However, I didn't see anything programmable. I even looked at other brands.

In any case, I would still like to know how many amps my electric heater draws. I guess the only way to know is to turn it on with the new thermostat and hope the thermostat doesnt get fried?

I think this is my best bet, if I ever figure out whether my electric heater draws less than 15A. Too bad it isn't available at home depot or lowes.

LUX makes a programmable line voltage stat model
BBLEV1-005 it is 120.240 single pole only.

Just using google or any other good serach engine yields resutls.
If you want 7-day programmable, this place has the TL8230A
http://www.air-n-water.com/product/TL8230A1003.html $69.95 There are others, but this is the only store that I found that has any customer reviews.

Thanks for the info.

I am worried that if I order from an online retailer, then I won't be able to return it if it does not work out.

I think it might be best if I buy the non programmable version (Ct62b), which is $13 from homedepot.com and see if it does not get fried. But it is out of stock at homedepot.com. Too bad I can't find any big box companies that have it at the store. :/

sddiy,

I forgot to look today on the t-stat, where are you out of? (your home depot city/state) I'll look in the system and see if Home Depot near you has it or not.

The nearest home depot to me is in Yonkers, NY. There is also one is Nanuet or Nyack New York. Please check for the non-programmable (CT62B) one and the programmable one (LineVoltPRo 8000). Thanks for the help.


more precisely,

601 Sprain Road, Yonkers, NY 10710

2024 Palisades Center Drive, West Nyack, NY 10994

I will look, and post back tmrw!

Ok, I looked you have this t-stat in all 3 stores you mention about. I wil post a picture when I get home for lunch.

It's a Honeywel 5-2 Electric baseboard t-stat. model #RLV430A

SKU# 268-221
$52.00

Thanks! I'll pick one up during lunch.

Although, it doesn't look to promissing since it is only rated for 3500 Watts (http://www.honeywellcentral.com/product/0-85267-26454-9.html). While my old one was rated for 4560. But it could work, so I'll try it out.

What is home depot's return policy on these things?

Can be returned with your recept in 90days if it don't work out for you.


Before this came out, I had something close to this but not programable and it worked for us in our apt before we brought a home, and it worked well. It even cut our power bill down cuz it has a better temp control.. The old standard t-stat had large temp swing (large as 5 degree) it was hot or cold.. With the new t-stat, temp stayed on the money of set point.

Thanks for all your help. This did the trick! Everything seems to be working perfectly. It's a wonderfull thermostat.

I got two minor issues still,

1) First time I turned on the thermostat it smelled like burnt. I guess I need to clean the heaters somehow? Never done something like that before.

2)I slept at my new place for the first time last night, and I was frozen.

I had it programmed for 62 degrees when I was asleep and 70F before I woke up. The thermostat said it was 70F when I read it in the morning, but I was pretty damn cold. At my office it is about 70F and I feel comfortable if not hot.

But maybe it is just me because in my old apartment it was incredibly hot and I couldn't control the temperature. So I got used to sleeping in tropical conditions. I'll raise it up to 68F while I sleep and 75F when I wake up tomorow morning.

If you got a smell, the baseboard heater may need cleaning.. On the ends there should be a screw or something to pop the front plate off.. otherwise, take a vaccume and suck from the bottom and I take those office max can of air and blow down from top to remove any dust build up.


Damn, that's hot for me! lol I run ours at 60 at night/away, and 68 when I am home... Just slowly work your way down over time, and you will get used to 68

Hey,

Just wanted to stop in and check with you to see how things are working out for you.

I have electric baseboard heaters controlled by a manual thermostat. While trying to find a programmable thermostat for electric baseboard heaters, I stumbled across this posting.

I bought the Honeywell 5+2 Day programmable thermostat Model RLV430A. When I tried to install it I am encountering a problem. The manual thermostat fixture has 4 wires running into the thermostat [2 black and 2 red] while the RLV430A has just 2 black wires. The manual has instructions for a 4 wired system, however I cannot understand how to connect the 2 black wires of the thermostat to the 4 wires in the fixture.

The manual for the thermostat is here:

http://www.homedepot.ca/wcsstore/HomeDepotCanada/images/catalog/b7867367-6c05-4c82-a97c-648044b91564.pdf

I would appreciate any help you can provide on this matter. FYI, I am in Seattle, WA. Thanks in advance.

This how you can do it.

Wire 1 coming from the breaker (I am guessing that wire has red/black?)

Tie the black and black together.

Take the red to t-stat's wire, and take other t-stat wire and tie that to the other wire's red. (t-stat between the red wires.)

That Worked! Thanks Jay11J!

Glad to hear that it's working for ya! Now watch your electric bill go down, and increese in comfort.. I know ours did when we used to rent an apt. with electric heat.

I have to replace 2 thermostats on my electric radiant ceiling heat. i have looked at various web pages and emailed honeywell direct. The old t-stat lists 18amp 277vac and 22amp 12/240vac. I would like to get a 'good' t-stat for the main living area as right now the heat is hot or cool... Any idea I have 3 numbers that honeywell suggested ct410a/b ct60b, ct62a/b How am I going to know if i have 2 or 4 wire? Also does Home Depot or Lowes carry such and animal that I can easily go and get. thanks

Home Depot has a programable line voltage t-stat in stock... That is what this thread starter brought for his place.

Model is RVL430, It's about $54.

I have electric baseboard heaters, and want to replace an existing programmable line volt thermostat ( Honeywell model CT1950 ) with a non-programmable line volt thermostat ( Honeywell model CT62B ). It should be simple, I think, but the new thermostat has 4 wires, 2 red and 2 black, and the old thermostat has only 2 black. Do I just connect the two black wires to each other, and does it matter which black wires connect to each other, and put a cap on the two red; would I cap these individually or to each other? The packaging for the new thermostat says that it is compatible with a 2-wire line volt electric heat.

Why are you taking out a programble t-stat to a manual?

You can save money with programble one.

You need to use all 4 wires.. Tie the red wire to the other two sets of wire that was capped together.

There are two red wires. Are you saying to cap black-to-black and tie a red wire to each of the two sets of capped black wires?
Thanks for the help.

Hope this helps.

I bought this 4 wire t-stat
2 power, 2 line
replacing manual ancient 2 wire one
from wall 2 black was contect to red / black
from wall 2 white tied together
I tried different ways to do it but couldnt figure it out just the power one (red/black) from t-stat connect to both black I get power, only when white are connected from wall are connected.
then there the line wires (red/black) from t-stat
I got to be wiring it wrong

Black power to t-stat black.

T-stat's black to black line to heater..

White power to T-stat red.

T-stat's red to white line to heater.


Should work.
