Honeywell rlv430 is wired in correctly, yet one baseboard heater is always on, regardless of the temp Its set at

Need to start with comparing the temp in the room to the temp the heater is set to. A t-stat will read +/- the actual temp. If their not even close, then the heater will run trying to reach the temp the t-stat is set to.

There is power coming in the Honeywell thermostat RLV430 however the display pad is always blank. Sometimes it goes on and keep flashing on and off and then goes blank again. I changed the thermostat...

Richard, when you say base board, do you mean the subbase where the control wires connect? I am thinking you just changed out the front part which is the stat, leaving the old subbase on? If this is the case, make sure you have 24 volts at the R and one of the other terminals, but change out the subbase as this is where your problem would be, all of the displays circuitry is in that section of the thermostat. This will solve your problem. I take it this stat has no batteries for the display? If it does, change them out with good new ones. Please contact me if you need more help. Use the comment box, so I can check it when I can.

I just installed an rlv430 and it works fine, but the backscreen light does not come on. The manual says that it should turn on for 12 seconds when any button is depressed. What could be the problem???....

Hi, the only problem that it could be if the display and system is working good, is a faulty back light from the factory. All you can do is take your receipt and the stat back, and exchange it. It has nothing to do with the way it was wired, its just one of those things that happen from time to time. Even though its new doesn't mean it will work right. I know its a pain, but that is the problem as you have 24 volts there or the unit wouldn't run, and that voltage lights the back light, so its not right.

I am installing a new thermostat for my baseboard electric heat. The electric box has 2 wires comming into it. So I have 2 black, 2 white and 2 ground. The old thermostat had a place for all 4 wires (one...

One wire is "IN" the other is "OUT" A Thermostat works by "Breaking" the "Phase" line. It is just that simple. You usually have a pair of wires that connects, on the "Hot" side, to the always power ON line, & neutral. The Circuit, or Load, on the "Cold" side, has a a pair of contacts that open & close depending on Thermostat, in series with that conductor. Hot Contacts Cold P In-------------------><-----------------P Out

Thermostat burning walls

your thermostat may not be made for electric heat, if not then your wiring is overloading the thermostat causing the wires to heat up.

Thermostat installation

On paul 306, I don't have any info on you're system, but the old thermostat that has the smaller wires with the colors you described is a low voltage (24volt) controls. The new one you purchased sounds like it is for a system that is made for line voltage (120 volts or more) connecting this to the unit may have bad results. This also may apply to GUEST.
COACOOCHEE, the white and black coming into the box is the line, even though white should not be used for line, the connections for the other side of the thermostat is the load. The new thermostat you have be a single pole break as opposed to the old one may be a double pole. You should have a meter to check the voltage coming into the box, it may be 120 or 220 depending on what you have. Without any more info I cant be sure, but you may be able to connect the black wires to the switch and the white together. But it would be wise to test with a meter to be sure before doing this.

get in front of one of the thermostats and call Honeywell at 800-341-0110. If you are prompted, tell them you are an installer and seting up the thermostat for the homeowner.


Good Luck.
