Is this a new installation? If so the elements may be pulling more load than the circuit can handle. That or you have a weak breaker. See what size the breaker is I.E. 20, 30, whatever, and see how may watts the heater is making. Divide that into volts (ohms law) and that should give you the amp draw. If its higher than the number on the breaker, then its overloading. If its lower but the breaker still trips, then change it.

How do I wire a Honeywell thermostat

Can I start by saying I am not in anyway saying to do this alone it is dangerous but if u must follow each step start by being safe shut off the breakers good luck here to help
Step 1
Turn the air conditioning and heating unit off by flipping the appropriate circuit breaker. Test the unit to make sure it's off by turning your existing thermostat to the "On" position and seeing if it turns on. Wiring a Honeywell thermostat when the circuit breaker is on could cause you to blow the transformer that powers the HVAC unit Step 2

Connect the red wires to the thermostat RH, thermostat RC or thermostat R terminal. The thermostat RC terminal has a jumper wire between thermostat RH and thermostat RC. The thermostat R terminal operates both the heating and cooling units, and contains an internal jumper wire. Basically, your red wire on a Honeywell thermostat is the hot wire that run. Step 3

Run the green wire to the thermostat G terminal. The green wire controls the relay that operates the blower, and it controls the fan. Step 4

Control your air conditioning when you connect the yellow wire. It connects to the thermostat Y terminal Step 5

Hook the white wire to the thermostat W terminal to control the heating unit

Honeywell Chronotherm iv Plus power cuts on and off

There's a trouble shooting guide here, you need to check for the presence of 24V when it goes blank, and trace back to where it's disappearing (I assume it is losing the 24v, if not you'll need to go through the installer setup or read on...
My first thought would be to check the wiring which has been touched last if it started doing that after you had coil replaced.
As an aside I'm not sure which model you have but if it has batteries you should replace them (I don't think it does have batteries but not seen a model iv so I'm unsure)

Can't set temperature

first go turn breakers off at indoor unit or if gas turn switch or unplug for thirty seconds.should be a hold button on thermostat , set desired temperature and press hold allow five minutes to go by.listen doen anything at all happen at unit.
if nothing happens after five minutes remove sub-base from wall and at the thermostat jump with a wire the r terminal and the white terminal see if it comes on if so you got a bad thermostat most likely.

I cannot get my heater to shut off when it get to hot in the house , i have it on 60 and auto and still running. I have to turn it off.

sounds like maybe you have a wire touching somewhere in the thermostat or the thermostat itself is failing, are you turning the power off to unit or turning the thermostat to off .... if you are turning power off then try this frirst turn you thermostat down as low as it will go a wait 1 minute 30seconds to see if it goes off if not then (at thermostat) remove the wire hooked to "w" terminal which if done correctly should be a white wire ... wait a few minutes and see if the unit shuts down ..if it does not see if you are still blowing hot air as the fan may just be running...if the heat portion stops ,but you still have fan then remove the "g" wire also and wait about 90-120 seconds and see if the fan goes off... if all goes off then either you thermost is still calling heat for some reason or you have one of those wires touching the "r' wire somewhere making the call for heat....
***** if you are turning the thermostat to off and the unit is going off then you most likely just have a bad thermostat and for some reason one of the relays are stuck on thermostat

My honeywell RTH230B won't do anything. I put fresh batteries in it, tried everything and nothing happens. What is the probelem and what can I do?

If this is a typical air handler unit then turn the fan switch to on, if the fan does not come on then you have a control problem or no power to unit. Check fuses/Breaker.

If fuses and breaker are ok then try this. Turn the power off to unit, try and locate control board usually
located in the lower panel where the blower might be.

Disconnect thermostat wires that go to probably
r/w/g/y/c and remember what color goes to where.
If you can make a jumper wire or you have aligator
clips, jumper r and w. Put door back on, turn power on and heat should start up.

You can also put a jumper between r ang g terminals
instead and the fan should come on.

If either of the two cases happen, then you need another thermostat or check wiring to thermostat.
Another possibility is that there could be a car fuse
located in the control board that is blown

Good Luck

AC wont kick on....

The first thing to check is your breaker box. There should be one double breaker for the air handler unit, that's the inside unit, and one double breaker for the compressor, that's the outside unit. Check both breakers. If you're not sure if they've be thrown, click them toward the outside of the breaker box (off position) and then click them toward the inside of the breaker box (on position). If the breakers are on and you still are not getting any A/C take a look at your compressor, (outside unit). If the fan is running at least you're getting power. However, your compressor down inside the unit may not be getting power or it may need to be replaced. The compressor has a start-up cap. If this cap goes bad or the wires from this cap fry or corrode away, this will also keep the compressor from starting but the fan will still run. If the fan is not running it could be caused by a faulty relay inside the compressor cabinet. This relay is supposed to open and close based on a low voltage signal from the thermostat. I believe it's roughly 24 volts. This relay switches on and off the 240 volts for the compressor and the compressor fan. Often this relay goes bad or the wires leading up to it fry. If you?re going to work on the unit yourself make sure all power is shut off. There should be a shutoff switch on the outside wall near the compressor. I?d also shut the breakers off.

Readings disappear on thermostat for awhile then come back

Hi Linda,

There are a few things that cause this:

  1. When the heat is starting, it will sometimes go blank for a few minutes and then resume.
  2. Most have batteries, replace them with fresh new ones, if the electricity goes out while you are away, the batteries will keep the settings.
  3. Have someone check the house when it is extremely cold or hire a service to monitor. Your alarm company can usually add temperature sensors to your home, it will add a little safety net for you.
Hope this was helpful, please rate my answer.
