TB8220U Commercial Thermostat keeps running when temp is right

I have a heat pump that runs pretty much all the time even when the inside temp is were it should be. When i check the temp of the air coming out its about the same as the inside temp. Shouldn't the entire thing shut off if its set to 66 and its 66 on the screen. The temp does not raise above what its set to but does not shut off very often when the temp is the same.

The temp coming out of the vent should be 20 to 25 deg more then room temp and if AUX heat kicks in the temp should be even more.

Heat pump runs on electric when outside temperature is higher than cutin


Check your thermostat and heat pump owner's manuals. Thermostat may be programmed to require electric heat at higher temps. Also could be bad outdoor temperature sensor tied to
Heat pump system controls (I had that problem) When was it installed? Warranty thermostat and or Heat pump? Call installer
Thermostat programming is a headache. No help from installer? call customer service heat pump and thermostat. Some possibility of bad installer wiring. There is also a heat pump "defrost" cycle. Usually the Electric coil will turn on to compensate for the Defrost cycle which is just the standard air conditioning mode therefore moves heat from inside to the outside coil to melt the frost. This cycle may be occurring too often. I had that problem. Fixed under warrantee.
Heat pumps are complex machines. The controls even more.
You need a tech, hopfully you are still under warranty.
Hope this helps.

What does it mean when the aux is flashing on my thermostat?


I assume that you have a heat pump system. If this is the case, the outside temperature is probably lower than the heat pump is sized for and it is using the auxiliary heating system to keep up. The auxiliary heating system usually is an electric coil in the heat pump unit which supplements the heat being produced by the heat pump. This is normal operations and does not indicate a problem with the heat pump, it is just really cold outside. If it is not colder than usual outside, there may be a problem with the heat pump and you should call a heating contractor to check it out.

My honeywell Thermostat reaches the heating temp. but the fan will not stop running.And yes the fan is set to auto.It just keeps running and running and running.It stays the same temp but will not shut off...


I want to give a simple explanation before I go any further. On the heating side of a unit even though tthe temp has satisfied the thermostat, the fan will run until it cools down the plenum where the air flows from the air handler. There is a bimetal switch called a fan limit that operates the blower when the plenum reaches the temp set on the fan limit switch. Now if your fan keeps running even after the plenum chamber has cooled down, then you could have a fan limit switch that is stuck in the run position and must be replaced in order to correct the problem.

On the old thermostat how many and what terminals did you have?
Usually
R = Red One Side of 24 volt Transformer
RH = Usually jumpered to R or RC
C = Common the other side of the 24 volt transformer opposite the R
G = Green Blower
Y = Yellow Cool
W = White Heat

Did you keep notes or remember all the stat wires and terminals? 20kw should heat your home very well. Has the unit heated the house good after you changed the thermostat?

Temp set at 68 degrees but goes to 66 and the heat pump never shuts down has an electric aux


Depending on the outside temp. your heat pump might not keep up with the demand. It is not economical to run your heat pump in temperatures at or below freezing. Doing so could cause compressor failure and these are not cheap to replace. I would be running the aux. electric in low temps.

How do you get the pump to circulate less. It seems like its running all the time to keep the temp up? I have a ozone system also could that be affecting it?


Your pump should be two speed if it is wired right there will be an overide in the way of a timer switch and or a therapy button ether one of these will keep the pump running at full speed the low speed should only run off the thermostat otherwise the water runs to fast to be heated properly. And no your ozone should have no effect on this. So check your timer and your therapy spa side.

Heater running continuously


Sounds like you have a problem with your heat pump. Your aux heat is a electric coil. how old is the unit when was the last time it was serviced? How cold is it out side?

Continues to run


yes I would switch it over due to the fact that the balance point reached. Since I'm not there to look at the system monitor the actual temperature inside and if you cannot maintain the setpoint on the thermostat you may have to bring it back on. I've seen recently that there was not enough backup heat to keep the house warm enough during cold spells. Stay warm.
