    Thanks for the tip. It happened when it was in heat mode. I actually turned it to fan mode for awhile and then back to auto mode and the fan turned off. It was very warm here today so did not need AC or heat. I do not know what tstat to man means....sorry.

I installed a new thermostat on my hvac system and the heat is not working anymore.


On that thermostat there is an R and an RC wire connection, the R is the power wire for heat and RC is the power wire for cooling. If you connected the power wire (normally red in color) to the RC only the fan control and AC control will work, there has to be a jumper wire between the R and RC terminals (assuming there is only one control transformer) for both the heat and cool functions to work.

Compressor relay switch


What temperature is this heat pump being run at? If it is low ambient temp outside this may be running in what is called defrost mode to where the compressor will run without a call for heat. This seems normal to me as long as the setpoint temperature is being reached.

Honeywell Chronotherm iv fan keeps running even when heat and cool turned off. How do I turn it off?


Assuming you have the fan switch of your thermostat in AUTO, it sounds like a stuck Fan Relay. If the fan relay is stuck, your fan will continue to run as long as there is line voltage being fed to your unit. This relay could be an independent component or it could be an integral part of your control board. Have an experienced, qualified service technician check it out.
