Question about Honeywell Programmable Thermostat Heater

2 Answers

I have a Honeywell programmable thermostat that I've had for many years. Recently the batteries went dead. We replaced them, reprogrammed it and started the furnace up. When we came home after and hour or so, the house was hot and the thermostat temp showed 50 degrees when it was actually 74. The furnace kept running because it read 50 (I believe). We shut it down to stop the furnace.

Reset after power outage


Most programmable thermostats have batteries to keep the program from being lost in a power outage. If you thermostat has dead batteries or no batteries a power outage will cause the thermostat to revert to a default setting and it will have to be reprogrammed. Hope this helps.

Per manual do this: System set to Off Remove batterie Replace IN REVERSE POLARITY POSITION or 5-10 seconds Put back in with CORRECT POLARITY Reprogram per sticker on back of thermostat. Done. Just did this myself and it's simple and effective! PaulHaven

I replaced the batteries after seeing a display of "EEE" and since then I get no display whatsoever. Honeywell/36


The internal sensor could be bad, try replacing the batteries again, be certain the polarity is correct, the sensor is inherent to the stat and the stat must be replaced.

Honeywell Chronotherm IV Plus requires frequent resetting.


Check to see if you have wires going to a C/C1 terminal. The older chronotherms used a transformer to supply 24 volts to power the clock. If in fact you do have these terminals, then I would suggest checking the output voltage on the transformer, (secondary (24v)side) to ensure it isn't close to dead. Hope this helps
