Re: Honeywell Programmable Eletronic Thermostat model...

There are so many products, we cannot help without the model no. Try typing 'Honeywell programmable electronic thermostat' into google and searching for an image of your thermostat, then get the model no. Then you might be able to get some help.

How do I get my honeywell system up and going?

for now, put switches on thermostat to hear and press the up arrow button to the desired temp. All your programed temps will take more explaining and it would be best you secure a owners instruction book from home depot. oif anything, buy thr same thermostat and either keep it or return it . I'd keep it regardless, read the pmphlet,program you heat and a/c before returning for refund. Don't destroy packaging and give them back everything. You will also need two AAbatteries. Good luck.

Honeywell rth230b won't shut off heat

Sounds like a relay sticking. Possibly in the thermostat or possibly the furnace relay at the furnace. The next time it happens, unplug the thermostat from the wall. If the furnace still runs then it's the furnace relay.

Hope that helps...
