Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater

1 Answer

Cannot get thermostat to work with previous owners programming.

Just moved into an older home with a Honeywell thermostat. Previous owner set programs, now we cannot cancel the old programs. How do you cancel the old programs set for multiple times a day and just use the manual setting. Sorry cannot tell what model it is. Thank you!

I receieved a SYLVANIA 6432GG TV with a remote. The remote control doesn't work. The previous owner had programmed a Comcast remote control to use on the TV. I don't know how to reprogram t


GOOGLE THE MODEL NUMBER OF THE SET (IF ORIGINAL REMOTE) WITH "manual" which would get the owner manual to do this.

Each set is different in this process.

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.
