Problem:Heating coils staying on at the cool down cycle.
Replaced bad hunter t-stat(batteries not making good contact) with Honeywell-rth-111 series t-stat.
When t-stat set temp is reached t-stat turns heat coils off, but they are really still on. Once a little time passes fan and heat elements turn off.
Will this hurt something? To me it seems to keep the double wide warmer. Over shoots temp by 2 degs, not too bad.
Put the hunter t-stat back on and same thing. Worked before t-stat change out. I now have the Honeywell hooked up.
T-stat wired as follows-B-O-G-Y-W-R-RC
B and O are not hooked up.No heat pump
G to G on furnace
Y to Y " "
W to W " "
R to R " "
RC has blue wire which is tied to red wire from outside air compressor(Jumper removed)
Now for outside compressor wiring.
3 wires coming in. red,white,green
red to blue wire to t-stat
white to y terminal on furnace
green to C terminal on furnace.
Heat works fine except coils not shutting down for cool down. When fan shuts down heat coils shut down.
Not sure if air cond works too cold to try, but did work just before cold weather.
If this is not a big problem I can live with it.
Hope this is enough info.
Thanks
Bob
