Ok, so I recently purchased a CT101 thermostat. I followed the directions and labeled all of the existing wires. I also took a picture of the old thermostats wiring. That said, I cannot get my system to blow cool air.
When I set it to Cool I get warm air and the house temp increases
When I set it to Heat I get warm air and the house temp increases
I swapped the W (orange) and W2 (white) wires. On Heat it produces warmer air
I moved the R wire from RH to RC (there is a jumper so it really shouldn’t matter) and I still got warm air on the Cool setting.
I remove all wires except Y and R and set it to cool and I got warm air
I hooked the old thermostat back up (was getting too hot in here) and it worked as expected, it quickly took me from 80 back down to 75.
I then wired the CT101 back up directly to the unit (I used the wall plate previously) and same behavior.
I am using only the manual heat and cool modes at this point (not auto). I have paired with ST to see if that works and no issues there (same behavior hvac wise).
Does anyone have any ideas? I did send an email to Radio Thermostat support this morning, but I"m not sure what I can reasonably expect there.
