I’ve got a new ct100 plus that I installed back in October, running @RBoy 's enhanced thermostat DH version v04.00.00 . It’s been working great, up until A/C season started. There’s nothing wrong with it responding to commands, but it seems that the temperature reading does not necessarily reflect when the room is cooling down, causing the A/C to keep running for extended periods of time.
Tonight, we came home around 7:15, the house was 77F, and the thermostat gets set to 76F on returning. WIthin the first ~10 minutes, the thermostat is reading 76.5F. Two hours later, the A/C is still running, and the living room (next room from the thermostat) is down to 74F, the master bedroom is down to 72.5F, and the thermostat is still reading 76.5F.
So I know the air is cooling around the house, well past the cool setpoint, but it’s like the thermostat doesn’t want to get the drift and recognize that fact.
Any ideas? (also, it is powered by C wire)
