Installed the Alarm.com Intelligent Thermostat (ADC T-3000) on Wednesday evening. Immediately noticed the ambient temp was reading four degrees higher (74) than my previous thermostat(70). I just adjusted the set point up a few degrees and didn’t think much of it. Over the next 24 hours the thermostat cycled my heat pump over and over attempting to cook the house. It would run for maybe five minutes and then cut off, wait maybe five minutes, then restart. The ambient temperature kept climbing and the unit kept this on and off routine without ever getting close to the set point temperature. Each time the thermostat would go to orange display with “Protect 5 Min” on it. After attempting to correct in settings last night, I switched the thermostat back to my original to avoid damaging the compressor from so much cycling. It then ran for over an hour to cool the house from the 79 degrees it had reached to the 70 degree set point.
Everything was wired exactly like it was on the old thermostat. Blue to C, Orange to O, White to W, Yellow to Y, Red to RH (selected RH only on menu to create digital jumper to RC), and Green to G. Any way this could be a faulty unit out out of the box? With the ambient temperature off significantly and the cycling, it makes me think that unless there’s some advance setting I’m not aware of.
