Help needed - Thermostat
I my dealer asked me to use an HVAC technician to install the Control4 Thermostat. I have a carrier unit and the current thermostat is Honeywell Focus Pro 6000. When the technician came today and tried to install the Control4 unit something did not work right: the HVAC will start working and suddenly stop for no reason (did not reach the required temperature); after setting the temperature to 74 it suddenly jumped to 85 and etc. Did anyone encounter this kind of problem in the past? can it be a problem with the Control4 unit? maybe something was not right with the installation? I am not an expert but it seems that he connected the wires correctly and kept the set up on Power Stealing and the remaining default setting which match my HVAC unit (i.e., Conventional and etc). Power stealing causes funky issues with some modern HVAC systems. The "stealing" causes the relays on the system to have issues which is probably the exact problem you are experiencing. I have a new high efficiency system on one floor that was very flaky when set to power stealing. Once I ran a common wire, it works without any problems.
