Upon my arrival I replaced the comfort control system. Went through the manual and set it up properly. Tested the system and it would not come on. During the set up i mistakenly hooked the new comfort control to the wrong unit. I found this out while on the phone with tech support. While on the phone with tech support we found that the systems dip switches were set up to be a cool only system. Corrected the switches and the comfort control and everything is operating properly. I then had to reconnect the comfort control for the office and was having issues with the reconnect. Got it reconnected and tested the system and everything came back on and was operating properly.
