Well into a remodel of a 1997 built home. Air Handler/Compressor A/C unit replaced with a Rheem system in Oct 2009. Previous owner kept the Carrier Comfort Zone Controller. House divided into 3-Zones. Valves are accessible in attic space. What are my options for replacement of control system?
The system control was operational until I failed to turn off the Ckt Breaker that powered the 24vac transformer feeding the Zone Interface Control Board. I blew the output transister Q1 on the board when I remeoved the Zone Thermostat. Any option for getting the board repaired? Is there a Circuit Diagram available?
But the long term solution is a new control system, so looking for some professional advice before I call the local HVAC Contractor.
