Replaced Thermostat and A/C will not kick on
I am attempting to replace a Totaline thermostat with a Honeywell RTH6300B programmable thermostat.
I have both Carrier A/C and gas furnaces for both zones (2).
The units are all 3 years old.
After replacing the thermostat on the first zone, I can only get the heat to kick on and it works fine. I try to test the A/C and the fan and cannot get either to kick on. I have made sure the circuit breakers are all on and the thermostat is set to cool with the temperature set below the current temperature and waited several minutes. I have read there is a 5 minute cool down on some systems.
I seriously doubt I have mis-wired the 5 wire system and have removed the jumper per Honeywell instructions.
Any ideas?
