Gas Furnace turns off (Thermostat satisfied)
69
Heat Pump turns on
65
Gas Furnace turns on, Heat Pump turns off (Heat Pump is again unable
to satisfy Thermostat), (Backup heat counter reaches 3
rd
strike and Heat
Pump is locked out for 2 hours), backup heat counter is reset if Heat
Pump is running for more than 20 minutes and does not call for backup
heat
71
Gas Furnace turns off (Thermostat satisfied)
69
Gas Furnace turns on (Becomes Primary heat source)
71
Gas Furnace turns off (Thermostat satisfied)
After 2 hour lockout
69
Heat Pump turns on (Resumes as Primary heat source)
65
Gas Furnace turns on, Heat Pump turns off (Becomes primary heat
source) (Heat Pump is locked out for another 2 hours)
71
Gas Furnace turns off (Thermostat satisfied)
After 2 hour lockout
69
Heat Pump turns on (Resumes as primary heat source)
71
Heat Pump turns off (Thermostat satisfied)
(Backup heat counter is reset any time Heat Pump satisfies thermostat
setpoint and does not need Gas Furnace)
