How to Set-up Lockout Temperature for Heat Pump

Heat pump settings allow for adjustment of compressor lockout
temperature and auxiliary (secondary) lockout temperature
ELECTRIC BACKUP HEAT
Auxiliary heat lockout temperature:
»
– Auxiliary electric strip heat won't run
above this outdoor temperature.
– Must be at least 10°F greater than heat
pump lockout temperature.
Installer Wizard > equipment setup >
heat pump > heat pump settings > aux
heat lockout temp
Heat pump lockout temperature:
»
– The heat pump compressor won't run
below this outdoor temperature.
– Must be at least 10°F less than aux heat
lockout temperature.
Installer Wizard > equipment setup >
heat pump > heat pump settings > heat
pump lockout temp
When the outdoor temp is between the heat
pump lockout and aux lockout temperatures
– Backup heat is requested immediately if
the difference between the heat set-point
and indoor temperature is greater than 4°F
– Depending on load conditions and system performance, the thermostat
will wait to request backup heat. Backup heat will only be requested
when the temperature is not rising to meet the heat set-point in a
reasonable amount of time.
DUAL-FUEL BALANCE POINT:
Balance point lockout temperature:
»
– The heat pump will turn on above this temperature, and with v2.7 and
higher software the gas furnace will turn on if the heat pump cannot
maintain the heat setpoint.
– Only the gas furnace will turn on below this lockout temperature.
