LOCKOUT
Auxiliary heat will come "on" whenever thermostat calls for heating and outdoor air temperature is below the value set for aux_heat_temperature_lockout. It remains "on" until the thermostat is satisfied.
DEADBAND
(default) Auxiliary heat will come "on" when indoor air temperature drops by more than the value set for aux_heat_deadband below the heating_setpoint. It remains "on" until the thermostat is satisfied.
TIMER
Auxiliary heat will come "on" when heating_system_type has been "on" for longer than the value specified for aux_heat_time_delay. It remains "on" until the thermostat is satisfied.
Default
When auxiliary_system_type is set to ELECTRIC, the default setting for auxiliary_strategy is DEADBAND (with 2 degF).
