Supplemental heat, provided by electric heating elements may be necessary in some areas
when heating requirements for indoor comfort exceed the capacity of the heat pump system.
When supplemental heat is required, units with the Watt Restrictor will restrict the amount of
supplemental electric heat that can be energized dependent on the heat output of the heat
pump (temperature of the air leaving the indoor heat pump coil).
The Watt-restrictor utilizes sensing devices in the unit to sense the air temperature leaving
the indoor coil and disengage unnecessary heating elements when that temperature is at
least 85°F [29°C]. (In this mode your system is controlled by the first stage of the wall thermostat.) This occurs only when the second stage of the wall thermostat calls for heat.
Since the heat output of the heat pump is dependent upon the outdoor air temperature, this
control performs the same function as a field installed outdoor thermostat.
An additional benefit of the Watt Restrictor is that it can sense a degradation in heat pump
performance due to causes other than outdoor temperature and react accordingly to bring
on more supplemental electric heat.
