Compressor/Auxiliary Interlock (Comp/aux)
This parameter sets the sequence of operation of the
heat pump compressor and auxiliary heat. The choices
are off and on.
•
Interlock Off (in heating mode only)
If the heat pump is not able to satisfy the heating
setpoint, the auxiliary heat is energized at the
same time as the heat pump stage. This typically
applies when the air handler heat pump coil is
installed before the auxiliary heat (all electric
systems).
•
Interlock On (in heating mode only)
If the heat pump is not able to satisfy the heating
setpoint, the auxiliary heat is energized and the
heat pump is shut off. This typically applies when
the air handler heat pump coil is installed after the
auxiliary heat. There is a 2-minute delay to restart
the heat pump after the auxiliary heat is shut
down.
