Zone 1 Weight % Zone 1 relative weight
Enter the percentage of available ductwork to system
capacity in each zone. Ex. Calculate nominal CFM for the
zone and divide by total system capacity. This can also be
used to set priority to a specific zone by giving it a larger
weight. Sum of zones does not need to equal 100%.

AH Stage-up
Threshold %
Air handler Stage-up threshold, Y2 output to Air Handler or
W2 to FF Furnace engaged when threshold % is reached
Set the percentage of ductwork you would want to be
open before the HeatPumPro panel will send a Y2 signal
to the air handler to increase capacity or W2 signal to
furnace to increase output capacity.

Heat Stage Threshold
Min leaving air temp (LAT) required for comfort at 30º F outside air
temperature (OAT). This set-point adjusts by 1
º for every 2º change
in OAT.
Sets the minimum supply air temp in the heating mode. At the
factory default the HeatPumPro will maintain a 88º supply air temp
at 30º F outdoor
temperature. The supply air temperature will raise
or lower a 1º F for every 2º F change in outdoor temperature.

Cool Stage Threshold Max cooling supply air temp, Y2 is energized if this LAT is not
reached with Y1 output
Sets the maximum supply air temperature allowable before
bringing on second stage cooling. Does not reset with OAT.

Set the outdoor temperature at which you want to lock the
heat pump out and have the fossil fuel back up to take over
on a call for heat. This setting is overridden by the “Heat
