1.5 Connecting Multiple Heat Pumps (Optional)

Up to 16 heat pumps can be connected and controlled from a primary heat pump.
There are two reasons for using a multiple heat pump configuration:
1. Controlling multiple heat pumps from one location; the primary heat pump.
2. Preventing heat pumps from starting up at the same time and causing an excessive power
draw on the electric circuit.
NOTICE
The wire size connecting the heat pumps must be 22-gauge, 2-conductor,
l
low-voltage wire. Be sure that the size of the wire will allow at least two
wires per connection point.
Do not attempt to connect heat pump equipment in multiple configurations
l
with previous HP7 and HP7R versions of the control board. See Figure 7.
No onboard port is provided for heat pumps with these control board
versions. An Automatic Sequencing Controller (ASC) accessory is
required for those types of heat pumps.
