NOTICE
Failure to heed the following may result in damage to equipment.
l
The wire size connecting the heat pumps must be 22-gauge, 2-conductor,
low-voltage wire. Be sure that the size of the wire will allow at least two
wires per connection point.
l
Do not attempt to connect heat pump equipment in multiple configurations
with previous HP7 and HP7R versions of the microprocessor. See
Figure 7.
No onboard port is provided for heat pumps with these microprocessor
versions. An Automatic Sequencing Controller (ASC) accessory is required
for those types of heat pumps.
DO NOT CONNECT
HP7 or HP7R boards

1. Choose one unit to be the lead (or primary) unit. This is typically a
unit that can be accessed easily when temperature adjustments are
needed.
l
Note - The primary unit can be connected to an external
controller via the "smart bus" (PORT B) connection point if
desired.
2. Deactivate power to heat pumps.
3. Remove electrical access panels.
4. Route 22-gauge, 2-conductor, low-voltage wires to the low voltage
sides of the electrical enclosures. Follow all National Electric Codes
(NEC) and / or State and Local guidelines.
5. Connect the first secondary heat pump's wires to the unit selected as
the primary heat pump's.
6. Use "Port C" on the control boards as indicated. Connecting the "Y" to the "Y" and the "B" to the "B" on each
heat pump's port "C" connection point. The "G" and "R' connection points are not used. See Figure 8.
7. Connect any additional heat pumps as indicated, doubling up the wires as shown. See Figure 9. Confirm the same
color wires connect to the same wires on each heat pump ("Y" to "Y" and "B" to "B"). Up to 16 heat pumps can
be controlled by one heat pump.
8. Label the heat pumps appropriately as a primary unit and secondary units (Primary, Secondary 01, Secondary 02,
etc.) to simplify configuration and future operation.
9. Reattach access panels.

10. Apply power to primary heat pump.
Confirm the mode is set to "
SYSTEM
OFF ".
11. Apply power to the next heat pump and
confirm the mode is set to " SYSTEM
OFF
". Do this for each heat pump.
12. Program heat pumps with assigned
addresses. See " Configuring Multiple Heat
Pumps " on the facing page.
