Connecting and Configuring a Solar Control System (Optional)
To support a direct connection to solar control systems, the AquaCal® heat pump must be equipped with an optional expansion board. This expansion board would need to be installed on the heat pump's main control board. The control board is located on the low-voltage side of the electrical enclosure. It will also be necessary to connect an actuator, roof sensor, and two additional water temperature sensors.
Please Note:
If the expansion board is not found, check with the installing dealer or manufacturer for availability.
