HIGH PRESSURE FAULT
ISSUE
The refrigerant system’s high-pressure switch is showing as open.
RESOLUTION
Heat Only Units
Place heat pump in heating mode and perform the following troubleshooting.
Determine if an insufficient amount of water is being supplied to the equipment.
1. Confirm the filter pump is on.
2. If a multiple-speed filter pump is being used, run filter pump at a higher speed. Do not exceed the
maximum flow rate for the model.
3. Confirm water is not being diverted away from the heat pump.

Cool Only Units
Determine if an insufficient amount of air is being supplied to the equipment.
1. Check for proper fan operation. If the fan is not operating, contact AquaCal
®
Technical Support.
2. Check for obstructed airflow around the heat pump.

3. Check for a dirty or blocked evaporator coil.

HIGH WATER TEMPERATURE
ISSUE
Incoming water temperature has exceeded 110° F (43° C) and the unit has been deactivated. The heat
pump will not operate until the incoming water temperature drops to 100° F (38° C) or lower.
RESOLUTION
1. Determine if a gas heater is sending water directly to the heat pump. This situation would need to be
corrected before continuing.
2. If a solar heater is sending water directly to the heat pump, the water can initially be hotter than 110° F
(43° C). After the water from the solar panel normalizes, the fault will no longer display and the heat pump
will resume as needed.
3. If the
HIGH WATER TEMPERATURE
fault continues to display, the water temperature sensor may
require replacement.
