PENTAIR VS PUMP FAULT
ISSUE
The heat pump has either lost communication with a connected Pentair water pump. Or the Pentair
pump needs attention.
RESOLUTION
Check circulation pump documentation for a resolution for that product.
HIGH PRESSURE FAULT
ISSUE
The refrigerant system’s high-pressure switch is showing as open.
RESOLUTION
Heat and Cool Units (Reversing)
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.

HIGH WATER TEMP
ISSUE
Incoming water temperature has exceeded 108° F (42° 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 the
HIGH WATER TEMP
fault continues to display, the water temperature sensor may require
replacement.
HP5 SYSTEM LOCKOUT
ISSUE
The heat pump has locked due to five high-pressure faults during one call for heating or cooling.
RESOLUTION
1. Deactivate then reactivate power to the heat pump to clear error.
2. Troubleshoot the high-pressure issue causing the error.
