Heat Pump Is Running, Not Heating
ISSUE
The heat pump is running. But the water is not heating.
RESOLUTION
1. If the heat pump is using an external controller, confirm it is set correctly.
l
Contact the installer of the device or the device’s manufacturer for further assistance.
2. Confirm heat pump mode is set to heat.
3. Confirm thermostat is set to the desired water temperature.
4. Confirm valves are positioned to heat the correct body of water (either the pool or the spa). If heating a
spa that overflows into a pool, confirm the spa is isolated when being heated (not flowing into the
pool).
5. Confirm heat pump is transferring heat into the water.
l
Measure the pool-side and source-side discharge water coming out of the heat pump.
l
See " Adjusting Water Flow Using ΔT (Delta-T) " on page 15.
6. If an error code is displayed, diagnose and correct cause of code.
l
See " Fault Codes " on page 63.
7. Confirm that the filter pump has a sufficient run-time. The heat pump will not run (or heat the
water) without water flow.
l
See " Heating Recommendations " on page 76.
8. If heating a spa, deactivate air blower or venturi (if equipped) to allow for quicker heating times. For
pools, deactivate water features, such as slides, waterfalls, or fountains to allow water to retain heat.
Use of a liquid pool blanket product, such as an Aqua Blanket
™ , can also compensate for excessive
heat loss.

See " Liquid Blankets " on page 77.
Heat Pump Is Running, Not Cooling
ISSUE
The heat pump is running. But the water is not cooling.
RESOLUTION
1. If the heat pump is using an external controller, confirm the heat pump is programmed properly to
allow for cooling.
2. Confirm the heat pump mode is set to cool.
3. Confirm the thermostat is set below the current water temperature.
4. Confirm valves are positioned to cool the correct body of water (either the pool or the spa). If cooling a
spa that overflows into a pool, confirm the spa is isolated when being cooled (not flowing into the
pool).
5. If an error code is displayed, determine and correct the condition causing the code.
l
See " Fault Codes " on page 63.
6. Confirm heat pump is transferring heat out of the water.
l
Measure the temperature of source-side and pool-side discharge water coming out of the heat pump.
l
See " Adjusting Water Flow Using ΔT (Delta-T) " on page 15.
7. Confirm that the filter pump has a sufficient run-time. The heat pump will not run (or cool the
water) without water flow.
