If the display still does not illuminate, it is recommended that the heat pump installer or electrician confirm the
l
heat pump is receiving power.
2. Confirm correct mode is selected.
3. Confirm thermostat is set correctly.
When heating the water is desired, the thermostat should be set above the current water temperature.

controller's signal.
