Controls

our heat pump pool heater incorporates digital safety

controls and indicators to ensure its safe, reliable

operation.

ater Pressure Switch: Prevents operation when the

pump is OFF. The unit requires 5 psi minimum pres-

sure.

Digital Water Temperature Control: The pool water

temperature is controlled by the heat pump pool

heater’s digital control system, which gives you the

option of two settings: one for the desired spa temper-

ature and the other for the desired pool temperature.

Additionally, as mentioned earlier, the unit is compati-

ble with most ‘2-wire’ and ‘3-wire’ control/automation

systems.

Defrost Sensor: Prevents unit operation if ambient air

temperature falls below a predetermined safe mini-

mum (approximately 42°–48°F (5.5°–8.8°C), based on

humidity). The compressor will shut OFF but the fan

will continue to run.

Delay Timer: Prevents compressor from short cycling,

which could damage or destroy the hermetic

motor/compressor. Upon water temperature control

satisfaction, or other circuit interruptions, this solid

state device will prevent compressor restart for

approximately 5 minutes.
