Controls
Your heat pump pool heater incorporates digital safety
controls and indicators to ensure its safe, reliable
operation.
Water 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.
Operating Instructions
The electronic board has the capability of memorizing
two different programmed temperature settings as fol-
lows (refer to Fig. 5):
•
For a pool, maximum 95°F (35°C)
•
For a spa, maximum 104°F (40°C)

DOWN arrow to decrease the temperature setting one
degree at a time.
Once the control has been programmed to the desired
pool water temperature, the programmed temperature
will be displayed for approximately 5 seconds. Then
the digital display will display the actual pool water

WARNING:
Install a check valve and/or a Hartford
loop AFTER the heat pump pool heater and
BEFORE any chlorinating devices. Install any auto-
matic chemical feeders AFTER the heat pump pool
heater.
Improper installation of any type of auto-
matic chemical feeders can result in serious
damage to, or premature failure of, the heat
pump pool heater and will void the heat pump
pool heater warranty.
