Pool/Spa Modes
The control is equipped with two independent thermostats, one for pool temperature and one for spa temperature.
This is to allow the user to preset a temperature of their choice and switch between the two settings.
To change between pool and spa modes,
 Press the SET button until the control reads P_S
 Press either arrow key to switch from POL to SPA
 Once the heating mode has been selected, it will be displayed for five seconds and then return to the actual
pool water temperature. The lights on the right side of the display indicate the selected mode.
ATTENTION! There is a 3 minute time delay upon initiation of a heating cycle. This is to ensure that the critical
components do not fail due to short cycling of the heater.
Displaying the Temperature in °F or °C
The heater comes preset from the factory displaying temperature in °F.
To change between °F or °C,
 Press the SET button until F_C is displayed
 Press either the UP or DOWN arrow keys until desired display setting is displayed.
 The control will return to the actual pool water temperature after five seconds in the mode chosen.
Changing the Set Point Temperature
To change the set point temperature, press the SET button until either POL or SPA is displayed. The programmed
temperature will be displayed. Press either the UP or DOWN arrows to change the set point temperature. After
adjusting to the desired temperature setting, the display will revert to the actual pool water temperature after five
seconds. The default factory setting is “OFF”.
Heater Operating Time
It is the owner’s responsibility to adequately set the pool pump run time to heat the pool. On colder days, the pool
pump run time will need to be extended. The heater requires longer run time in colder weather. The heater is
capable of running 24 hours per day if necessary. When you first run your heater, it may need to run continuously for
24 to 48 hours to get the pool up to the desired temperature. On warmer days the heater will not require as long of a
run time because there will be less heat loss from the pool.
Initial Startup
Before starting the heater for the first time, it is important to verify that the dedicated circuit breaker and/or the
service disconnect are in the “ON” position. Also make sure that the water is circulating freely through the heater and
that the pump is activated.
You will then need to set the water temperature to your desired set point. The heater will start after a three minute
time delay if the desired set point is higher than the actual pool water temperature.
Defrost Cycle
The heater is designed to enter the defrost cycle at ambient air temperatures below 48 Fahrenheit. During this cycle,
the unit may shut down and the control will display “FS” until the ambient air temperature rises above frosting
conditions.
Condensation and Drainage
Normal heat pump operation will result in water draining from the bottom of the heater. This is due to the evaporator
coil condensing water from the humid air. Condensate water will drain out through the drain holes located in the base
pan. Your heater typically produces 3 to 5 gallons of water per hour. When the heater is shut off for a period of time,
the water created from condensation will evaporate.
