To Raise or Lower Desired Water Temperature

(Pool or Spa Mode)

The Multi function electronic control has the capability of memorizing two different 
programmed temperature settings as follows:

For POOL the maximum is 95°F (35°C) and for SPA the maximum is 104°F (40°C)

To access the pool 

(POL)

 mode or spa 

(SPA)

 mode, press the 

SET

 key until you see 

P-S

 

and then press the 

UP

 or 

DOWN

 key to switch to 

POL

 or 

SPA

.

Push the SET key again to enter into the desired heating temperature mode.

Press the UP or DOWN arrow to increase or decrease the temperature setting by one degree 
at a time. Once the heating mode is programmed, it will be displayed for approximately 5
seconds; then the temperature display will return to the actual pool water temperature. The 
light on the right side of the display indicates the chosen heating mode .

To change display from Farenheit to Celcius

1.  Press and release the SET key until 

F-C

 appears on the temperature display.

2. Whilst 

F-C

 is still on the display Press and release the 

UP

 or 

DOWN

 arrow key until C 

is displayed.

3.  Release all keys and the control will now be set for Celcius. (do not press any other keys
 

for 5 seconds)

To go back to Farenheit follow the same instructions above, however when you are at step 
2, F will need to be shown on the display before releasing all keys

Defrost for Electroheat SubZero

During the defrost cycle, the fan motor stops working and the hot gas is injected into the 
evaporator to melt the frost. However, when the pool heat pump makes 5 consecutive 
cycles (heating and defrost) in less than 15 minutes, the unit goes into protection mode to 
avoid inefficient use of electricity. These frequent defrost cycle’s mean that the conditions 
of ambient temperature and humidity do not allow to heat your pool water. The FS4 code 
will be displayed on the electronic control.  Refer to the section titled ¨ Service Analyser 
Codes ¨ to validate what you should do.
