Electronic Control
with Diagnostics
In addition of controlling the temperature of the water, this electronic control informs you on
the operation of your pool heat pump or any faults that may arise by displaying codes on the
temperature display.
When the unit is in defrost mode, the code DEF is displayed on the temperature display.
This under normal conditions is not considered to be a fault.
Specific Functioning of your Reversible Electronic
Control with Diagnostics (XLR)
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 unit makes 4 consecutive cycles (heating
and defrost) within 1 hour, the unit goes into protection mode to avoid inefficient use of
electricity. These frequent defrost cycles mean that the conditions of ambient temperature
and humidity do not allow to heat your pool water.
temperature will be displayed alternately on the electronic control. Refer to the section
"Service Analyser Codes" to validate what you should do.

OPERATION OF YOUR POOL HEAT PUMP

Temperature Calibration

It is possible to have a temperature variation between the water in the swimming pool and
the reading of the pool heat pump temperature probe (sensor). Example: the water in the
pool is 26 ºC (80 ºF) and the pool heat pump electronic control displays 24 ºC (76 º F).
To calibrate this variation, perform the following procedure:
1. With the use of an accurate thermometer, read the pool water temperature (e.g.: 26 ˚C).
2. Read the temperature displayed on the pool heat pump electronic control (e.g.: 24 ˚C).
3. To determine the differential subtract the pool water temperature from the pool heat
pump displayed temperature, 26 - 24 = 2 ˚C. Therefore we must compensate for the 2 ˚C
variation.
4. Press BOTH the UP and DOWN arrow keys until the programmed temperature is
displayed (the temperature you have previously set) then release both buttons.
5. Press the ON/OFF button and release.
6. Using the UP or DOWN arrows, enter the calibration value, (2 ˚C). In this case, by
pressing the UP arrow twice.
7. After 5 seconds, when all the buttons have remained untouched, the display temperature
will show the pool water temperature as per your thermometer. If this is the case, the
calibration process was successful.
