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:if the water in the pool is 26º C (80º F) and the heat pump electronic
control displays 24ºC (76º 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 (eg:
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 and 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.
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 Ultra

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.

Protection Devices

The integrity and performance of your pool heat pump and its components are protected
by internal safety controls. In normal use, your Waterco unit should never reach the thermal
protection level. However, if it should happen, you should identify the stated code on the
temparature display and refer to Service Analyser codes.

Codes

If a code appears on the electronic control refer to Service Analyser codes (all standard
models) on page 29.
