The heater will stay on until the set temperature point is reached. When reached the heater will maintain
the pool temperature within 0.5°C differential.
3.7 Calibrate temperature
If for any reason the water temperature displayed by the controller is different to the water temperature in
the pool, adjust this by pressing and holding the dial button for five seconds. The display will show calibrate
and the actual temperature (see Fig. 16). Turn the dial clockwise to adjust it UP or anti clockwise to adjust
it DOWN.

NOTE:
The controller will allow maximum adjustments of ± 2°C
. If the controller displays ‘No flow’
message, then entering the calibration mode will not be possible.
Useful advice:
To reduce running costs and speed up the heating process, insulate the pool wherever possible. A floating
solar cover is an essential minimum to retain heat.
4. TROUBLE SHOOTING
➢
Quick Function Test
Observe the main
electricity meter when the heater is on (i.e. red light ‘On’) and then observe it again
when the heater is in the standby mode (i.e. amber light ‘On’). The test should show that the meter is
recording more electricity being used by the heater when the red
light is ‘On’. It is impossible for an electric
heater to waste energy, if it is drawing power then that power will be turned into heat that will be transferred
to the water.
➢
Accurate Function Test
If a more accurate test is required to confirm that your heater is delivering the specified heat output, two
electricity meter readings will need to be taken from the property’s main electricity meter, at one hourly
intervals (i.e. take one-meter reading and then a second reading exactly one hour later). By subtracting
the first reading from the second reading the number of units (kilo Watts kW) consumed can be calculated.
Note that your heater is also rated in kW hours.
The pool pump and heater will need to be running continuously during the test (i.e. with the heater red light
‘On’). To avoid inaccurate results when performing this test, it is important to refrain from using other high
current consuming appliances in the property, such as tumble dryers, showers, cookers etc. A large
domestic pool pump of one horsepower will draw less than 1-kW in a one-hour period. The conclusion of
the test should prove that for example a 6-kW heater and a half horsepower pump will draw between
6.3-kW to 6.5-kW in one hour.
