Temperature control system
The electronic temperature control system and the temperature sensor have been calibrated to
work correctly together. Recalibration must be performed if the sensor or the control unit is
replaced separately. If the displayed temperature does not match the actual water temperature
because the temperature sensor is fitted in an unsuitable position, it is possible to make an
adjustment for this difference. (Please see “Calibrating the temperature” on page 8).
The following table can be used for checking the temperature sensor.
Resistance values of the temperature sensor
Temperature Resistance
20°C 5800 Ohm
25°C 4600 Ohm
30°C 3700 Ohm
Connect the swimming-pool temperature sensor to terminals 15 and 16. The temperature
sensor is supplied as standard with a cable length of 1.5m. If required, this can be extended to a
maximum length of 20m using a 2-core cable (min. cross-section 1.5mm²).
Avoid running the sensor lead along with mains cables to prevent potential interference.
If a temperature sensor is not connected
or is faulty, a warning sign (warning
triangle) is displayed. There is no
temperature displayed in the touchscreen,
and the indicator light shows red.
Since precise temperature control can only be achieved with good heat transfer
between the temperature sensor and swimming pool water, an
R 1/2" thermowell
(part no. 3200200001) must be fitted in the piping system.
