Starting
1. Start the pool water circulation pump.
Check that the water is circulating normally in the installation before switching on the heater. The heater must be completely
full of water before the power is switched on.
2. Switch on the power to the heater.
3. Set the desired pool temperature.
4. Check the flow switch by turning off the flow of water through the heater with a shut-off valve. The contactor should trip.
5. Turn on the water. The contactor should now close (after 15 sec.).
6. The heater will now heat the pool water to the desired temperature.
Setting the temperature
Press once (on the blue or red arrow key) - the display starts to flash and the set temperature is displayed.
Change the temperature up and down with the arrow keys until the required temperature is set.
Red = warmer, blue = colder in steps of 0,5°C.
After the setting is completed, the display will return to showing the actual pool temperature with
a fixed light.
Operation
For the heater to work, the pool water must be circulating.
The yellow LED marked "Heating" is lit when the heater is working and goes out when the correct temperature has been reached.
The display constantly shows the current temperature of the water. The set temperature can be changed at any time (see Setting
the temperature). To see the set temperature, press once
(the display flashes). NOTE: The set temperature is retained in the
memory after a power failure.
NOTE: Always switch off the power to the heater before
backwashing and before cleaning the filter.
