ADJUSTING THE POOL WATER TEMPERATURE

Using the up and down buttons, you can set the swimming pool water to the desired temperature between +15°C up to + 65°C.

NOTE. WHEN PROCESSING FUNCTIONS F1-F5 IF NO ADJUSTMENTS ARE MADE FOR 5 SECONDS THE DISPLAY WILL REVERT BACK TO THE CURRENT & DESIRED WATER TEMPERATURE AS ABOVE

When the SET button is used for the first time, the display panel will display F1-this is to set the temperature differential. The recommended setting is 2°C. To adjust setting YOU MUST PRESS THE ON/OFF BUTTON FIRST. Then use the UP and DOWN button to set the differential temperature range between 0 °C ~ 5°. Press on/off button again to take you back to the normal display. The unit will now stop working when the swimming pool water temperature reaches the setting temperature. The unit will automatically restart when the swimming pool water temperature drops below the setting temperature. Eg. If current pool water temperature is 20°C, F1 has been set to 02 (heating mode) when the temperature reaches 20°C the heater will stop and restart when the water temperature is below 18°C.

When the SET button is pressed twice, the display panel will display

F2- the defrosting cycle. The recommended setting is 30 minutes. To adjust setting YOU MUST PRESS THE ON/OFF BUTTON FIRST. Then use the UP and DOWN buttons to adjust defrosting period between 30 minutes up to 99 minutes. Press on/off button again to take you back to the normal display. The unit will now start to defrost after the setting period when the defrosting sensor reaches the frosting condition.

When the SET button is pressed for the third time, the display panel will display F3 - the defrosting time. The recommended setting is 5 minutes.
