Main menu gis

The display now shows the menu for the week program, see Figure 8.7. With the default setting, the program switches on and off every day at 00:00 and 23:59 hours respectively, the water temperature is 65ºc and the pump is switched on (P).

Example

As an example, we will set the switch-on time for Sunday to 08:15 hours, and the matching switch-off time to 12:45 hours. The water temperature will be set to 75ºC and the pump will run continuously.

The following settings are entered one by one via the menu: the switch-on time, the switch-off time, the desired water temperature, and the state of the program- controlled pump.
