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.

Setting the switch-on time

2.Bring the cursor to SU and press E. The sub-menu shown in Figure 8.8 will appear. The day indicated by the » will blink.

3.Use Hand Lto select the day desired. In the example, this is SU (Sunday). Confirm with E.

The cursor moves to the hour digits, which will blink. See Figure 8.9.

4.Use Hand Lto select the hour. In the example this is 08. Confirm with E.

The cursor moves to the minute digits, which will blink. See Figure 8.10.

nRemark

Because the switch-off time can never be earlier than the switch-on time, the switch-off time setting is automatically adjusted with the switch-on time.

5.Use Hand Lto select the minutes. In the example this is 15. Confirm with E.

The cursor moves to the switch-off hour digits, which will blink. See Figure 8.11.
