Using the week program, you can set the water temperature for the days and times you wish.

If the appliance is running under a week program, then this is indicated on the display by the text PROG on the first line (see Figure 8.5). The second line shows the time of day, the day of the week and the temperature. The third line shows the next switching time of the week program and the programmed temperature. The fourth line shows the text PROGRAM ACTIVATED.

The appliance’s default week program switches the appliance on every day at 00:00 hours and off at 23:59 hours. The water temperature setting is standard 65°C.

If you wish, you can change every setting in the standard week program of the appliance.

If, while the week program is running, the water temperature becomes too low, then the appliance will run through the heating cycle (see ’7.4 The appliance’s heating cycle’), then return to the week program.

The following topics are covered in this paragraph:

•8.5.2 Starting up and shutting down the week program

•8.5.3 Changing the appliance’s standard week program

•8.5.4 Adding times to a week program

•8.5.5 Deleting times from a week program

8.5.2Starting up and shutting down the week program

The week program can be started up from any other operating mode, as follows:

•B: WEEK PROGRAM START OPERATION

Confirm with E.

A week program can be shut down simply by activating a different operating mode, for example “ON mode”.

8.5.3Changing the appliance’s standard week program

n Remark

First fill-in the desired week program on the program card supplied. See appendix ’A.3 Week program card’.

A week program is made up of a number of programmable periods in which you can have the appliance switch on and off. A period consists of:

•switch-on time: day of the week, and time in hours and minutes;

•switch-off time: in hours and minutes;

•the water temperature setting;

•on/off setting for a program-controlled pump.
