Setting the time program

You can set these heating times by
adjusting the time program for the heat-
ing water buffer cylinder. During the time
phases set, the heat-up condition of the
heating water buffer cylinder has an
effect on the operation of the boiler.
■ The time program for the heating water
buffer cylinder is made up of time pha-
ses. A time phase from 06:00 to 22:00
h every day is set at the factory.
■ The time program for the heating water
buffer cylinder is preset to Automatic
mode at the factory. In automatic
mode, the time program for the heating
water buffer cylinder is disregarded.
■ If you don't require automatic mode,
you can select up to 4 individual time
phases per day. For each time phase
you select the start and end points.
