Altering The Switching Times; Calling Up The Switching Times - Viessmann Dekamatik-M1 Operating Instructions Manual

Altering the switching times

Set the switching times precisely for those
periods in which you require space heating
or DHW production.
This will reduce your heating bills.
You can program up to 4 activation periods
per day for room heating and domestic hot
water.
- Identical timer schedule for every day
of the week
The switching times can be set
separately for the boiler circuit
and for domestic hot water.
To do so, open the cover below
the display and follow the menu structure.
Refer to the menu structure (Overview 1
and 2) on page 8.
- Unique timer schedule for each day of
the week
First set the same switching times for
every day of the week (see above). Then
set the switching times for individual days.

Calling up the switching times

Open the cover below the display.
You can enter the same time program for
every day of the week or a different time
program for individual days. If you do not
enter individual switching times, the control
unit will operate in accordance with the
factory setting, i.e. room heating and
domestic hot water heating are in operation
from 6:00 to 22:00 HRS.
