5.2.3.2 Setting time periods for days and blocks
For each day and block, you can set up to three time peri-
ods.
The time periods set for a day have priority over the time
periods set for a block.
Desired temperature Day: 21 °C
Desired temperature Night: 16 °C
Time period 1: 06.00 - 08.00
Time period 2: 16.30 - 18.00
Time period 3: 20.00 - 22.30
Within the time periods, the controller brings the room tem-
perature to the set desired Day temperature (Comfort mode).
Outside the time period, the controller brings the room tem-
perature to the set desired Set-back temperature (Set-back
mode).
5.2.3.3 Setting time programmes quickly
If, for example, you require a different time period for just
one working day in the week, first set the times for the entire
block Monday - Friday". Then set the different time period
for the working day.

sage appears on the display which informs you about differ-
ent periods. You do not need to adjust the times.

the display.
5.2.3.5 For the heating circuit
Menu → Time programmes → HEATING 1 and, where re-
quired, HEATING 2
–
The time programmes are only effective in the Auto-
matic mode (→ Page 18). In each set time period, the
desired temperature that you set in the Desired tem-
peratures function applies. Within the time period, the
controller switches to Comfort mode and the heating cir-
cuit heats the connected rooms up to the desired Day
temperature. Outside that time period, the controller
switches to the operating mode that the competent per-
son has set: Frost protection, Eco or Night temperature.
Set the time period for the heating circuit so that each time
period:
–
starts approx. 30 minutes before the time at which the
rooms should reach the desired Day temperature.
–
ends approx. 30 minutes before the time at which the
rooms should reach the desired Set-back temperature.

Menu → Time programmes → Heating circuit 1: Cooling
and, where required, Heating circuit 2: Cooling
–
The time programmes are effective in Cooling mode and
in the Manual cooling advanced functions. In each set
time period, the desired temperature that you set in the
Desired temperatures function applies. Within the time
period, the heating circuit cools the living rooms to the
desired Day cooling temperature. The heating circuit is
not cooled outside of this time period.
Individual dates vary from
the selected time programme
Mo-Su.

Note
The competent person can set a pre-heat time
and a pre-switch-off time for the heating circuit,
so that you can set the time period for the desired
Day and Set-back temperatures exactly to the
times at which the room temperature should reach
the desired temperature. Ask the competent per-
son whether he has set a pre-heat time or a pre-
switch-off time.
