3.4.7 Switching time program
Various different timer programmes are available, that are set in
the factory, but which can be adjusted to suit, to provide conven-
ient and individual room and hot water temperature control.
The timer programmes regulate the associated heating circuit,
the storage tank charging circuit and an option connected circu-
lation pump in accordance with the stipulated switching times.
Adjustment
In the rotary switch position we set the time intervals for
the heating circuit, the integrated hot water generation and the
optional circulation pump.
● Place the rotary switch in the
"Time Program"
position.

An overview is displayed.
● Select the timer programme to be set with the rotary switch.
● Confirm the changes with a brief push of the rotary switch.

Settings are displayed.
● Select and change the value to be set with the rotary switch.
● Confirm the changes with a brief push of the rotary switch.
More detailed explanations and possible setting values for this rotary switch setting
can be seen in chapter 6 "Parameter settings".
Permanent timer programmes
For the connected heating circuits and the storage tank charging
circuit, timer programmes regulate the heating circuit tempera-
tures or the operating times for the circulation pump in ac-
cordance with the stipulated switching cycles. The switching
cycles are saved in time blocks for which various different set
temperatures apply.
In the switching cycles the heating system is regulated differen-
tiated into day and economy mode.
The temperature settings for this timer programme are carried out
via the set value settings
"Set Temp Day" , "Set Temp
Night" and "DHW Set Temp"
.
The following switching time programmes are available:
– 2 timer programmes for the heating circuit, each with 3

possible time cycles
– [HC Program 1]
– [HC Program 2]
A separate input for each individual day of the week is
possible, or in blocks of "Monday to Friday", "Saturday
to Sunday" and "Monday to Sunday".

Tab. 3-6 Menu structure heating circuit timer programme
Time settings for one switching cycle in one weekday or
block programme are also adopted for other time

periods, provided that they affect the same weekdays.
Examples referring to tab. 3-6:
a) For the single working day "Monday" the start time
in the 1st Switching cycle changed from 06:00 to
05:00.

In the time period "Working week" and "Entire
week", the 1st time block Switching cycle also
changed from 06:00 to 05:00.
b) For the time period "Weekend", the start time in the
1st Switching cycle changed from 07:00 to 08:00.

In the individual weekdays "Saturday" and

"Sunday", the 1st time block is automatically
Switching cycle also changed from 07:00 to
08:00.
c) For the time period "Entire week", the end time in
the 1st time block Switching cycle changed from
22:00 to 21:30.

In all the weekdays the 1st switching cycle is
also changed from 22:00 to 21:30.
– 2 timer programmes for the hot water circuit, each with 3 pos-
sible switching cycles
– [DHW Program 1]
– [DHW Program 2]
The setting and input structure of the timer programmes
are identical to the ones for the heating circuit timer pro-
gramme (see also tab. 3-6).
– 1 timer programme for one optionally connected circula-
tion pump with 3 individual possible switching cycles
[Circulation Time]
The setting and input structure of the timer programmes
are identical to the ones for the heating circuit timer pro-
gramme (see also tab. 3-6).
For further instructions concerning settings for an op-
tional circulation pump, see section 3.6.8.
Saved switching time programmes can be changed at any time.
To provide a better overview, we recommend making a record of
the programmed switching times and keeping it in a safe place
(see chapter 10.1.1).
The permanent timer programmes are preset as per tab. 3-7.
