5.4.3 "Time program" menu
In this menu the time programs can be set individually for the heating and DHW modes.
The P1 standard program set at the factory (also P2 and P3, if enabled) for each heating or DHW circuit
can be overwritten with individual switching times and temperature values. This is particularly useful if
specific personalized heating programs are to be created in case of periodically recurring events with
varying times (e.g. work shifts, etc.).
For the programming of timeprograms a maximum of three heating cycles with a switch-on and switch-off
time each is available for each weekday. Each heating cycle can also be combined with a freely selectable
temperature setpoint.
Caution: The standard programs are not lost if they are overwritten with personalized
programs. Personalized programs will be deleted if the standard program is reloaded
and hence need to be created again. For this reason the personalized switch-on and
switch-off times as well as the temperature values should be entered in the tables
envisaged for this purpose.
Entry: see menu selection level (Page 5-20)
5.4.3.1 Control Circuit Selection
After accessing the time program menu, the desired control circuits can be selected
using the rotary pushbutton in the following sequence
- Unmixed circuit (HC)
- Mixed circuit 1 (MC-1)
- Mixed circuit 2 (MC-2)
- Domestic hot water circuit (DHW)
Access to the selected circuit is carried out by pressing the rotary pushbutton.
5.4.3.2 Program Selection
If time programs P2 and P3 are enabled (see "System parameter menu time program
= P1 – P3), the program selection appears.
If time programs P2 and P3 are disabled ("System parameter menu time program =
P1"), the program selection is skipped automatically.
5.4.3.3 Weekday and Cycle Selection
After selecting the program the first cycle of the first weekday (MO-1) appears as well
as the relevant section flashing in the upper time bar. The other cycles are set by
turning the rotary pushbutton clockwise in crescent order according to the cycles and
week day (e.g. MO-1, MO-2, MO-3, TU-1, TU-2, TU-3, etc.), while after setting these
are to be selected by turning the rotary pushbutton counter-clockwise and confirmed
by pressing the rotary pushbutton.
