Time Programs
Procedure for Setting a Time Program
Time programs and time phases
In the time programs you determine what your heating
system should do at what time. To do so, divide the
day into sections. These are called time phases.
Different temperature levels are active within and outside
these time phases.
The procedure is explained using the example of central
heating for heating circuit 1 in weather-compensated
operation.
You can set up to 4 time phases in each “Time program”.
For each time phase, you define the start point “Start”
and the end point “End”.
You can set up a time program for the following functions:
Function
Temperature level
Within the time phase
Outside the time phase
Central heating
Weather-compensated operation:
Your rooms are heated to standard
room temperature or comfort room
temperature.
Your rooms are heated to reduced
room temperature.
Constant operation:
Your rooms are heated with standard
supply temperature or comfort supply
temperature.
Your rooms are heated with
reduced supply temperature.
DHW heating
Note:
Not valid for systems with a
DHW tank with temperature switch
(such as an Aquastat).
DHW heating is switched on.
The water in the DHW tank is heated
to the target DHW temperature.
DHW heating is switched off.
DHW recirculation pump
The DHW recirculation pump is
switched on.
The DHW recirculation pump is
switched off.
The time programs can be set individually to be the
same, or different, for every day of the week.
In the main menu, you can check the time programs
under
“Information”: See page 32 onwards.
The bars in the time diagram are adjusted.
Example:
“Time program” for “Monday” for “Heating circuit 1”
Time phase 1:
06:30 to 12:00 with standard room temperature
Time phase 2:
15:00 to 20:00 with comfort room temperature
In between these time phases the system heats to
a reduced temperature.
Tap the following buttons:
1. “Heating circuit 1
“ in the menu bar
2.
3. “
Mo
”
4.
5.
for the “Start” and “End” of time phase 1.
The bar in the time diagram is adjusted.
6. “ Standard” to select standard room temperature.
7. to add time phase 2.
8.
for the “Start” and “End” of time phase 2.
9. “Comfort” to select comfort room temperature.
10.
to confirm
11. to exit the “Time program”.
Setting time phases
Note:
DHW is not heated between the time phases.
Frost protection for the DHW tank is active.
When setting time programs, bear in mind that
your system needs some time to heat the DHW
tank to the required temperature.
The following explains how to input the settings for a
time program. The specifics of the individual time
programs can be found in the relevant chapters.
