Procedure for setting a time program

Time programs and time phases

In the time programs you determine what your heat
pump should do at what time. To do so, divide the day
into sections. These are called time phases. Inside
and outside these time phases. The system behaves
differently in accordance with the following table.
You can set up a time program for the following functions:
Function
Room heating
Room cooling
DHW heating
DHW circulation
pump
Quieter operation
■ 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 onwards.

Setting time phases

The procedure is explained using the example of room
heating for heating/cooling circuit 1.
You can set up to 4 time phases in each "Time pro-
gram".
For each time phase, you define the start point "Start"
and the end point "End".
Example:
"Time program" for the weekday "Monday" for heat-
ing/cooling circuit 1
Time phase 1:
■
06:45 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.
