Procedure for Setting a Time Program
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.
Time programs and time phases
Not valid for operation with a DHW tank with temperature
switch (such as an Aquastat).
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.
You can set up a time program for the following functions:
Function
Temperature level
Within the time phase
Outside the time phase
Central heating
A time program for central heating can be set at the room temperature controller (field supplied).
Operating instructions for room temperature controller
DHW heating
DHW heating is switched on.
The water in the DHW tank is heated
to the target DHW temperature.
DHW heating is switched off.
The time programs can be set individually to be the same,
or different, for every day of the week.
Setting time phases
Not valid for operation with a DHW tank with temperature
switch (such as an Aquastat).
You can set up to 4 time phases in each time program.
For each time phase, you select the start and end points.
Note:
DHW is not heated between the time phases.
Frost protection for the DHW tank is active if
no DHW tank with temperature switch is active.
When setting time programs, bear in mind that
your system needs some time to heat the DHW
tank to the required temperature.
Note:
With a “Combi boiler”, the “DHW comfort function”
is active during the set time phases (plate heat
exchanger is kept at temperature).
The time phases need to be deleted to switch off
the comfort function.
Example:
Time program for “Monday” for DHW
Time phase 1: 06:30 to 12:00
Time phase 2: 15:00 to 21:00
