Switching on the system
3 Switching on the System
Start-up
: Your heating contractor has installed and started
up your system. S/he should also have explained to you
how to operate the system.
Resuming operation
: If you want to start up the heating
system after an extended period of standstill, observe the
following instructions:
Switch on the system
Main switch
1. Check that the system is filled and bled of air in accor-
dance with regulations.
2. Ensure that the gas and oil valve on the supply line to
the boiler is open.
3. Switch on the boiler. Consult the operating instructions
for the boiler to ascertain the start-up procedure.
4. Switch on the system controller using the main switch
next to the control board (
figure on right
). The function
overview menu is called up approx. 30 seconds after
the version display. If the switch does not light up, the
power supply has probably been interrupted by the
emergency stop switch, which is usually next to the
boiler or (outside) on the heating room door.
5. Please always check whether the time and date have
been set correctly. Set the time and date if necessary
(
page 12
).
If the boiler does not start immediately, check that there is
a heating requirement at the controller. There are two main
reasons for a missing heating requirement:
1. The storage tank is at the set temperature.
2. There is no heating or hot water requirement.
In both cases, the boiler remains switched off.
A heating requirement is indicated by Output 12 being
highlighted in black (
see figure on right
). In this case, the
boiler should start up automatically after a while. The hot
water or heating buffer in the storage tank (
page 6
) is then
heated and supplies the heat consumers. If the tempera-
ture in the heating buffer exceeds the target value, the
burner is switched off.

Output 12 is highlighted in black
