Switching on the heating system

Before switching the system on, check
– that the operating pressure is high enough,
– that the fuel supply at the main shut-off valve is open
and
– that the heating system emergency stop switch is
switched on.
3.1.1 Starting the heating system via the control
panel and programming unit
Set both dials on the control panel to "AUT"
(automatic mode). In this setting, the programming
unit takes over control.
Switch the ON/OFF switch ON (position "1"). The
control panel checks the current system status and
the burner starts if required.
If the boiler detects a heat demand, the start program
commences and approx. 30 seconds later the burner
fires up. A heat demand is triggered if the heating or
DHW temperature falls below its set value. The LED
below the relevant dial illuminates.
Check and make sure the following settings on the
programming unit are set:
– Automatic operating mode
– Required room temperature
– Required DHW temperature
– Required heating program
USER NOTE
Operating instructions, for example
how to set temperatures, can be found
in the
documentation.
