Operating the heating system

3.1

Switching on the heating system

Before switching on, ensure that:
– The operating pressure is high enough
– The fuel supply has been opened at the main shut-off
valve
– 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 rotary selectors on the control panel to
"AUT" (automatic mode). The programming unit
takes control of the panel in this setting.
Switch on the ON/OFF switch (position "1"). The con-
trol panel checks the current status of the system,
and the burner may start up.
When the boiler detects heat demand, the start program
begins and the burner fires after about 30 seconds. Heat
demand arises when the central heating or DHW tem-
perature falls below the set value. The LED below the
corresponding rotary selector will light up.
Check the following settings on the programming unit
and adjust as required:
– Automatic operating mode
– Desired room temperature
– Desired DHW temperature
– Desired heating program
USER NOTE
Information on operation, e.g. setting
the temperatures, can be found in the
documentation for the programming
unit.
