Switch on the boiler

▶ Put the on/off switch to position "1" ( figure 5, [1]).
3.5

Check water pressure

For the boiler to work efficiently, the normal water pressure must be
between 1.0 and 2.0 bar.
▶ Ask the installer whether a higher pressure is necessary.
▶ Read off the water pressure on the display ( Chapter 4.1, page 6).
▶ Top up the heating system if necessary ( Chapter 5.1, page 8).

3.6

Setting the maximum boiler temperature

▶ Set the maximum boiler temperature required in the setup menu
( Chapter 4.2).
The heating and DHW operations can be switched on and
off independently of one another.
3.7

Heating controller settings

Some of the functions described in this document change when
connecting a heating controller, i.e. room thermostat or weather-
compensated controls. The controls exchange parameters with the
boiler.
▶ You should therefore carefully read the operating instructions for the
corresponding heating controls.
