Putting the unit into operation
Before putting the unit into operation make sure, that the
unit and the installation are well vented. Vent the gas
pipe and open the gas valve for the unit. The unit does
not require adjustment of burner pressure and air
quantity because it is self-adjusting and is factory-set at
the correct value.
9.1 Central Heating system
Provided there is a heat requirement from the
thermostat or control, the central heating program will
be put into operation by means of the
key (central
heating program). The circulation pump will start
circulating and the unit will start the burner.
9.2 Hot water supply
Provided there is a heat requirement from the boiler the
hot water program will be put into operation by means of
the
key (hot water program).
9.3 Adjustments
In the Control Tower a number of adjustments can be
made. These adjustments can be fed in easily by means
of the keys on the unit. However, a distinction is made
between adjustments which are done by the user and
adjustments done by the installer.
At users level adjustments can only be made from the
technical read-out in other words from the display read-
out with the operating function and the water
temperature. Adjustments can not be made from the
indication.
The next two chapters are accessible after pressing the
Mode key:
Chapter 1

read out or the technical
with the
read out.
Chapter 2
The chapter in which adjustments can be made.
