Holiday period:
Adjust the thermostat* to the holiday period. See
the user thermostat manual. The hot water facility
can be switched off by means of the program
button on the control panel.
Re-setting the central heating system:
Switch off the three program buttons ,
, when these are activated. Switch off the
power supply. When the boiler is being drained
one should take into account that a part of the
heating water will remain in the boiler. When risk
of frost arises one should take care that the
remaining central heating water in the boiler does
not freeze.
Holiday
* If you have a RS100
thermostat it is provided
with a holiday program.
The holiday period can be
adjusted on the thermostat
itself. The central heating
and DHW supply are
switched off during that
period. There is also the
option that only the central
heating is switched off. With
all of these possibilities the
frost protection system is
active.
The boiler will not function directly. The automatic de-aeration program of about
17 minutes will start after one of the three program buttons is pressed. The display
will show where A stands for Automatic de-aeration program Active and
the number on the right indicates the actual water temperature of the boiler.
Check the water pressure regularly and top up the installation when
necessary.
The working pressure of the installation should be between 16 and 18 PSI
It can take a while before all air has disappeared from a filled installation.
Especially in the first week noises can be heard which indicate the presence of
air. The automatic air vent in the boiler will remove the air, which means the water
pressure will reduce during this period and therefore topping up with water will
be necessary to adjust the flow water temperature
