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 key
on the control panel.
Re-setting the central heating system:
Switch off the three program keys
,
,
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.
The boiler will not function directly. The automatic de-aeration programm of about
17 minutes will start after one of the three programm keys is pressed. The display
will show
where A stand s for Automatic de-aeration programm 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 neces-
sary.
The working pressure of the installation should be between 1.5 and 1.7 bar
It can take a while before all air has dis-appeared from a filled installation. Es-
pecially in the first week noises can be heard which indicate the presence of air.
The automatic air vent in the boiler will make this air disappear, 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
Turning the boiler off
Holiday
The ATAG BrainQ room
thermostaat is provided
with a holiday programm.
The holiday period can be
adjusted on the thermostat
itself. The central heating
and DHW supply are swit-
ched off during that period.
There is also the option
that only the central hea-
ting is switched off. With
all of these possibilities the
frost protection system is
active.
