Holiday period:
Adjust the thermostat to the holiday period. See
the BrainQ user 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.
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
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.
