What to do if...
The following information can be used as a first level support in frequently occurring situations.
Observation
It is too cold
It is too warm
From now on, equal day and
night temperatures should be
maintained continuously
This evening, the heating should
remain on for longer
A larger amount of hot water is
required
From now on, hot water but no
heating is required
Suddenly, there is no heating or
hot water; it is cold.
The room temperature setpoint
requires frequent adjustments
because it is too cold or too hot
Today, I will be absent for sever-
al hours during the day
I am travelling for a short period
of time (e.g. 3 days)
I will be travelling for an indefi-
nite period of time
In summer, it is too cold or too
warm.

Holiday, absent, constant reduced heating
Depending on the duration of your absence and what your requirements are in regard to comfort, there are
different operating modes available for interrupting or reducing the heating. In any case you will be able to
save a lot of energy and money if the rooms are not heated or less heated during your absence.
The following table is intended as a guide for finding the best operating mode for each particular case:
Application
You go on holiday for e.g. 1
week and you know the return
date.
You leave home in the morning
and come back late in the eve-
ning.
You are travelling for an indefi-
nite period of time and want the
living area to be at the set red-
uced temperature on return.
You are away for an indefinite
period of time during spring or
autumn and you don’t mind if
your home is cool on return
