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 hea-
ting is required
Suddenly, there is no heating or hot
water; it is cold.
The room temperature setpoint re-
quires frequent adjustments becau-
se it is too cold or too hot
Today, I will be absent for several
hours during the day
I am travelling for a short period of
time (e.g. 3 days)
I will be travelling for an indefinite
period of time
In summer, it is too cold or too
warm.
Remedy
Set a higher value for the room temperature with and the
rotary pushbutton (see page 16).
Set a lower value for the room temperature with and the
rotary pushbutton (see page 16 and 20).
Set the operating mode to “HEATING” with (page 20).
Set the operating mode to “PARTY” with and set
the desired time (page 19).
Press for 3 seconds and set the additional loading time
(page 29).
Set operating mode to “SUMMER” with (heating
off, hot water only) (page 20).
Check the boiler controller for alarms and consult a heating en-
gineer, if necessary.
Change the set heating curve (page 27).
Changing the heating curve is not sensible if your system is fitted with
a room sensor (or room station) and an outdoor sensor. The correct
settings for the heating curve are then provided automatically
Set the operating mode to “ABSENT TIL” with and set
the return time (see page 19).
Set the operating mode to “HOLIDAY TIL” with and set
the return time (see page 19).
Set the operating mode to “RED. HEATING” with .
When returning, set the operating mode to “AUTOMATIC”
(see page 20).
indicates that the summer disconnection is active.
If it is too cold, set the operating mode to with (see
page 20).

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 mor-
ning and come back late in the
evening
You are travelling for an inde-
finite period of time and want
the living area to be at the
set reduced 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

Changing the time programs (heating times)
This function allows creating individual time programs for the heating and DHW modes. After selecting the
respective heating circuit, the factory-set standard program (P1) is loaded and can then be edited individu-
ally.
The standard heating times preset by the manufacturer are, e.g.:
Circuit Day Heating from
All heating circuits
(HC,MC-1,MC-2) Mo-Su 06.00 - 22.00
Domestic hot wa-
ter circuit (DHW) Mo-Su 05.00 - 22.00
Further standard programs can be - or could have been - set-up or enabled for programming by the
installer (P1-P3) see page 18.
