Commissioning and matching up of the control unit to
local conditions and the structural characteristics of the
building must be carried out by your heating contractor.
Installation and service instructions
As the user, you may be obliged to notify your local
flue gas inspector of the installation of new combustion
equipment [check local regulations]. Your local flue gas
inspector (where applicable) will also provide you with
information on additional tasks concerning your com-
bustion equipment (e.g. regular testing, cleaning, etc.).

■
For central heating, select the operating program
that meets your current requirements:
–
For short periods of absence (a few hours, such as
for shopping trips), select
"Economy mode"
(see
page 26).
The room temperature is reduced for as long as
economy mode is activated.
–
If you are going away, select the
"Holiday pro-
gram"
(see page 26).
The operating program for central heating is auto-
matically set to
"Standby mode"
while the holiday
program is active.
–
If you do not want to heat the rooms and you do
not require DHW for an extended period, select the
"Standby mode"
operating program for the rele-
vant heating circuits and for DHW.
–
See page 24 for the relevant heating circuits
–
See page 29 for DHW heating

Never set the DHW cylinder temperature excessively
high (see page 28).
