Recurring emissions tests
■ Your heating contractor must prepare the boiler for
this test.
Notify your heating contractor approx. 2 weeks prior
■
to the next emissions test being due.
■ Ensure that suitable fuel in line with the operating
instructions is available.

Your system has been preset

Your boiler's control unit is set at the factory.
■ The heating circuits are set to the "Heating" operat-
ing program.
The domestic hot water heating is set to the "DHW"
■

Your heating system is therefore ready for operation:
Central heating
■ From 06:00 to 22:00 h your rooms are heated to
22 °C "Set room temp" (standard heating mode).
From 22:00 to 06:00 h, your rooms will be heated to
■
"Set red room temp" (room temperature for
reduced heating mode, night setback).
■ Your heating contractor can make further settings for
you during commissioning.
You can change any settings at any time to suit your
individual requirements (see from page 17).

Energy saving tips

Use the adjustment options offered by your boiler con-
trol unit:
■ For central heating, select the operating program
that meets your current requirements:
For short periods of absence (a few hours, such as
–
shopping trips), select "Economy mode" (see
page 23).
The room temperature is reduced for as long as
economy mode is active.
– If you are going away, set the "Holiday program"
(see page 24).
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, set the
"Standby mode" operating program for the rele-
vant heating circuits and for DHW.
– See page 18 for the relevant heating circuits
– See page 26 for DHW heating
■ Never set the DHW cylinder temperature excessively
high (see page 26).
