with "Red. set room temp." (room temperature for
reduced heating mode, night setback).
Your heating contractor can make further settings for
■
you during commissioning.

Terminology

The appendix contains a chapter entitled "Terminol-

functions of your boiler.
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 22).
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 23).
The operating program for central heating is auto-
matically set to "Standby mode" while the holiday
program is active.
– If, for an extended period, you neither want to heat
the interior nor do you require DHW, select the
"Standby mode" operating program for the rele-
vant heating circuits and for DHW.
– See page 21 for the relevant heating circuits
– See page 27 for DHW heating
■ Never set the DHW cylinder temperature excessively
high (see page 25).
Contact your heating contractor for additional energy
saving functions offered by your boiler control unit.
For general recommendations on energy savings, see
