Tips on Saving Energy

Vitotronic 200-H, HK1B Operating
Utilize the setting options for the control unit and remote
control (if installed):
H Never overheat your rooms. Every degree by which
the room temperature is reduced saves up to 6%
on heating costs.
Never set your room temperature higher than 68° F
(20° C) (see page 14).
H Never set the DHW temperature too high (see page 20).
H Only activate the DHW circulation pump at times when
DHW is drawn off.
Set the time program for this (see page 15).
H Select the heating program that meets your current
requirements:
– For short absences (e.g. shopping trips), select
"Economy mode" (see page 18).
As long as economy mode is activated, the room
temperature is reduced.
– If you are going away, set the "Holiday program"
(see page 18).
As long as the holiday program is activated, the room
temperature is reduced and DHW heating is off.
– In summer, if you don't want to heat any rooms but
do need DHW, select the heating program "Only
DHW" (see page 17).
In conjunction with a solar thermal system:
DHW heating is set at the factory to start at 05:30 h.
On sunny days, the DHW tank receives sufficient
heat from the solar thermal system so that the DHW
temperature is still high enough the next morning.
You can program DHW heating to start at 10:00 h,
for example.
- If you don't want to heat the rooms and you don't
require DHW for an extended period, select the heating
program "Standby mode" (see page 12).
Contact your heating contractor for additional energy
saving functions offered by the control unit.
Further recommendations:
H Correct ventilation/airing.
Briefly open windows fully and at the same time close
the thermostatic valves.
H Close roller shutters (if installed) at dusk.
H Set thermostatic valves correctly.
H Never cover radiators or thermostatic valves.
H Controlled DHW consumption: A shower generally
uses less energy than a full bath.
