Saving tips
Your installation produces heat and hot water. This oc-
curs via the control settings you made.
Factors that affect the energy consumption are, for ex-
ample, indoor temperature, hot water consumption, the
insulation level of the house and whether the house has
many large window surfaces. The position of the house,
e.g. wind exposure is also an affecting factor.
Also remember:
• Open the thermostat valves completely (except in
rooms where you want it to be cooler). The thermo-
stats slow the flow in the heating system, which
VVM S320 wants to compensate by increasing the
temperature. It will then work harder and consume
more energy.
• You can lower the operating cost when away from
the house by scheduling selected parts of the system.
This is done in menu 6 - "Scheduling".
• If you select "Hot water demand Small", less energy
is used.
