Display Of The Energy Consumption, Energy Yields And Efficiencies; Product Description; Product Design; Serial Number - Vaillant flexoTHERM exclusive VWF 57/4 Operating Instructions Manual

– With well water heat source: Ground
water module (5)
There is an opportunity for active cooling
to take place via circulation reversal for
the heat sources air, ground and ground
water.
Note
Approval from the water authorities
is required for operation with active
cooling using ground water as the
heat source.
3.2 Display of the energy
consumption, energy yields
and efficiencies
The product, the system control and the
app show approximate values for energy
consumption, energy yields and efficien-
cies, which are extrapolated based on cal-
culation algorithms.
The values that are displayed in the app
may differ from the other display options
due to staggered transfer intervals.
The determined values depend on:
– Installation and system of the heating
installation
– User behaviour
– Seasonal weather effects
– Various tolerances of unit-internal com-
ponents
The recording of the values only includes
the product in the factory-delivered condi-
tion. Supplementary accessories, even if
they are installed on the product, as well
as any other components in the heating
system and other external consumers, are
not part of the data recording.
Deviations between the determined values
and the actual values may be significant.
The determined values are therefore not
suitable for creating or comparing energy
billing, for example.
When replacing the PCB, the values for
energy consumption, energy yields and
0020213396_05 Operating instructions
efficiencies are reset in the heat pump's
control panel.
