8.7 Displays in the operator level
Display shown Description
Graphics display (Top-level display)
You can read off the instantaneous state of the system from this dis-
play. This will always be shown if you have not actuated either of the
dials for a long time while another display is showing.
Outside temperature (here 10 °C)
Source inlet temperature: temperature sensor T3;
9 °C in the example (see Figs. 1 and 2 in the appen-
dix)
The output of the heat source is displayed under
the arrow (10 kW in the example).
The degree of darkening of the arrow provides a
graphical representation of the energy efficiency
of the pump under the specified operating condi-
tions.
The output of the heat source should not be equat-
ed with the heating output.
The heating output corresponds approximately
with the output of the heat the compres-
sor output
When the compressor or the electric auxiliary heat-
ing is switched on, the arrow is shown filled.
>>> Left and right flash when the compressor is
switched on and energy is consequently being
taken from the environment and fed to the heating
system.
>>> Right flashes when energy is being supplied to
the heating system (e.g. only from the electric aux-
iliary heating).
The heat pump is in the CH mode. The heating flow
temperature is also displayed (30 °C in the exam-
ple).
The symbol indicates that the domestic hot water
cylinder is being heated or that the heat pump is in
the ready state. The temperature in the domestic
hot water cylinder is also displayed.
This symbol indicates that the heat pump is in cool-
ing mode. The current heating flow temperature is
displayed below the symbol (20 °C in the example).
Note :
Cooling mode is only possible when using the VWZ
NC 14/17 accessory, and only for VWS 14 and
VWS 17 heat pumps.
