5.5 Displays at user level
The individual displays on the operator control panel are
described and explained below.
Display shown Description
Graphics display (Top-level display)
You can read off the instantaneous state of the system from this dis-
play. This is always 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;
in the example 9 °C
Under the arrow the output of the heat source
(in the example 10 KW) is displayed.
The extent of darkening of the arrow graphically
shows the energy efficiency of the heat pump
under the given operating conditions.
The output of the heat source must not be
equated with the heating output.
The heating output corresponds to approx. the
output of the heat compressor output.
When the compressor or the electric auxiliary
heating 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 heat-
ing system.
>>> Right flashes when energy is being fed to the
heating system (e.g. only from the electric auxil-
iary heating).
The heat pump is in the CH mode. The heating
flow temperature is also displayed (30 °C shown
in example).
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 dis-
played.
Only if cooling is installed and the corresponding
settings have been made by the expert techni-
cian at the heat pump controller:
The symbol indicates that the heat pump is in
cooling operation. Under the symbol the actual
heating flow temperature is displayed
(in the example 20 °C).
