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
T3; 9 °C in the example (see Figs. 1 and 2 in the
appendix)
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 equa-
ted with the heating output.
The heating output corresponds to approx. the
output of the heat source + 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 hea-
ting system.
>>> Right flashes when energy is being fed to the
heating system (e.g. only from the electric auxili-
ary heating).
The heat pump is in the CH mode. Moreover, the
heating flow temperature is displayed (in the ex-
ample 30 °C).
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 display-
ed.
