4.6 Function displays
Basic display
A display with graphical symbols appears as the basic dis-
play . It shows the current state of the heat pump. If, when
setting values, you do not use either of the dials for 15 min-
utes, the basic display automatically reappears.
Outside temperature (here 10 °C).
Source inlet temperature of the heat
source; in the example 9 °C.
Under the arrow, the output of the
heat source is displayed (7 kW in the
example).
The extent of darkening of the arrow
graphically shows the energy effi-
ciency of the heat pump in the current
operating condition.
The output of the heat source must
not be equated with the heating out-
put.
The heating output corresponds ap-
proximately to the output of the
heat source plus the output of the
compressor.
When the external auxiliary heater
is switched on, the arrow is full and
flashes.
>>> flashes left and right when the
compressor is switched on and thermal
energy is consequently being taken
from the environment and fed to the
heating installation.
>>> flashes right when the heating
installation is being supplied with ther-
mal energy (e.g. only via the external
auxiliary heater).
The heat pump is in heating mode.
The heating flow temperature is also
displayed (in the example 30 °C).
The symbol indicates that the domes-
tic hot water cylinder is being heated
or that the heat pump is in stand-by.
The temperature in the domestic hot
water cylinder is also displayed (in the
example 30 °C).
