DHW stor tank since maint (7091):
The time elapsed (in months) since the last
maintenance. If the value is greater than the setting
"DHW tank interval" (Line 7090), this symbol will be
displayed and a maintenance message will appear in
the Info section:

Emergency operation (7141):
Emergency operation can be activated and
deactivated manually.

Line no. Programming line
7150 Simulation outside temp
Simulation outside temp (7150):
To make the starting-up
processes easier, it is possible to simulate an outdoor
temperature in the range of -50...+50°C. During
simulation, the current, composite and attenuated
outdoor temperatures are ignored and substituted
with the adjusted simulation temperature.

with the available heaters (flow, storage tank, DHW
The tank). In this case the compressor will remain off.
Emergency operation function type (7142):
•
Manual:
Emergency operation can be activated/deactivated
only through the Emergency operation setting on line
7141.
•
Automatic:
As soon as a fault occurs on the heat pump,
emergency operation is automatically switched on. It
stops when the fault is removed and, if necessary,
cleared (reset). Emergency mode may however be
activated / deactivated manually via the "Emergency
operation" setting on line 7141.
Computation of the three outdoor temperatures
based on the actual outdoor temperature continues to
be performed during the simulation, and these
temperatures are available again when the simulation
is over.
This function can be deactivated by selecting -.- on
this line or automatically, after a 5 hour waiting
period.
