Maintenance
Maintenance functions can be used as a preventive
step for periodically
All maintenance functions can be individually activated
/ deactivated.
The controller automatically generates maintenance
messages if the settings defi ned are either exceeded or
fail to be reached.

7073 Cur starts compressor 1/hrs run
HP interval
Defi nes the maintenance frequency (in months) for the
heat pump.
HP time since maint
Displays the time (months) elapsed since the last
maintenance. If the value exceeds the "heat pump
interval" setting (Line 7070), the symbol
displayed and a maintenance message will appear in
the Info section:
17: Heat pump maintenance Interval (Priority 6)
This setting can be reset with the associated rights of
access.
Cur starts compressor 1/hrs run
The average number of compressor startups per hour
of operation, obtained over a period of 6 weeks.
If the value exceeds the "Comp1 max startups/hr op"
adjusted setting, the symbol will be displayed and a
maintenance message will appear in the Info section:
8: Too many compressor 1 startups (Priority 9)
This setting can be reset with the associated rights of

Emergency mode
If the heat pump is not operating properly, a emergency
service can be maintained. The emergency mode
enables the installation to be run with the available
heaters (fl ow, storage tank, DHW tank). In this case the
compressor will remain off .

7141 Emergency operation
7142 Emergency operating function type
Emergency operation (7141)
Emergency operation can be activated and deactivated
manually.
• Off
Emergency operation is deactivated.
• On
Emergency operation is activated.
Emergency operating 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.
Simulation
Line Nr Programming line
7150 Simulation outside temp
Simulation outside temp (7150):
To make the starting-up and troubleshooting 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.
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.
