• Emergency mode
If the heat pump is not operating properly, an emergency operation can be maintained. The emer-
gency operation enables the installation to be run with the available heaters (flow, DHW tank). In
this case, the compressor will remain off.
– Emergency operation: Emergency operation can be activated and deactivated manually.
• Off
Emergency operation is deactivated.
• On
Emergency operation is activated.
– Emergency operation function type:
• Manually
Emergency operation can be activated/deactivated only though the emergency operation set-
ting 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 operation
may however be activated/deactivated manually via the emergency operation setting on line
7141.
• Simulation
– Simulation outside temperature: To make the starting-up and troubleshooting processes easi-
er, it is possible to simulate an outdoor temperature in the range of -50...+50 °C. During simula-
tion, the current, composite, and attenuated outdoor temperatures are ignored and substituted
with the adjusted simulation temperature. Computation of the 3 outdoor temperatures based on
the actual outdoor temperature continues to be performed during the simulation, and these tem-
peratures are available again when the simulation is over.
This function can be deactivated by selecting -.- on this line or automatically, after a 5 hours
waiting period.
