U Emergency operation
Off: Heat pump functions normally (with boosters if necessary)

On: Heat pump uses the electric boost system or the boiler connection
Use the "On" position only in assist mode or test mode: may result in high power bills
S Emergency operating function type
Manual: Emergency mode is not active when a fault occurs (Emergency mode = OFF)

• Maintenance
Maintenance functions can be used as a preventive step for periodically monitoring the installation.
All maintenance functions can be individually activated or deactivated. The controller automatically
generates maintenance messages if the settings defined are either exceeded or fail to be reached.
– HP interval: Defines the maintenance frequency (in months) for the heat pump.
– HP time since maintenance: Displays the time (in months) elapsed since the last mainte-
nance. If the value exceeds the "Heat pump interval" (line 7070), the symbol
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 op-
eration, obtained over a period of 6 weeks. If the value exceeds the "Compressor 1 maximum
startups/hr op" adjusted setting, the symbol
appear in the Info section:
8: Too many compressor 1 startups (Priority 9)
This setting can be reset with the associated rights of access.
