EMERGENCY MODE
Emergency mode is used in event of operational interference
and in conjunction with service.
When S735 is put into emergency mode, the system works
as follows:
• The compressor is blocked.
• S735 prioritises heating production.
• Hot water is produced if possible.
• The immersion heater is stepped according to the setting
in menu 7.1.8.2 - "Emergency mode".
• Fixed supply temperature if the system has no value from
the outdoor temperature sensor (BT1).
You can activate the emergency mode both when S735 is
running and when it is switched off.
When the emergency mode is active, the status lamp is yel-
low.
To activate when S735 is running: press and hold the on/off
button (SF1) for 2 seconds and select "emergency mode"
from the shutdown menu.
To activate emergency mode when S735 is switched off:
press and hold the on/off button (SF1) for 5 seconds. (De-
activate the emergency mode by pressing once.)
