INFORMATION
Only for systems with integrated domestic hot water tank: If backup heater
operation during space heating needs to be limited but can be allowed for domestic
hot water operation, then set [4‑00] to 2.
Emergency
To keep energy consumption low, we recommend to set Emergency to auto SH
reduced/DHW off if the house is unattended for longer periods.
# Code
[9.5.1] [4-06]
INFORMATION
The auto emergency setting can be set in the menu structure of the user interface
only.
INFORMATION
If a heat pump failure occurs and Emergency is set to Manual, the room frost
protection function, the underfloor heating screed dryout function, and the water
pipe antifreeze function will remain active even if the user does NOT confirm
emergency operation.
HP forced off
HP forced off mode can be activated to allow the backup heater to provide
domestic hot water and space heating. Cooling is NOT possible when this mode is
activated.
# Code
[9.5.2] [7-06]
Glycol Filled system
This setting gives the installer the possibility to indicate whether the system is filled
with glycol or water. This is important in case glycol is used to protect the water
circuit against freezing. If NOT set correctly, the liquid in the piping can freeze.
