4.22.4.2. fail-Safe mode setup
The fail-safe mode defines the system status if the RF communication is lost (e.g. when the
room Unit
stops
communicating due to discharged batteries). If the system is a direct (radiator one), then the factory setting will make the
system revert to a set point of 10°C for frost protection. If indirect loops are added, the system will continue to operate at the
last communicated setpoint.
