When the user interface used as room thermostat is disconnected (because of
incorrect wiring or damage of the cable), then room frost protection is NOT
guaranteed.
NOTICE
If Emergency is set to Manual ([9.5]=0), and the unit is triggered to start emergency
operation, the unit will stop and need to be recovered manually via the user
interface. To recover operation manually, go to the Malfunctioning main menu
screen, where the user interface will then ask you to confirm emergency operation
before starting.
Room frost protection is active even if the user does NOT confirm emergency
operation.
Setpoint range
Only applicable in room thermostat control.
To save energy by preventing overheating or undercooling the room, you can limit
the range of the room temperature for heating and/or cooling.
NOTICE
When adjusting the room temperature ranges, all desired room temperatures are
also adjusted to guarantee they are between the limits.
