Under leaving water temperature control, room frost protection is
NOT guaranteed. However, if room antifrost [1.4] is activated, limited
frost protection by the unit is possible:
External room thermostat control ([C‑07]=1)
Under external room thermostat control, room frost protection is
guaranteed by the external room thermostat, provided that Space
heating/cooling [C.2] is turned ON and the emergency setting [9.5] is
set to automatic.
Room thermostat control ([C‑07]=2)
During room thermostat control, room frost protection is guaranteed
if it is enabled. When room frost protection [2‑06] is activated and the
room temperature drops below the room antifrost temperature [2‑05],
the unit will supply leaving water to the heat emitters to heat up the
room again.

INFORMATION
When the user interface used as room thermostat is
disconnected (due to miswiring, 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.

preventing overheating or undercooling the room, you can limit the
range of the room temperature, both 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.
