Window airing function
As soon as the central apartment unit detects an open window, the window
airing function is activated in the corresponding room. In that case, the radia-
tor control valve is limited to its current travel, even if the room temperature
drops.
If the window remains open after the set window airing hold time, the room
operating mode is lowered to Protection mode.
The window airing function is aborted as soon as all window contacts in the
respective room have closed again
F Window (0 = all closed, 1 = min one open)
R Room control
RB Control mode
V Hold valve position
SB Protection
t Time
The desired window airing hold time (00.00..06.00 hh.mm) can be defined for
each room.
Main menu > Rooms > Room X > Room settings > Window airing:
Factory setting 00.30 hh.mm.
Setting “00.00“ deactivates the window airing function. The window
contacts do not influence room control.
Silent mode
The SSA955 radiator control actuator can also be operated in silent mode
when used in noise-sensitive rooms (e.g. in the sleeping room).
Silent mode increases the actuator’s power consumption, thus reduc-
ing battery life.
Main menu > Rooms > Room X > Room settings > Silent mode:
Off Silent mode is off (factory setting).
On Silent mode is on.
