Fig. 06-12 Web page: Set up daily program, new time span
After confirmation the time span in the morning is
enlarged.
Note:
When "Auto start" function is enabled in room configura-
tion, the system tries to reach the set points for normal
mode in time at the begin of the defined time period.
The time span determined for the autostart function is
continuously updated.
During this period, fan coils continue to work with the
value specified in the time program in order to give
priority to the other systems.

06.07 Dehumidifier settings
Dehumidifiers are required depending on climatic
conditions. The dehumidifiers are assigned to indi-
vidual rooms and are controlled via timer programmes.
The limit values for switch-on (relative humidity,
calculated dew point) and the assignment to timer
programms can be defined in the menu "Dehumidifier
settings".

The weekly program switches between normal and
reduced operation, same as it is with the setpoints for
the room temperature. The reduced operation, usually
during the night, reduces the impairment caused by
the inevitable operating noise of the devices.
The values for reduced operation have therefore been
intentionally chosen in such a way that in this phase
the dehumidifiers are only started when it cannot be
avoided.
Default values of relative humidity:
▪ normal operation: 55 % r.H.
▪ reduced operation: 80 % r.H.
The relative humidity indicates the extent to which
the air is saturated with moisture. Too high humidity
is perceived as unpleasant, and it can even lead to
condensation on cool surfaces. Too low humidity can
lead to skin irritation and breathing problems.
