Choosing a building drying program automatically binds inputs and external sensors according to
the table below to reduce the amount of necessary manual setup. These settings can of course be
changed, if so desired.
Programs – Building drying
Program 688 – Only room drying
A room‘s humidity is to be reduced. As soon as the absolute humidity outdoors falls below the hu -
midity indoors , a fan is activated.
The fan runs, if
• the absolute humidity outdoors falls below the absolute humidity indoors
and
• the optional interval operation („timer“) is active and
• the relative humidity indoors exceeds the minimal humidity min1 .
A1 = S5 > min1 & S1 > (S2 + diff1)
No time programs can be set up for this program.
Program 689 – Room drying and minimum temperature monitoring
A room‘s humidity is to be reduced. If it becomes too cold in the ventilated room, the fan is deacti -
vated.
The fans runs, if
• the absolute humidity outdoors falls below the absolute humidity indoors
and
• the room temperature is high enough (to prevent excessive cooling in cold seasons) and
• the optional interval operation („timer“) is active and
• the relative humidity indoors exceeds the minimum humidity min1
A1 = S5 > min1 & S1 > (S2 + diff1) & S3 > min3
No time programs can be set up for this program.
