Standard switching:
Permanent base load operation
Switching on
The unit is running in base load operation, humid-
ity control is active. If the switch-on point is ex-
ceeded, the unit switches automatically over to
full load mode.
Switching off
The unit switches automatically back to base load
operation if the relative humidity falls below the
switch-off point.
H switching variant 1
Permanent base load operation with pre-defined
overrun time
Switching on
The unit is running in base load operation. Humid-
ity control is active, see standard switching.
Switch S1 can manually be switched to full load
operation.
Switching off
After switching full load operation off with S1, the
unit continues in full load operation for an overrun
time of 6 minutes. If, after this time, the humidity
as measured at the unit:
• is higher than the saved reference value, the
fan continues to run in full load operation until
the humidity drops below the reference value.
After the 15 minutes of overrun time, the fan
switches back to base load operation.
• is lower than the saved reference value, the fan
automatically switches back to base load opera-
tion after an overrun time of 15 minutes.
H switching variant 2
Manual base load operation
Switching on
The unit is switched manually to base load with
switch S1. Humidity control is active, see Stand-
ard switching.
Switching off
