Т — timer
Manual actuation of external switch S1 enables the fan and switches on the lights with a 50 second activation delay. Once
external switch S1 is returned to the initial position the fan shuts down after a 6 minute timer delay.
ТР — user-adjustable timer
Manual actuation of external switch S1 starts the fan at Speed 2 and switches on the lights simultaneously. The delay
time is set within the 0-150 second range by means of the internal controller. The timer run-down time after S1 switch
disengagement is set within the 2-30 minute range by means of the internal controller.
I — intermittent operation mode switch
While running at Speed 1 the fan intermittently switches to Speed 2. The interval between Speed 2 cycles is set by means
of the internal controller within the range from 30 minutes to 15 hours. Each cycle lasts for 10 minutes. Can be activated
manually with external switch S1 simultaneously with the lights (with a 50-second activation delay). When switch S1 is set to
OFF, the fan reverts to the original state.
H — humidity sensor
The fan switches to Speed 2 when the relative humidity in the room reaches a certain level. The humidity threshold can
be adjusted in the 60 % to 90 % range. The fan shuts down when the relative humidity level drops 10 % below the pre-
set threshold. Manual actuation of external switch S1 switches the fan to Speed 2 simultaneously with the lights with a
50-second activation delay whereas the run-down time after switch S1 disengagement is set within the 2-30 minute range
by means of the internal controller.
