on, the fan activates with a delay of max 1.5 seconds. After the light is switched off,
the fan continues to run for a pre-set period of time at the same speed set during the
installation.
WITH HUMIDISTAT & TIMER
The fan is equipped with a humidity detector, whose threshold is adjustable from 50% to
95% Relative Humidity, and with a timer which is adjustable from aprox. 1 minute to 25
minutes via corresponding trimmer (Fig. 50B).
Turn the trimmer HY completely clockwise and the humidistat function is deactivated.
Automatic humidistat operation: connected according to the diagram in Fig. 49B, when
the percentage of Relative Humidity exceeds the pre-set intervention threshold, the
fan starts up automatically. When the percentage of Relative Humidity goes below the
threshold, the fan continues to function for a pre-set period of time.
Operation via switch connection: connected according to the diagram in Fig. 49B, after
the light is switched on, the fan activates with a delay of aprox. 1.5 seconds. After it is
switched off, the fan continues to function for a pre-set period of time.
Attention: When the relative humidity level is higher than the pre-set threshold,
automatic operation with humidistat has priority over manual operation, or rather the fan
cannot be stopped via switch.
