WITH HUMIDISTAT/TIMER
The fan is equipped with a humidity sensor, whose threshold is adjustable from 50% to
95% Relative Humidity via dedicated trimmer, and with a timer which is adjustable from
0 to approx. 30 minutes via dedicated trimmer (fig. 15).
The fan runs continuously at selected trickle speed (set by the jumper switch combination
- see figure 16), increases its speed in case the percentage of Relative Humidity exceeds
the settable threshold, and can anyway be boosted with a dedicated ON/OFF switch (or
PIR, CO2… sensor) or with a light switch (fig. 14). Trickle speed can be set to off.
To deactivate the humidistat function, turn the trimmer HY completely clockwise.
Automatic humidistat operation: when the percentage of Relative Humidity exceeds the
settable threshold, fan speed automatically increases to “comfort boost” speed, which
is intermediate between the selected trickle speed and the boost speed. When the
percentage of Relative Humidity goes below the threshold, the fan continues to function
at “comfort boost” speed for a factory set period of time then returns to selected trickle
speed.
Operation with external switch: connected according to the diagram in figure 14. When
the external switch is turned on, the fan is boosted. After the external switch is turned
off, the fan continues to run at boost speed for a settable period of time, then it returns
to selected trickle speed (or to “comfort boost” speed in case automatic humidistat
operation is on). The front cover LED indicates when the external switch is on.
The over-run timer function is activated only if the external switch has been on for at
least 60 seconds.
