- In order to ensure correct measurement of humidity levels, the fan must be
installed in an area where there is good air circulation.
- Ensure that the fan is inside the room that it is to be installed in when setting
the humidity level.
- If the humidity level is consistently above 90%, the fan will continue to run
without stopping.
Operation
Case 1: Automatic operation (Fig.8).
The humidistat causes the extractor to operate automatically when the humidity
level in the room is higher than the set level. The extractor will stop automatically
when the humidity drops below the selected level and after the selected period,
set on the timer.
Case 2: Automatic with manual override.
Automatic operation as in case 1, but with the facility to override the humidistat
by means of the light switch (Fig.6), when the humidity level in the room is lower
than the selected level. In this case, the extractor continues to operate for the
period set on the timer, after the light switch has been switched off.
ATTENTION: When the humidity rises above the selected value, the
automatic option takes precedence over the manual and the unit cannot
then be switched off using a switch.
Settings:
The fans are set to operate at 60% relative humidity and with 2 minutes run-on
time. If the humidity in the room is lower than 60%, the fan will not turn on. If it is
higher, the fan will operate until the humidity level drops below 60%RH and then
runs for the length of time set by the timer. The desired humidity level and time
delay are set by means of adjusters positioned on the printed circuit board (fig. 9)
and accessible once the grille (1) has been removed.
The humidity is set by the adjuster. “
% Hr
”
- To increase the humidity setting turn anticlockwise (min.60 %)
- To reduce the humidity setting turn clockwise (max. 90 %)
The timer is set by the adjuster “
t min.
”
- To reduce the run-on time, turn anticlockwise (min. 2 minutes)
- To increase the run -on time, turn clockwise (max: 20 minutes).
ATTENTION: When the fan is operating on run-on time phase, it must finish
before adjusting to a new setting.
