OVER-RUN TIMER
This product controls automatically the
over-run time, which is proportional to the
time that has been needed to bring the
relative humidity level to the adjusted level,
depending on which the over-run will range
from 2 minutes to a maximum of 20
minutes.
Operation
Case 1: Automatic operation (fig.9)
In automatic operation, the humidistat causes
the extractor to operate automatically when
the humidity level in the room is higher than
the pre-set level. The extractor will stop
automatically when the humidity drops below
the selected level and after the selected
period set on the over-run timer.
Case 2: Automatic operation as in case (1)
but with the facility to override the humidistat
by means of the light switch (fig.8), when the
humidity level in the room is lower than the
selected level. In this case, the extractor
continues to operate for the selected period of
time (over-run timer) after the switch light has
been switched off.
- If the period of operation is less than 50
seconds then the over-run timer will not
operate.
- If the period of operation is more than 50
seconds then the over-run timer will operate
in accordance to the pre-set time period.
ATTENTION: When the humidity rate is
above the selected value, the automatic
option takes precedence over the manual
and the unit cannot then be switched off
using a switch.
SILENT-100 CDZ (this version is only
available as SILENT-100)
Models provided with a PIR (passive infra-
red) detector. The unit starts automatically

on" timer (1 to 30 minutes), and the unit will
continue to operate for the set period after
initiation by the movement detector.

potentiometer on the printed board (fig.7):
- T o reduce the "run on" time,
anticlockwise (min. 1 minute)
- T o increase the "run on" time, turn clockwise
(max: 30 minutes).

cleaning using a cloth lightly impregnated
with a soft detergent.
