BEFORE ADJUSTING THE CONTROLLER, SWITCH OFF THE MAINS SUPPLY. HUMIDISTAT SHOULD ONLY
BE ADJUSTED BEFORE OR DURING INSTALLATION.
1. Remove the fan grille. The controller is factory set to switch on at about 70% RH. The
humidity set point can be adjusted from 50-95%RH by altering the adjuster on the control
PCB.
2. To LOWER the set-point use a small screwdriver to turn the adjuster
(Fig.6.) ANTI-CLOCKWISE. This makes the controller MORE sensitive.
3. To RAISE the set-point use a small screwdriver to turn the adjuster
(Fig.6.) CLOCKWISE. This makes the controller LESS sensitive.
4. Replace the fan grille.

SERVICING AND MAINTENANCE.

MUST BE ISOLATED FROM THE POWER SUPPLY DURING MAINTENANCE.
1. At intervals appropriate to the installation, the fan should be inspected and cleaned to
ensure there is no build-up of dirt or other deposits.
2. Carefully push the front panel of the grille upwards away from the base part of the grille
(Fig. 5).
3. Wipe the inlets and front face with a damp cloth until clean.
The fan has sealed for life bearings, which do not require lubrication.

DATA LOGGER

The fan records the number of days it has been running for. In order to use this feature, power to
the fan needs to be switched off and the flat outer grille removed by pushing it upwards. When
the fan is switched back on again, after 30 seconds, a blue LED on the electronics control board
will light up (See Fig.7 for location). The LED will turn off after 5 seconds; it may then flash a
number of times before it comes back on again. Count the number of flashes, if there are no
flashes then the number is 0. The number of flashes represents number of thousands of days.
This process is repeated 3 more times with the second set being 100s of days, third 10s of days
and finally single days. The number of days recorded cannot be reset and will continue to count
from the displayed number.
For example, the fan is turned on then after 30 seconds; the first set of flashes counts 1, second
set 6, third set there are no flashes and the final set has 9 flashes. This means the fan has run for
a total of 1609 days.
The LED will also illuminate when the
fan is boosting via LS input.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT
The LED will be visible
through the cover here.
