The WCH fan is designed for the automatic control of the
fan as well as controlling the extended operation mode.
Two types of activation systems are used — with a
humidistat or with a control signal. The extended
operation mode can be adjusted as needed. The
extended operating mode is the period of time that starts
when
— the light is turned off in the room (activated by the
control signal — cable connection to the "T" terminal
according to the diagram) and continues for the time set
on the potentiometer "CZAS" (TIME)
— the level of relative humidity decreases below the
value set on the potentiometer "WILG" (HUMIDITY)
(the fan will drain the given humidity level of the room)
and continues for the time set on the potentiometer
"CZAS” (TIME)
Setting the operation parameters for the humidistat
Using an insulated Philips screwdriver, slowly turn the
potentiometer "WILG" (HUMIDITY)
from the extreme
right position to the left until the fan turns on. Then the
potentiometer should be slightly turned back to the right.
The fan should turn off after the time is set on
potentiometer "CZAS" (TIME).
In case the fan does not
turn off, the “WILG”
potentiometer should be turned
slightly more to the right. You can check the settings of
the operation parameters by blowing on the humidistat
sensor from a distance of 15 cm, which will activate the
fan. The sensor examines the level of the relative humidity
in the place where it is installed.
Caution! The above actions should be performed by
an electrician with proper qualifications.
Depending on your needs, extended operation mode can
be conveniently adjusted via the potentiometer "CZAS"
(TIME) by using a Philips insulated screwdriver to slightly
turn from the left to the right side, increasing the time of
operation. And from right to left to decrease the time. To
activate the fan using the humidistat option, there is no
need to connect the control signal at the "T" terminal.
Controller adjustment installation and maintenance
should be carried out by an electrician with the proper
qualifications. If the controller is damaged due to
improper installation, the complaint will not be taken into
account!
The control signal is given by the lighting switch to the "T"
terminal, the signal must have the same polarity as the "L"
terminal – electricity phase.
Standard settings — HUMIDITY-max., TIMER-min.
