- To decrease the time delay turn it Counter Clockwise (CCW).
- To increase the time delay turn it Clockwise (CW).
EDM models C, CR, and CH
These models are fitted with automatic shutter.
WARNING: The opening of the shutter is facilited by means of a thermal system that needs
some seconds to open completely.
EDM models H and CH
Models H and CH are provided with an electronic hygrostat which can be adjusted from 60 to
90% RH (% relative humidity). They are fitted with a pullcord switch (IC) enabling override of the
fan when the relative humidity level in the room is lower than the set % RH value.
A variable % RH rotary switch within the fan can be adjusted after removing the grille (Fig. 8).
Alternatively, the EDM-H and CH can be powered by the light switch in preference to the pull
cord switch.
Operation
Case 1: Automatic operation (Fig. 9)
In this mode the pull cord switch is enclosed behind the grille, in the «off» position (The pilot lamp
will not switch on).
The hygrostat causes the extractor to operate automatically when the humidity level in the room
is higher than the level shown on the variable rotary switch. Likewise, the extractor will stop au-
tomatically when the humidity level drops below the selected level.
WARNING: When the extractor is operating by hygrostat, the red pilot lamp on the grille of
the EDM is not on.
Case 2: Auyomatic operation with pull cord override facility (Fig. 10).
Automatic operation as in case 1 with the facility to override the hygrostat by means of the pull
cord when the humidity level in the room is lower than the selected level on the rotary switchl.
Ehen the pull cord is used to power the fan the red pilot lamp (L) turns on.
Case 3: Automatic operation with facility to override by light switch (Fig. 11).
The operation of the extractor is the same as in case 2 although, the EDM is connected to the
light switch (IL) instead of the pull cord.
In this case leave the pullcord inside the fan in the «off» position.
WARNING: When the relative humidity level in the room is higher than the level selected on
the rotary switch, the automatic operation overrides the manual operations (i.e.pull cord
or light switch), that is, the extractor cannot be stopped by either the pull cord or the light
switch.
Maintenance
The extractor needs only a periodical cleaning using a cloth lightly impregnated with a soft de-
tergent.
