Ensure that this is not directly exposed to a heat source or stream of
light in order to obtain the most precise measurement of the ambient air
possible. A small voltage in the sensor cable is thus harmless for the
surroundings.
Now insert the power plug into the socket. The fan controller initialises
itself, this can last up to 10 seconds and the green On light flashes and the
fans run at 50 % of their power. Following initialisation ON lights up
continuously – the fan controller regulates from this point onwards.
Explanation of the functions which may be available depending on the
model:
The desired temperature is set with the button "Temperature setting".
The regulator starts regulating from the set value and at 2 degrees of
excess temperature it is at 100% of its regulation power. (Exception
regulator with hysteresis setting)
The desired humidity is set with the button "Humidity setting". The
regulator starts regulation from the set value and at 10 rh of excess
humidity it is at 100% of its regulation power.
The minimum speed of the exhaust fan which must never gone below
is set with the "Minimum speed setting" button. This function can also be
switched off with the "off" setting. The fan is automatically switched on via
temperature or humidity if required.
By default the intake air fan always switch OFF when the values are
below them setting. A Jumper JMP2 in the inside of the controller can
change his behaviour. Close the Jumper JMP2 if you want the Intake air fan
to keep the same minimum speed setting as the exhaust air fan. (See
picture)
The maximum speed setting which must never be exceeded in order to
prevent loud noises at full capacity is set with the "Maximum speed setting"
button. The maximum speed setting is subject to the function of the
minimum speed setting.
