RANGE
MF100 / MF100 LV / MF 250 :
standard model, normally operated by means of a control switch.
MF 100C / MF 250C :
incorporate a pull-cord for turning the fan on and off.
MF100T / MF 100 T-LV / MF 250T:
with adjustable Overrun Timer. Can either be wired via a light switch or via a remote (illuminated) switch. When
the light is switched on , the fan will operate , and when the light is switched off, the fan will continue to run for the pre-set length of time.
MF100HCT / MF 100 HCT-LV / MF 250 HCT:
with Humidistat , Cord and Overrun Timer. This fan has an integral, adjustable, electronic humidistat,
which is sensitive to the level of moisture (relative humidity) in the air. The fan starts and continues to operate until the humidity has fallen beneath the
pre-set level and the timer has completed the over-run period. The pull-cord override allows the fan to be operated manually regardless of the humidity
level (a neon light indicates that the fan is operating in this mode). Pulling the cord again will make the fan revert to being operated automatically by
the humidistat and/or the over-run Timer. The fan can also be operated by a remote (light) switch.
MF100H2C / MF 250 H2C:
with Humidistat , 2 speed, Cord and Overrun Timer. 2 speed models with integral, adjustable, electronic humidistat, which
is sensitive to the level of moisture (relative humidity) in the air. The fan starts and continues to operate at low speed until the humidity has fallen
beneath the pre-set level and the timer has completed the over-run period. Pulling the pull-cord override will boost the fan to its maximum speed. The
neon indicator will come on showing that the fan is being operated manually. Pulling the cord again will make the fan revert to its low speed and to
being operated automatically by the humidistat and/or the over-run Timer (the neon indicator will switch off).
MF 250 H2R:
2 speed model, with Humidistat, Remote Switch and Overrun Timer. Same as H2C, but using a remote dedicated 2 poles switch instead
of the pull cord, to boost the fan to maximum speed.
MF 100 2C / MF 250 2C:
2 speed models with Cord. These fans operate permanently at the lower speed and can be boosted to a maximum speed by
means of the pull-cord. Pulling the cord again reverts the fan to its lower speed. Can be wired also with a dedicated switch or a light switch
(OPTIONAL), giving OFF and 2 speed.
MF 100 2C LV / MF 100 2R LV:
2 speed, Low Voltage models. These fans operate permanently at the lower speed and can be boosted to a
maximum speed by means of the pull-cord (2C) or remote dedicated switch (2R). Pulling the cord again reverts the fan to its lower speed.
N.B.
Both the humidistat and timer on all fans may be adjusted by following the instructions on the front of the printed circuit board (Fig 4).
Always disconnect the fan from the power supply before carrying out any operation.
The humidistat is pre-set at the factory to operate the fan when the humidity level reaches 70%.
All versions with Humidistat incorporate a controlled temperature set-back allowing the humidistat to take into account variations in the ambient
temperature and to avoid the fan switching on unnecessarily. This reduces fan operation at night.
