For good EMC engineering practice, any sensor cables
or switched live cables should not be
placed within 50mm of other cables or on the same
metal cable tray as other cables.
The unit is normally designed to ventilate the property
continuously to give between 0.5 and 0.7 air changes
per hour.
A facility is included which boosts the duty as required.
The boost can be achieved by the following methods:
a) Switched Live (SL)
Connection of 230V mains to SL terminal.
b) Optional Remote Speed Control (OPUS-SPD)
The speed control will mimic the speed between the max
and min settings selected at the fan. Connect OPUS-SPD
to LV terminal.
c) Internal Humidistat (on the ES-MEV-H unit only)
The internal humidistat can be found on the base of the
fan case. The adjustment dial gives a range of 50 - 80%
@ 20
0
C. (See figure 8). Setting to mid position gives 65%
which should be acceptable for most circumstances.
