MEV-ECO(-H)
Installation Manual
5.0 COMMISSIONING
Due to potential access to live parts adjustment of set points must
only be carried out by a suitably qualified person, adjustment
should only be carried out using an VDE approved insulated
terminal screwdriver.
The clear panel covering the ventilation controls has an adhesive
backing which should be exposed and sealed post commissioning to
prevent tampering and ensure the IPX4 rating is met.
All commissioning set points can be accessed through the access holes
of the control cover (Figure 1).
For required airflow rates please refer to the design specification for the
property or building regulations approved document F.
Correct commissioning is essential to ensure the ventilation rates
are met. It also ensures the unit is not over ventilating and causing
excessive power consumption.
Adjustment valves should be locked in place to prevent further
adjustment.
Once commissioned the home owner/tenant should be informed that
the unit should not be adjusted as it will have a detrimental effect
on the indoor air quality and could result in condensation and mould
growth.
5.1 Humidity Adjustment (MEV-ECO-H Only)
The MEV-ECO-H contains an internal humidity sensor, when the unit
senses that the humidity exceeds the set point the unit will boost to
that set by the commissioned boost speed. The set point can be found
on the control cover of the unit (Figure 1) and is at its least sensitive
when turned fully clockwise, the mid-point is approximately 75% RH.
The sensor is measuring humidity from all the wet rooms at the same
time and should not be relied on to solely boost the unit. An additional
switch should be used local to the wet rooms ("Wiring diagrams" on
page 4).
