Delay On
A delay can be set so that the unit will not respond to an input until after the set delay has elapsed, applies to LS
inputs only.
Overrun Timer
The unit can be set to run for a defined period after the input is removed, applies to LS inputs only.
Humidity – Rapid rise*
Rapid Rise humidity response functions to detect rapid rises in humidity when the ambient %RH is under the threshold
setting. If a rapid rise is detected the fan will boost until the humidity lowers again.
Humidity – Ambient response*
When ambient response is enabled the threshold set point is modified based on the ambient temperature. This helps
to prevent nuisance boosting of the unit as temperatures changes during the day.
Humidity – Threshold*
The unit will boost when the RH is above the threshold set point.
CO
threshold Boost / Purge*
2
The unit will go to Boost / Purge when the detected CO
Analogue inputs
Both analogue inputs have adjustable low and high trigger voltages within the 0-10V range.
The response to being above or below either of the threshold voltages is user settable.
Note: The display doesn't show a decimal point, for example at threshold voltage of 5.2V,
is displayed as "52" on the unit.
Digital Inputs
The unit can be set to change speed (selectable), based on whether the digital inputs are above or below the
threshold voltage. See the table of Low Voltage Connections for details.
Display Lock
To protect the settings on the MEV unit a pin code can be enabled via the main menu.
Once the lock function has been enabled the Pin code can be set.
The 3 digit pin is A to F, 0 to 9, and the default is LoC.
* If external RH or CO
their value will also be displayed on the unit in preference to the internal sensor.
UNIT ADJUSTMENT
1. Commissioning and configuration on all products is supported
by the 3 digit user interface and associated push buttons.
2. When powered on, the unit will display the firmware revision number, after a few seconds the unit
will display the first option in the menu structure (see below).
3. The display will enter standby mode after 30 seconds, press the Mode button to turn the display
back on.
4. Changes to the settings can be made

5. When setting the speeds, there is an internal logic: Low<Normal<Boost<Purge.
I.e., Boost is always higher than Normal.
6. The actions for each of the Live Switched (LS), inputs are selectable. The setting for delays and
over run timers are applicable to all inputs.
7. To restore factory settings, Press and hold "Mode" button for 10 seconds
Wireless units can be commissioned via the Bluetooth connected App.
