FEATURE DESCRIPTIONS
If compatible, the unit can be controlled via the Bluetooth linked App. This is only available on Multihome
Wireless units.
Comfort mode
If Comfort mode is enabled the unit will behave as follows to all LS inputs:
Trigger
Action
LS input active less than 5 minutes
No action (continue to run at Normal speed)
LS input active more than 5 minutes but less
than 20 minutes
Once LS input is removed, fan will run at user
selected speed for the length of time LS was
present plus the set over-run time (if over run is
enabled).
LS input active more the 20 minutes
Unit will Boost after 20mins.
Once LS input is removed, fan will run at user
selected speed for 20 minutes plus the set over-
run time (if over run is enabled).
The above applies to all LS inputs. The times are not adjustable by the user.
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 an 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
2
threshold Boost / Purge*
The unit will go to Boost / Purge when the detected CO
2
level exceeds the set thresholds.
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
2
sensors are fitted via RS485, they will have priority over the internal sensors,
their value will also be displayed on the unit in preference to the internal sensor.
