The units can be precisely programmed to determine how they respond to changes in sensor values or the
status of the various signal inputs. The units will run at a Normal flowrate until a sensor or input change
causes it to change speed. In the case of the Switched Live, Digital, Analogue, Wired and Wireless inputs
the units will perform a step change in speed to the appropriate new level. In the case of the Humidity
Sensor and CO2sensor the unit can be programmed to give a response to the change in conditions.

INSTALLATION
Position the unit, taking into consideration the position of the rooms to be ventilated, the exhaust position
and the electrical services. Ensure there is adequate access for installation and maintenance. The unit can
be mounted horizontally or vertically. It can be positioned on the floor, wall or ceiling.
If the unit is sited in the heated void of the dwelling a condensate drain should not be necessary.
When sited in a cold void, consideration should be given to fitment of a condensate drain. Alternatively the
unit and ducting can be externally insulated to minimize condensation within the units housing.
To reduce the system resistance in your duct system, and thereby avoid an increase in speed, power
consumption and sound of the fan, follow these guidelines:
1.1. Keep the length of duct runs to a minimum, particularly the exhaust duct run.
1.2. If you need to use flexible ducting, make sure that it is fully extended and not crushed,
sagging or torn.
1.3. Tryto minimize the systems pressure dropby designing for lower in-duct velocitiesand connect to
the rooms with low pressure drop ceiling valves.
1.4. The bend radius (measured to the inside of the bend), should be at least 1x the duct diameter.
1.5. Avoid having any bends, filters or other obstructions within 250mm of the fan inlets and outlet.
1.6. Set the valves to their maximally opened positions for a minimal pressure drop.
Securely mount the unit through the mounting holes on the casing using appropriate fixings for the
mounting substrate. Anti-vibration mounts; acoustic mat or rubber bushes can also be used.
Fixings (not supplied) must be capable of securing 4 x the weight of the unit. Unit weight: 4.1kg
To maintain the Ingress Protection (IPx2) rating of the unit, the unit must NOT be mounted with the
cover removal slots facing upwards, or at an angle where they are visible from above.
All other orientations are acceptable. Do not mount the unit with the outlet duct pointing down.
See the dimensional details below for the mounting hole positions.
Spigots are 125mm diameter. 125 –150mm accessory adaptors are available.
When installing Ø90mm ducting onto a Uniflexplus+ unit, keep inserting the
ducting into the sockets until three clicks have been heard.
Full insertion of the ducting is necessary to achieve a
seal with the unit.

WIRING
WARNING:
THE UNIT AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED
FROM THE POWER SUPPLY DURING THE INSTALLATION / OR
MAINTENANCE. THIS UNIT MUST BE EARTHED.
1. To remove the cover, use a coin or similar; depress the retaining tabs via the slots in the side of the
unit.
2. With the power off, connect a suitable mains power cable from a switched, fused spur to the screw
terminal block. Use the cable clamps and clip provided to secure the lead.
3. Two mains voltage Live Switched (LS1 and LS2) connections are provided, and can be used to
trigger a change in speed. Common inputs would be from a bathroom lighting circuit. When
commissioning the unit, a delay on timer and an overrun timer can be selected and adjusted in the
software using the buttons and screen. See Unit Adjustment section on page 12 of this document
for details.
4. The switched live output (230Vac) from any other switch or controller, (such as a simple latching pull
cord or push button switch, humidistat or PIR detector) can be connected to the LS terminal instead
of connecting to a lighting circuit.
5. Important: Use low voltage twisted pair, data cable for accessories that are connected via the IO
(Input Output) PCB. See the Low Voltage Connections diagram, use the cable clamp and grommet
provided.
6. There are no, delay-on or overrun timers when connecting via the Low Voltage connections (B), as
the controller should determine when the fan is running at Boost or Normal speeds. Use the LS
connection described above if a timer is needed.

RF868 Wireless inputs
Units that contain a Wireless receiver can be paired with compatible sensors, these can be mains or battery
powered depending on the sensor.
A maximum of 15 wired and wireless sensors can be connected to a single unit.
Pairing sensors
To pair the unit with a wired or wireless sensor:
- Press the Mode button to turn on the display.
- Press and hold the Mode button until the LED illuminates solid White
- Release the mode button, the LED will flash White to indicate that it is in pairing mode.
The unit will remain in pairing mode for approximately 1 hour, or until the mode button is pressed
again. Multiple sensors can be paired while in pairing mode.
- Activate the pairing function on the sensor to be paired (see the instructions that came with the
sensor).
- When a sensor is paired the total number of paired devices is displayed on the unit.
Removing sensors
To remove paired sensors, the unit must be reset. Caution, this will reset all values back to factory default.
- Press the Mode button to turn on the display.
- Press and hold the Mode button until the LED illuminates solid Red
- Release the mode button, the LED will stay Red.
- Pressing the Mode button again will confirm the reset command. If a reset is not wanted, leave the
unit until the command times out and the LED turns off.
C: Sensor priorities
The unit set the motor speed based on the source in the following order:
User override
LS inputs (1 and 2)
Digital inputs (1 and 2)
Sensor override: The Sensor override action is decided based upon the Sensor input (Humidity Sensor, Co2
sensor, Analog inputs ) whichever sets the motor to run in Highest speed.
Default speed (run in normal speed)
Note: At each priority state, if more than one inputs are active (e.g. Digital input 1 and 2 are active), then
motor will always run at a speed from the input which has highest speed level.
Figure 15

12
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.
CO2threshold Boost / Purge*
The unit will go to Boost / Purge when the detected CO2level 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 CO2sensors 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.

13
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
via the +and –buttons, the Mode button will
