TYPICAL EXTRACTION LOCATIONS – BATHROOMS, TOILETS, LAUNDRIES, KITCHENS
The unit uses a highly efficient backward curved centrifugal motor impeller
set and is designed for continuous 24 hour use. Four settable speeds can be
configured to change these speeds based on an integrated sensor or separate
switch inputs (not supplied). The unit will run at a normal flow rate until
the humidity sensor or external switch input trigger a speed change. In the
case of the switched live and digital inputs, the units will perform a step
change in speed to the appropriate level. In the case of the analog inputs and
humidity sensor, the unit can be programme to give a proportional response to
the change in conditions.
The extracted air is replaced through natural air flow through the gaps around
doors and windows, trickle inlet slots, or best of all, the Manrose Puro
Filtered Passive Vent Kit (DCT4565) with typhoon cowl that has an effective
aerodynamic area of 3000mm2 without the filter and 1400mm2 with the filter
fitted.

MultiVent Continuous Extract Ventilation
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.
If the unit is sited in the heated void of the dwelling a condensate drain
should not be necessary. When sited in a roof cavity, 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 therefore lower the
speed, power consumption and noise of the fan, follow these guidelines: · Keep
the length of duct runs to a minimum, particularly the exhaust duct run. ·
When using the flexible ducting in the kit, make sure that it is fully
extended and not crushed, sagging or torn. · Try to minimize the use of
diffusers/valves by having similar length duct runs to the inlets. · The bend
radius (measured to the inside of the bend), should be at least 1x the duct
diameter. · Avoid having any bends, filters or other obstructions within 250mm
of the fan inlets and outlet.

location central to all of the rooms that you are planning to extract from.
Also remember that the unit could create noise and should be mounted away from
bedrooms. Mount the MultiVent using the 4 mounting points. Bear in mind that
the exhaust (main extraction) is using 150mm aluminium foil ducting and a
150mm weather proof cowl. Each kit contains 3 x 6m lengths of 125mm aluminium
foil ducting for the extraction points.
· Cut a 126mm (minimum) hole in the required locations in the kitchen (minimum
2m away from the stove top), bathroom and toilet. · Disassemble the 125mm
diffusers (DCT0186) and mount the 125mm spigots to the ceiling in each
location using the four screws supplied. · Fit the diffuser escutcheon by
pushing it into the spigot.
· Extend the 125mm aluminium foil ducting and slide the spigot collar over the
ducting by approximately 150mm. · Slide the 125mm aluminium foil ducting over
the spigot. · Slide the spigot collar over the ducting pressing it firmly all
the way down the spigot clamping the aluminium foil ducting in place on the
spigot.

FEATURE DESCRIPTIONS
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 overrun 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 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.
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 MultiVent 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.

COMMISSIONING TYPICAL 3 ROOM SYSTEM
In the following step we will provide an example of how to wire and control an
MultiVent system hardwired to a Bathroom, Kitchen and Toilet. The MultiVent
will utilize Humidity Rapid Rise in its response and the 2 larger rooms
(Bathroom and Kitchen) will also provide a PURGE speed function if these 2
rooms are switched on together. Before commencing please ensure that all power
is OFF and ensure that it is electrically safe before starting. Wire the
230VAC connections as per the diagram below. Wire mains connections from a
suitable source (lighting circuit) or add a new dedicated circuit from an RCD
protected 10A MCB with the cable to L (live – BROWN), N (neutral – BLUE) and E
(protective earth GREEN/YELLOW). Wire a 230V connection from a switch
located in the Bathroom that could be either a dedicated FAN switch (or a
connection from a LIGHT switch) and connect the L (BROWN) wire back to LS1. Do
the same from a switch located in the Kitchen and connect the L (BROWN) wire
back to LS2. Hardwire a NEUTRAL LINK (BLUE or BLACK) from the N (neutral –
