Product Overview
This manual is for the range of Titon Ultimate® dMEV Decentralised Extract
ventilation units. All units are designed for continuous extract ventilation of a
single room, for example bathroom, kitchen, toilet or utility area. The units use
an efcient DC motor and bespoke impeller/guide vane combination to produce
high ow rates & pressure.
The unit's controller self-commissions the unit to required set points in both
wall and ceiling mounted systems and reacts to increased external pressure
maintaining air ow rate.
The range consists of:

Product Features
Continuous Speed
The normal running speed of the unit.
Boost Speed
Boost Speed is an increased speed providing higher extract air ow.
High Boost Speed
Maximum running speed to rapidly remove humidity & VOC’s in the dwelling.
Boost Switching
The Boost Speed can be enabled via a switch live input wired into the lighting
circuit or independent switch. A second OFF/ON cycle of this switch live input
within 5 seconds switches the fan to High Boost.
Boost/High Boost Overrun Timer
The timer delays the time in which the Boost/High Boost Speed is engaged when
the switch live signal has been enabled for a specic time variable between 0
and 60 minutes.
Constant Flow
The units are tted with an integrated Flow Sensor. This continuously monitors
the air ow through the unit. If the sensor detects a reduction in air ow then the
fan speed increases to maintain required ow rate.
Data Logging
TP 640HD only: The unit records the length of time it has been in powered use
and the average humidity on a Daily/Monthly/Annual basis. The results can be
recalled via the unit's digital display.
Calibration
The unit is tested and tuned by UKAS calibrated equipment during manufacture.
The details of the equipment and certication can be found on the inside of the
fan.

Wiring
The supply connection to the unit is via a PCB mains terminal block. This is
accessed by loosening the retaining screws (x4) and removing the Top of the
unit. When connections have been made then the unit cable clamp must be used
to rmly hold the cable in position.
When supplied from a 6 amp lighting
circuit no local fuse is required. If
electricity is not supplied via the
lighting circuit, a localised 3 amp fuse
must be used.
The terminal marked with the earth
symbol is for parking only and non-
functional. As the fan is a class II
appliance no connection to earth is
required.

Commissioning
Fascia must be tted prior to commissioning or operating fan.
Control Panel
The unit commissioning and operation is made via the control panel. The panel
consists of 4 buttons; Settings, Fan Speed and Plus/Minus adjustment buttons.
The panel also has a 4 digit display which is visible when buttons are activated
or to show an error present with the unit.
Fan Speeds
The unit Continuous, Boost and High Boost set values can be adjusted via the
control panel. The unit also has a function to ne tune these ow rates when
commissioning with
the use of a cone
anemometer. When a
chosen set ow rate is
made then the fan speed
can incrementally be
increased or decreased
to achieve the exact ow
rate required.

Manual Speed Control
When unit is in operation the fan speed can be manually changed. With either a
remote Live Switch or the buttons on the fan.
Operation of the Live
Switch will activate
Boost. A second OFF/
ON cycle of the switch
within 5 seconds
switches the fan to High
Boost.
Alternatively the buttons
on the fan can be
pressed as illustrated.
When the unit is
manually put into
Boost or High Boost
the unit will run for 60
minutes then return
to Continuous. If an
independent Boost
switch is being used and
is on, then High Boost will return to Boost after the 60 minutes.

Maintenance
WARNING: The unit uses a 230V~ supply and contains rotation mechanical parts.
ISOLATE the unit from mains power supply and allow sufcient time for all moving
parts to stop before undergoing any Servicing or Maintenance.
Cleaning Exterior
For best results remove fascia and clean with a damp cloth with a warm mild
detergent solution. Do not use solvents or abrasive cleaners.
Clean the top of the unit with a dry cloth or vacuum cleaner. Ensure ow and
humidity sensor areas are cleared of all dust.
DO NOT remove the top of the unit for cleaning.
Routine maintenance
All ventilation units require periodic maintenance. Routine maintenance must
only be carried out by a suitably qualied and competent person.
The Titon Ultimate®dMEV must be periodically cleaned internally. The dMEV
includes an airow sensor which monitors the ow rate and adjusts the speed to
maintain this ow
Excessive dust or other contaminants may impair the sensor accuracy. Cleaning
(e.g. Vacuum clearer) is recommended to remove dust from the fan housing and
ow sensor.
The sensor is a plug in service replaceable part, running issues due to sensor
clogging are not therefore covered under the product warranty.
18

Troubleshooting
Error Messages
The Display will alternately ash the messages to indicate a problem. If the fan
appears to be continually running fast see Routine Maintenance.
Fault checking must be carried out by a suitably qualied and competent person
Fan fault. Check for blockage.
Humidity sensor Fault.
Service replaceable part
Power supply fault.
Check fan cable connection to PCB.
Motor current too high. Contact
manufacture or its service agent
