Auto Setback Speed
Setback Speed is a reduced ventilation rate. Auto Setback Speed is automatically
set at the mid point between minimum possible Continuous Speed and the
selected Continuous Speed. The Auto Setback Speed can be enabled by
connection of a volt-free one-way switch, or combined with the Boost Speed with
the 3 position switch TP 508.
Setback Speed
Setback Speed is a reduced ventilation rate. Setback Speed is congured using
a step-less independent fan control potentiometer. The Setback Speed can be
enabled by connection of a volt-free one-way switch, or combined with the Boost
Speed with the 3 position switch TP 508.
Continuous Speed
Continuous Speed is the normal running speed of the unit. Continuous Speed is
congured using a step-less independent fan control potentiometer.
Boost Speed with Overrun Timer
Boost Speed is an increased speed providing higher extract air ow. Boost Speed
is congured using a step-less independent fan control potentiometer. The Boost
Speed can be triggered by any device which provides a volt-free one-way switch,
such as a PIR, thermostat, humidistat or a standard one-way switch
Boost Overrun Timer
Boost Overrun Timer maintains the Boost Speed for a specic time variable between
0 and 30 minutes. The Boost Overrun Timer time is congured using step-less
independent potentiometer.
Integrated Humidity Sensor
Some units are tted with an Integrated Humidity Sensor. This continuously
monitors the relative humidity (RH) of the extracted air and triggers Boost Speed
when the relative humidity rises over the set threshold. The Humidity Sensor’s
trigger point is variable from 55%RH to 85%RH and is congured using step-less
independent potentiometer.

Installation
Fixing
1. The unit must be securely xed to a
smooth at surface, any orientation
is possible.
2. Mark the four xing hole centres
using the Base as a template.
3. Drill holes for xings, use 4mm
Pan Head screws. Always use a
xing type and length suited to
the substrate type. The unit weighs
approximately 5kg.
4. Mount the Base, ensuring it is not
distorted by the xings or mounting
surface.
5. Clip the Motor and Lid assembly to
the Base, ensure that all 6 clips have
engaged.
Tighten screws by hand, DO NOT over
tighten screws or use power tools.

Ducting Connections
Titon recommend the use of guidance given in the Domestic Ventilation
Compliance Guide 2010 Edition ISBN-978 1 85946 378 9 and
Approved Document Part F 2010 ISBN-978 1 85946 370 3 for all
installations in the United Kingdom.
The above documents can be downloaded free from www.planningportal.gov.uk.
Titon recommend that:
1. 204 x 60mm ducting is used for the
connection of the Extract Port to
Outside.
2. 204 x 60mm or 110 x 54mm ducting
is used for connection to the other
ports.
3. A minimum distance of 200mm
between the CME1 Q Plus unit and
any sharp bends in duct work.
4. Ducting should be insulated where
it passes through unheated areas
and voids.
5. Unit should be insulated when
tted in unheated area.
6. Where a duct extends externally above roof level the section above the roof
should be insulated or a condensate trap should be tted just below roof level.
7. Where ducts pass through re barriers, they must be appropriately re stopped
in accordance with the requirements of Part B Building Regulations (England &
Wales).
8. A ducting condensate drain must be tted to vertical Extract Port to Outside
duct work.
9. Condensate drain pipe work must be adequately secured, installed to have
a minimum 5° fall and be insulated if any part of the pipe passes though an
unheated void.

10. All insulation to be the equivalent of
at least 25mm of insulating material
with a thermal conductivity
of 0.04 W/(mK).
11. Ducting must be installed in such
a way that resistance to airow is
minimised.
12. Ducting connected to the Extract
Port to Outside must be to the
external air outside the building
envelope.
13. All ducting joints including those
to the CME1 Q Plus unit’s Duct Ports
and Convertible Port Covers must
be permanently connected and
sealed.
14. Do not distort ducting, Convertible
Port Cover or Duct Ports.
15. 204 x 60mm ducting ts inside the
units Duct Ports.
16. 110 x 54mm ducting ts inside the
Convertible Port Cover.
17. Unused extract ports must be tted
with non-converted or undamaged
port covers.

13
How to Convert Port Cover
1. To enable tment of 110 x 54mm
ducting, modify the Convertible
Port Cover by tearing out the ‘rip
strip’.
2. When using the convertible port
cover ensure the tear out section is
completely removed.

Wiring Regulations and all applicable standards and Building Regulations.
1. Electrical installation of the appliance MUST be carried out by a suitably
qualied competent person.
2. Inspect the appliance. If damaged, it must be replaced by the manufacturer,
their service agent or similarly qualied persons in order to avoid a hazard.
3. The appliance must be connected to a local double pole isolation switch with a
contact separation of at least 3mm. Ideally located adjacent to the unit.

Commissioning
TP300A & 301A
The fan speeds of the Titon CME1 Q Plus will require adjustment to ensure that the
ow rates achieved provide adequate ventilation. The Titon CME1 Q Plus has 3
standard fan speed settings, Continuous Speed, Boost Speed and Setback Speed.
The Continuous Speed and Boost Speeds are adjustable via Rotary Potentiometers.
Setback Speed is automatically set at the mid point between minimum possible
Continuous Speed and the selected Continuous Speed.
Prior to the rst commission, set the Continuous Speed potentiometer to minimum
by rotating fully anti-clockwise and set the Boost Speed potentiometer to maximum
by rotating fully clockwise.
Control Parameters
All volt-free switch inputs are disabled when the Program / Run Header Link is
in the Program position.
All speed control potentiometers are disabled when the Program / Run Header
Link is in the Run position.
The unit needs to be powered up for the commissioning settings to be stored.

Q Plus will automatically switch
between Continuous Speed and
Boost Speed when adjusting the
respective potentiometer.
2. Rotate Continuous Speed

achieve required continuous air
ow.
3. Rotate Boost Speed adjustment
potentiometer to achieve required
boost air ow.
4. Return Program / Run Header Link
to Run Position, tted to one pin, to
exit commissioning.
After commissioning the Program / Run
Header Link must be placed in the
Run position.
Alternatively the Program / Run Header
Link can be completely removed to
‘lock’ the commissioned settings.

Boost Overrun
Boost Overrun Timer is variable between
0 and 30 minutes. Rotate potentiometer
to change overrun time. Boost Overrun
Timer adjustment can be done at any
time without the need to move the
Program / Run Header Link.
Controller Reset
Following a controller reset the ventilation system will need to be fully re-
commissioned. The unit will need to be powered up during the reset procedure.
1. Place the Program / Run Header Link in the Run Position
2. Rotate the Continuous Speed and Boost Speed adjustment fully clockwise.
3. Place Program / Run Header Link in the Program Position.
4. Rotate the Continuous Speed adjustment potentiometer fully anti clockwise.
Hardware Reset
Certain conditions (repeated supply interruptions etc.) can activate the automatic
motor protection mode. Where by the fan motors are prevented from operating.
This requires a hardware reset to return the unit to normal operating mode, to
achieve this power to the unit should be switched o for 5 minutes, restoring
the power after this time will reset the hardware of both the motor and PCB.
Commissioning settings are not aected during a hardware reset.
