Installation
Fixing
The unit must be securely xed
to a single smooth flat surface.
Any orientation is possible.
Locate a site for mounting the Titon CME3,
take into consideration the position of:
xThe rooms to be ventilated
xThe Electrical services
xThe exhaust port orientation.
Ensure there is adequate access
for installation and maintenance,
see Dimensions for sizes.
Securely mount the unit through the mounting
holes on the casing using the appropriate
xings for the substrate and the CME3.
Ensure the unit is not distorted by
the xings or mounting surface.
The xing slots on the unit are 6mm wide,
it may be necessary to use washers to
prevent damage to the CME3's xing slots.
Tighten screws by hand, DO NOT over tighten
screws or use power tools.
Ducting Connections
Titon recommend that:
1. Ø125mm ducting is used for the
connection of the Output Port to Outside.
2. Ø125mm or Ø100mm ducting is used
for connection to the other ports.
3. A minimum distance of 200mm
between the CME3 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 Output
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. All insulation to be the
equivalent of at least 25mm of insulating
material with a thermal conductivity
of 0.04 W/(mK).
10. Ducting must be installed in such a way
that resistance to airflow is minimised.
11. Ducting connected to the Output Port
to Outside must be to the external
air outside the building envelope.
12. All ducting joints including those
to the CME3 unit’s Duct Ports and
Convertible Port Covers must be
permanently connected and sealed.
13. Do not distort ducting, Convertible
Port Cover or Duct Ports.
10

14. Ø125mm ducting ts inside
the units Duct Ports.
15. Ø100mm ducting ts inside the
Convertible Port Cover.
16. Unused extract ports must be tted with
not converted or undamaged port covers.
How to convert the Port Cover
To enable the Port Cover to be used
as an adaptor for 100mm ducting, use
a small screwdriver to tear out the tail
and centre section. Ensure the tear out
sections is completely removed.

Wiring
Wiring Connection Access
The supply connections differ between units.
Identify which connection style and ensure
that the correct instructions are used.
Access to the supply connections is
achieved by loosing the two captive
retention screws and removing the Lid.
CME3 Q Plus A & HA
The supply connection of this unit is via
a Connector Block; This is accessed by
removing the Connector Block Cover. To
remove the cover unclip from the Connector
Block. After supply connection has been
made and before powering up the unit the
Connector Block Cover MUST be retted.

The supply connection to this unit is via
screw terminals mounted on the printed
circut board (PCB), access is achieved by
removing the PCB Cover. To remove the PCB
cover remove the two small retaining screws
and the cover will lift. After supply connection
has been made and before powering up the
unit the PCB cover MUST be retted and
screwed in place, do not overtighten screws.

Commissioning
CME3 Q Plus A
The fan speeds of the Titon CME3 Q Plus
A will require adjustment to ensure that
the flow rates achieved provide adequate
ventilation. The Titon CME3 Q Plus A 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
xAll volt-free switch inputs are disabled
when the Program / Run Header
Link is in the Program position.
xAll speed control potentiometers are
disabled when the Program / Run
Header Link is in the Run position.
xThe unit needs to be powered up for the
commissioning settings to be stored.

The CME3 Q Plus A will automatically
switch between Continuous Speed
and Boost Speed when adjusting
the respective potentiometer.
2. Rotate Continuous Speed
adjustment potentiometer to achieve
required continuous air flow.
3. Rotate Boost Speed adjustment
potentiometer to achieve
required boost air flow.
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.
