Setback Speed
Setback Speed is normally a reduced ventilation rate. Setback Speed is congured
using a stepless independent fan control potentiometer. The Setback Speed can be
enabled by connection of a latching mains 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 stepless 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 stepless independent fan control potentiometer. The Boost
Speed can be enabled by connection of a mains one-way switch, or combined with
the Setback Speed with the 3 position switch TP508.
Boost Overrun Timer
Boost Overrun Timer maintains the Boost Speed for a specic time variable between
0 and 30 minutes after Boost Speed is disengaged. The Boost Overrun Timer time is
congured using stepless independent potentiometer.
Integrated Humidity Sensor
The units are tted with an Integrated Humidity Sensor. This continuously
monitors the relative humidity (RH) of the extracted air. The fan speed increases
proportionally between Continuous Speed & Boost Speed depending on the
measured %RH; see below for details.
The Humidity Sensor’s set point is variable from 55%RH to 85%RH and is congured
using a 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 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 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 CME2 Q Plus LS 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.

15
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.

16
Wiring Connections Access
Access to the connections for mains supply, boost and setback switching is
via removing the Cover and the PCB cover. All cables must be secured with
clamps provided. PCB cover must be securely tted before commencement of
commissioning.

Commissioning
CME2 & 2.1Q Plus LS
The fan speeds of the Titon CME2 Q Plus LS or CME2.1 LSwill require adjustment to
ensure that the ow rates achieved provide adequate ventilation. The unit has 3
standard fan speed settings, Continuous Speed, Boost Speed and Setback Speed.
All speeds are adjustable via Rotary Potentiometers. Ensure the PCB Cover is
securely tted before powering up the unit to commission.
Control Parameters
All 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.
Boost Overrun Timer & Humidity Sensor adjustment can be done at any time
without the need to move the Program / Run Header Link.
The unit needs to be powered up for the commissioning settings to be stored.

Commissioning
Place the link into the Program Position,
i.e. tted over both pins. The unit will
automatically switch between Setback
Speed, Continuous Speed and Boost
Speed when adjusting the respective
potentiometer.
1. Rotate the Speed adjustment
potentiometer to achieve required
air ow for each speed.
2. Return Program / Run Header Link
to Run Position, i.e. 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.
