Product Features
CME3.1 Q Plus CH
The CME3.1 Q Plus CH is controllable by
various volt-free switches and sensors.
Mains switching can be achieved by use
of the Titon Boxed Relay 5A TP 505.
Mains switching No
Volt free switching Yes
Continuous Speed The normal running speed of the unit.
Continuous Speed is congured using a epless
independent fan control potentiometer
Boost Speed An increased speed providing higher extract
air ow. Boo Speed is congured using a
epless independent fan control potentiometer
Boost Switching The Boo Speed can be enabled by
connection of a volt free one-way switch,
or combined with the Setback Speed
with the 3 position switch TP508.
Boost Overrun Timer The timer maintains the Boo Speed for
a specic time variable between 0 and 30
minutes after Boo Speed is disengaged.
The Boo Overrun Timer time is congured
using epless independent potentiometer
Setback Speed The reduced ventilation rate is automatically
set at the mid point between minimum
speed and the selected Continuous Speed.

CME3.1 Q Plus CH
Setback Switching Is enabled by connection of a latching volt-free
one-way switch, or combined with the Boo
Speed with the 3 position switch TP 508.
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 & Boo Speed depending on the
measured %RH;

The Humidity Sensor’s set point is variable from
55%RH to 85%RH and is congured using a
potentiometer.

The auralite remote indicator panel
can optionally be connected to the unit.
auralite is a low voltage hard wired remote
LED ventilation syem atus indicator,
designed to t a andard UK patress or
recessed backbox. The indicator is for
use with specic Titon CME units. The
indicator has six LEDs which display

InstallationInstallation
Fixing
The unit mu be securely xed
to a single smooth at surface.
Any orientation is possible.
Locate a site for mounting the Titon CME3.1,
take into consideration the position of:
xThe rooms to be ventilated
xThe Electrical services
xThe exhau port orientation.
Ensure there is adequate access
for inallation and maintenance,
see Dimensions for sizes.
Securely mount the unit through the mounting
holes on the casing using the appropriate
xings for the subrate and the CME3.1.
Ensure the unit is not diorted 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 CME3.1'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 diance of 200mm
between the CME3.1 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 ju below roof level.
7. Where ducts pass through re barriers,
they mu be appropriately re opped in
accordance with the requirements of Part
B Building Regulations (England & Wales).
8. A ducting condensate drain
mu be tted to vertical Output
Port to Outside duct work.
9. Condensate drain pipe work mu be
adequately secured, inalled 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 lea 25mm of insulating
material with a thermal conductivity
of 0.04 W/(mK).
10. Ducting mu be inalled in such a way
that resiance to airow is minimised.
11. Ducting connected to the Output Port
to Outside mu be to the external
air outside the building envelope.
12. All ducting joints including those to
the CME3.1 unit’s Duct Ports and
Convertible Port Covers mu be
permanently connected and sealed.
13. Do not diort ducting, Convertible
Port Cover or Duct Ports.
1212

14. Ø125mm ducting ts inside
the units Duct Ports.
15. Ø100mm ducting ts inside the
Convertible Port Cover.
16. Unused extract ports mu 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.

WiringWiring
The supply connection to this unit is via
screw terminals mounted on the printed
circuit 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.

CommissioningCommissioning
The fan speeds of the Titon CME3.1 Q Plus
CH will require adjument to ensure that
the ow rates achieved provide adequate
ventilation. The Titon CME3.1 Q Plus CH has
3 andard fan speed settings, Continuous
Speed, Boo Speed and Setback Speed.
All speeds are adjuable via Rotary
Potentiometers. Ensure the PCB
Cover is securely tted before powering
up the unit to commission.
Control Parameters
xAll switch inputs are disabled
when the Commissioning Switch
is in the Program position.
xAll speed control potentiometers are
disabled when the Commissioning
Switch is in the Run position.
xBoo Overrun Timer & Humidity
Sensor adjument can be done at
any time without the need to move
the Commissioning Switch.
xThe unit needs to be powered up for the
commissioning settings to be ored.

Commissioning Controls
To place the unit into commission mode
move the Commissioning Switch to the
Program Position. The CME3.1 Q Plus CH
will automatically switch between Setback
Speed, Continuous Speed and Boo Speed
when adjuing the respective potentiometer.
1. Rotate the Speed adjument
potentiometer to achieve required
air ow for each speed.
2. Return Commissioning Switch to Run
Position to exit commissioning.
After commissioning the Commissioning
Switch mu be placed in the
Run position.
