Product Features
CME3 Q Plus A CME3 Q Plus HA CME3 Q Plus
HA LS
The CME3 Q Plus is controllable by various
volt-free switches and sensors.
Mains switching can be achieved by use
of the Titon Boxed Relay 5A TP 505.
The CME3 Q Plus
HA LS is controllable
by various mains
switches.

Yes Yes No
Continuous
Speed
The normal running speed of the unit.
Continuous Speed is congured using a stepless
independent fan control potentiometer
Boost
Speed
An increased speed providing higher extract air flow. Boost Speed is
congured using a stepless independent fan control potentiometer
Boost
Switching
The Boost 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.
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
The 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

Setback
Speed
The reduced ventilation rate is automatically
set at the mid point between minimum speed
and the selected Continuous Speed.
Setback Speed,
reduced ventilation
rate, is congured
using a stepless
independent fan
control potentiometer.
Setback
Switching
Is enabled by connection of a latching volt-free
one-way switch, or combined with the Boost
Speed with the 3 position switch TP 508.
Enabled by connection
of a latching mains
one-way switch,
or combined with
the Boost Speed
with the 3 position
switch TP 508.
Integrated
Humidity
Sensor
NA 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;

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

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.
