Auto Setback Speed
Setback Speed is used to reduce ventilation rates. Setback Speed is automatically
set at the mid point between minimum possible Continuous Speed and the
selected Continuous Speed. 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 continuous extract and supply air ow running
speed of the units.
Boost Speed with Overrun Timer
Boost Speed increases the extract and supply air ow. Boost Speed is congured
with Step-less independent fan controls and includes an Overrun Timer variable
between 0 and 60 minutes. 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. If the unit is left Boost (latching switch) for longer than
2 hours the Overrun Timer is disabled meaning the HRV will return to Continuous
Speed as soon as the switch holding the unit in Boost is released.
auralite® Boost Alert
Boost Alert is a timer designed to prevent the HRV being inadvertently left in Boost
for long periods of time. Once the HRV is placed in Boost the timer is started and
after 2 hours Boost Alert will be activated. This is indicated by the Boost LED on the
auralite® Indicator Panel ashing. Once Boost Alert has been activated the Overrun
Timer is disabled meaning the HRV will return to Continuous Speed as soon as the
switch holding the unit in Boost is released.
10

Summer Bypass
Summer Bypass is designed to operate during hot periods where fresh air can be
vented straight into the property without being preheated by the extracted stale
air. Summer Bypass operation is automatically controlled. The Summer Bypass
mechanism diverts the stale air being extracted from the dwelling around the heat
cell so that its heat energy is not transferred to the fresh air being supplied to the
property.
SUMMERboost®
An optional SUMMERboost® facility is available that allows both the supply
and extract fans to run at full speed whenever the Summer Bypass is activated.
By default SUMMERboost® is disabled by a Link Wire, see Wiring Diagrams.
Removal of the link wire will enable SUMMERboost®.
When SUMMERboost® is trigged by Summer Bypass the increased fan speed can be
prevented either Manually or Automatically.
Manual - This is by means of a volt-free switch wired directly into the controller PCB.
Automatic - This is by means of a dedicated wall mounted room thermostat.
SUMMERboost® will only operate when the temperature has exceeded the
thermostat setting. Should the room temperature fall below the thermostat setting,
then SUMMERboost® will not operate.
11

Automatic Frost Protection
During very cold weather, Automatic Frost Protection will detect temperatures that
could form ice inside the unit. It will reduce the supply ventilation rate to prevent
ice build up within the heat cell. Automatic Frost Protection reduces the ow rate of
cold air, thus allowing the warmer stale air to raise the temperature within the heat
cell to such a level that prevents the formation of ice. As internal temperatures rise
Automatic Frost Protection will increase the supply ventilation ow rate back to the
commissioned settings.
Integrated Humidity Sensor
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.

Do not remove the Port Covers until connecting ducting. Port Covers are tted to
prevent debris falling into the unit and causing blockages and damage:
The Titon HRV10 Q Plus is designed to be mounted on a wall or similar. The
mounting surface must be
suciently strong to support the
unit.
Consider the positioning of
electrical services and the
Condensate Drain when siting the
unit.
Ensure there is sucient access
around the HRV10 Q Plus for future
maintenance.
Do not ‘box-in’the unit making
access to the unit dicult for maintenance and repair.

The Unit Must be mounted plumb and level front to back and side to side.
1. Mark a horizontal line on the wall
using a spirit level. This line will be
approximately 330mm below the
location of the top face of the unit
when tted (excluding duct ports).
2. Use one of the Mounting Brackets
as a template to mark the three
xing hole centres.
3. Drill holes for xings, always use a
xing suited to the wall type.
4. Fix one Mounting Bracket to the
wall ensuring the interlocking side
is at the top, as shown. Mounting Bracket highlighted

6. Ducting should be insulated where it passes through unheated areas and
voids with the equivalent of at least 25 mm of a material having a thermal
conductivity of ≤0.04 W/(m.K) to reduce the possibility of condensation
forming. 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 of the Building Regulations (for
England & Wales).
8. A ducting condensate drain must be tted to vertical To Atmosphere duct
work.
