Section HMB/HMBE Product Overview
Controls & Features
The HRV Q Plus HMB units are controllable by various volt free switches and sensors. The following describes the controls
and features of the HRV Q Plus units and how they are controlled. Ensure all controls are adequately labelled, indicating
their function clearly.
Filter Covers
The units are tted with removable lter covers on the front panel.
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.
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.
10

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.
Enthalpy humidity-recovery
Units with the E sux use an enthalpy heat recovery core that recovers some of the humidity as well as heat.

Commissioning Units HMB/HMBE
Controls
The fan speeds of the Titon HRV Q Plus will require adjustment to ensure the ow rates achieved provide adequate
ventilation. The Titon HRV Q Plus has 2 standard fan speed settings Continuous Speed and Boost Speed.
The Continuous Speed and Boost Speed are programmed by placing the controller into Program Mode via the Program/
Run Switch and changing the position of rotary potentiometers.
When applying power for the rst time, the unit can take up to four minutes to start operating.
Prior to the rst commission set Continuous Speed potentiometers to minimum and Boost Speed potentiometers to
maximum or reset the controller.
Control Parameters
The Boost Speed cannot be set lower than the Continuous Speed.
The Continuous Speed cannot be set higher than the Boost Speed.
All switching inputs are disabled when the Program/Run Switch is in Continuous or Boost positions.
Speed control potentiometers are disabled when the Program/Run switch is in centre Run position.
For the commissioning settings to be stored the unit needs to be powered up.
Continuous Supply & Extract Speeds:
1. Move Program/Run Switch to Continuous position.
2. Rotate supply fan Continuous Speed adjustment potentiometer to achieve required supply continuous air ow.
3. Rotate extract fan Continuous Speed adjustment potentiometer to achieve required extract continuous air ow.
4. Return Program/Run Switch to centre position to exit commissioning.
Boost Supply & Extract Speeds:
1. Move Program/ Run Switch to Boost position.
2. Rotate supply fan Boost Speed adjustment potentiometer to achieve
required supply boost air ow.
3. Rotate extract fan Boost Speed adjustment potentiometer to achieve
required extract boost air ow.
4. Return Program/Run Switch to centre position to exit commissioning.

Boost Overrun
Boost Overrun Timer is variable between 0 and 60 minutes. Rotate
potentiometer to change overrun time. This can be done at any time.
Humidity Sensor
The Humidity Sensor’s trigger point is variable from 55%RH to 85%RH. Rotate
potentiometer to change trigger point. Humidity Sensor adjustment can be
done at any time without the need to move the Program / Run Header Link.
Controller Reset
Following a controller reset the ventilation system will need to be
fully commissioned.
The procedure to reset the Titon HRV Q Plus controller is a simple three step operation. The unit will need to be powered
up during the reset procedure.
1. Rotate the Supply and Extract Continuous Speed potentiometers fully anti-clockwise.
2. Rotate Supply and Extract Boost Speed potentiometers fully clockwise move the Run/Program Switch from the Run
position to the Continuous position, from the Continuous position to the Boost position and back to the Run position.
To ensure that the reset switch movements are registered by the controller wait two seconds between each switch
movement. Controller reset is now complete.
Hardware Reset
Certain conditions (repeated supply interruptions etc.) can activate the automatic
motor protection mode. Whereby the fan motors are prevented from operating. This requires a hardware reset to return
the unit to normal operating mode, to achieve this power to the unit should be switched o for 5 minutes, restoring the
power after this time will reset the hardware of both the motor and PCB. Commissioning settings are not aected during a
hardware reset.

Section B/BC/BE Product Overview
Control & Features
The B, BC & BE units are programmable with Titon controllers.
Enthalpy humidity-recovery
Units with the E sux use an enthalpy
heat recovery core that recovers some
of the humidity as well as heat.
Boost Overrun Timer
A programmable timer that controls
the time the HRV remains at Boost
Speed after all boost switches have
been released.
Boost Delay Timer
A programmable timer which can be
used to delay the HRV running at Boost
Speed after a boost switch has been
activated.
Boost Inhibit
A programmed time period that
prevents the HRV switching into Boost
Speed or SUMMERboost®.
Internal Humidity Sensor
The HRV has a relative humidity
(RH) sensor. The RH sensor can be
programmed to switch the HRV into
Boost Speed.
Filter Change Alert
The unit can display a lter warning via
a connected controller
4 x Fan Speeds
The units have 4 programmable speed
settings. All speeds allow independent
speed setting of both supply and
extract ventilation rates
Summer Mode
Summer Mode operates by slowing or
stopping the supply fan. This reduces
the supply of From Atmosphere air
to the dwelling. Summer Mode is
triggered automatically or via a Volt
Free input. Summer Mode must not be
enabled or installed in dwellings where
open ue combustion appliances are
used.
SUMMERboost®
SUMMERboost® allows both the supply
and extract fans to run at full speed
whenever the Summer Bypass is
activated. By default SUMMERboost® is
enabled.
Summer By Pass
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
dwelling.
Duct Heater Control
To maintain ventilation ow rates
where prolonged periods of very low
temperatures occur, the facility for the
control of an electrically powered Duct
Heater is provided, MAX 1800W. The
Duct Heater is placed in-line between
the outside supply vent and the From
Atmosphere terminal on the HRV. In
these applications, the heater is used
to pre-warm the outside fresh air
supply before it enters the HRV.
2 x Proportional Sensor
Inputs
Enables connection of environmental
sensors to the HRV which can be used
to proportionally control HRV fan
speeds.
3 x Volt Free Inputs
Enables the connection of single pole
momentary switches, latching switches
or normally open relay contacts
to the HRV. These can be used to
switch between fan speeds or control
SUMMERboost® and Summer Mode.
2 x Live Switch Inputs
These inputs are used to switch the
HRV to Boost Speed via a switched live
input.
Frost Protection Program
During very cold weather, the Frost
Protection Program will detect
temperatures that could cause ice to
form inside the unit. It will reduce
or stop the supply ventilation rate,
thus allowing the warmer stale air to
raise the temperature within the unit
cell to such a level that prevents the
formation of ice. As temperatures
rise the Frost Protection Program
will increase the supply ventilation
ow rate back to the commissioned
settings.
Multiple Internal
Temperature Sensors
The unit measures From Atmosphere
and To Atmosphere air temperatures in
real-time. Additionally the temperature
of the heat cell is monitored.
