Product Overview
Description
The aura-t is a programmable touch screen controller which monitors and displays
the status of a Titon HMB HRV unit. The aura-t gives the user manual control of fan
speeds and enables access to enhanced commissioning functions of the HRV.
Retrotted to standard HMB units (Compatible units have a socket on the
terminal box)
Supplied with a HMB unit, to enable remote siting of the aura-t.
Integrated into the unit (not available with H200)
Packaging Contents
Inspect the unit when taking delivery. Check the unit for damage and that all
accessories have been supplied.
Package supplied with:-
1 x aura-t controller.
1 x ~3m aura-t communication cable (not included with integrated versions).
1 x Product Manual.
Any shortages or damage must be immediately reported to the supplier.

Product Overview
Controls & Features
Standard aura-t or auralite ready
The standard units have the ability to run standalone with the built in controller
with potentiometer commission or connect either an aura-t controller for enhanced
control and commissioning or an auralite LED status indicator using a the plug in
connection.
Enhanced aura-t integrated or aura-t connected
These units use the aura-t, for control and commissioning, either integrated into the
front of the units or connected using a the plug in connection.
Unit Features
Feature Standard without aura-t Enhanced with aura-t
connected or integrated
Programmable
Speeds
The unit has 4 Speeds.
Speed 1, Setback - Reduced
ventilation. Setback Speed is
automatically set at the mid
point between minimum
possible Continuous Speed and
the selected Continuous Speed.
Speed 2, Continuous - Normal
ventilation.
Speed 3, Boost - Increased
ventilation.
Continuous & Boost speeds are
commissioned using the basic
controllers potentiometer
Speed 4, SUMMERboost® - Very
high ventilation. This speed is
set at 100%.
The unit has 4 programmable
speed settings, all speeds are
variable between 14-100%
and allow independent speed
setting of both supply and
extract ventilation rates
Speed 1, Setback - Reduced
ventilation.
Speed 2, Continuous - Normal
ventilation.
Speed 3, Boost - Increased
ventilation.
Speed 4, SUMMERboost® - Very
high ventilation.

Feature Standard without aura-t Enhanced with aura-t
connected or integrated
Speed Selection Speed 1, Setback is enabled by
connection of a volt free one-
way switch, or combined with
the Speed 3 Boost with the 3
position switch TP 508.
Speed 3, Boost 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.
As the standard units with the
additional functionality of:
Speeds 1, 3 & 4 can be assigned
to any of the volt free switch
inputs. The unit speed can also
be manually selected via the on
screen 1, 2, 3 & 4 buttons/icons
which are also used to display
any automatically selected
speed.
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.

the switches can be congured
to perform any one of the
following functions:
o Wet Room Boost - engages

Feature Standard without aura-t Enhanced with aura-t

SUMMERboost® An optional SUMMERboost® facility is available that allows both
the supply and extract fans to run at increased speed whenever
the Summer Bypass is activate.
By default SUMMERboost® is disabled by a Link Wire, see Wiring
Diagrams. Removal of the link wire will enable SUMMERboost®.
When SUMMERboost® is triggered 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.
Boost Overun
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.
Two independently congured
timers are available.
Wet Room & Kitchen
Boost Alert Only available with auralite®
LED status indicator.
The aura-t displays an alert if
a switch has held the HRV in
Boost for more than 2 hours.
Boost Inhibit Not available. Boost Inhibit is used to prevent
the HRV’s speed increasing

Only available with auralite®
LED status indicator.
The aura-t will display an alert
after a specied time when the
HRV lters require changing.
Eco Mode Not available. After a one minute period of
inactivity the LCD will switch

Real-time.
Fan Speed
Cloning
Not available. The current fan speeds can be
saved to the aura-t and copied
onto another HRV to reduce
commissioning time.
When an aura-t controller is connected to a Standard unit all the Enhanced features
are available and any setting changes made will be stored after the aura-t controller is
disconnected.
