Product Information
HRV3
The HRV ECOaura are Mechanical Ventilation with Heat Recovery (MVHR) units. They are designed for the energy ecient
ventilation of dwellings. The units are designed for continuous ventilation, exhausting stale moist air from bathrooms,
toilets, kitchen and utility rooms. As the stale air is extracted, the unit’s heat exchanger transfers heat, which would have
been wasted, to the fresh air being supplied to the bedrooms and living rooms.
aura-t
The aura-t is a programmable touch screen controller which monitors and displays the status of a Titon ECOaura HRV
unit. It allows the unit to be commissioned, and gives the user both manual and timed control of fan speeds. The aura-t is
connected to the HRV via a low voltage connection and can be sited remotely from the unit.

with a battery backup.
Day of Week Display
The aura-t displays the days of the
week as numbers.
Timer
The aura-t has a programmable timer
that can be used to switch the HRV to
Speed 1 at specied times.
Status Icons
The aura-t displays icons to indicates
modes of operation in Real-time.
Filter Change Alert
The aura-t will display an alert after
a specied time when the HRV lters
require changing.
Multiple Internal
Temperature Sensors
The HRV measures From Atmosphere
and To Atmosphere air temperatures
in real-time. Additionally the
temperatures of the air extracted
from, and supplied to, the property are
monitored.
Internal Humidity Sensor
The HRV has a relative humidity
(RH) sensor. The RH sensor can be
programmed to switch the HRV into
Boost Speed.
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®.
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
The duct heater, EKA-NV160/1.5kW,
is installed upstream of the HRV unit
in the From Atmosphere insulated
ducting.
6

Frost Protection Program
Stage 1
Frost protection is achieved by the unit
detecting the outside air temperature
being drawn into the HRV and then,
below the trigger temperature,
enabling the duct heater. The duct
heater is then controlled proportionally
based on the temperature of the
exhaust air. This is pre-set to ensure
that the exhaust air temperature does
not fall below 2°C.
Stage 2
During very cold weather with the
duct heater activated, if the exhaust
air temperature falls below 0.5 degrees
C the duct heater will be de-activated
and the supply fan ventilation rate
stopped allowing the warmer air
extracted from the property to raise
the exhaust air temperature preventing
the formation of ice within the heat
cell. As temperatures rise the Frost
Protection Program will increase the
supply ventilation ow rate back to the
commissioned settings.
.
Shut Down of Supply Fan
This feature stops all ventilation and
overrides any other speed control
input when a problem with the exhaust
fan or associated ductwork causes
insucient warm air to be available to
heat the incoming air supplied to the
property. The sensor monitoring the
Supply Air into the property will stop
both fan motors when this temperature
measures below 5˚C.
The Frost program icon will ash and
the fan speeds will display 0%. The
unit will remain o until the fan key is
pressed or the temperature increases
above 5˚C.
When the fan key is pressed the
unit will restart at full speed and
settle back to normal operation after
approximately 40 seconds. If the air
supplied to the dwelling is still below
5˚C Shut Down of Supply Fan mode will
stop ventilation again.
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.
2 x Proportional Sensor
Inputs
Enables connection of environmental
sensors to the HRV which can be used
to proportionally control HRV fan
speeds.
