Features
The following gives an outline description for each of the product features.
Filter Change Alert
The aura-t will display an alert after a
specied time when the MVHR lters
require changing. Filters should be
changed yearly. Replacment lters
availbale from:
www.beamcentralsystems.com
Programmable Speeds
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.
Boost Inhibit
Boost Inhibit is used to prevent the
MVHR’s speed increasing. Boost Inhibit is
used in conjunction with a Timer event.
Speed Selection & Display
The unit speed can be manually selected
via the on screen 1, 2, 3 & 4 buttons/
icons which are also used to display any
automatically selected speed.
24 Hour Clock
The aura-t has a twenty four hour clock
with a battery backup.
Day of Week Display
The aura-t displays the days of the week
as numbers.
Boost Overrun Timer
A programmable timer that controls
the time the MVHR remains at Boost
Speed after all boost switches have been
released.
Internal Humidity Sensor
The MVHR has a relative humidity
(RH) sensor. The RH sensor can be
programmed to switch the MVHR into
Boost Speed.
Status Icons
The aura-t displays icons to indicates
modes of operation in Real-time.

7
User Interface
The aura-t is operated via a LCD touchscreen. The screen is backlit, the backlight
operates when the screen is touched.
Menu Tabs
The aura-t screen has three interactive menu screens which are selected via tabs at
the bottom of the touchscreen.

Run Mode
The aura-t controls the MVHR unit’s 4 programmable speed settings.
This is the Run Mode screen; use the number buttons to select the required fan
speed.
Press and Hold the [1] or [2] button to enable boost Inhibit, the
Padlock icon will display to indicate Boost inhibit is active.
Pressing and Holding either the [1] or [2] button again will disable
Boost Inhibit.
The current running speed will be indicated by the corresponding
number button being highlighted.
The time of day is also shown on this screen in 24 hour format along
with the days of the week; the current day is ringed.
Status Icons
If the fan speed is being controlled by an external switch, a sensor or the timer this is
indicated by an icon beneath the speed selection buttons being visible.
The icons are as follows:
An external switch is active and is holding the MVHR at the indicated
speed.
The speed the MVHR is running at is being controlled by the internal
humidity sensor or an external Proportional Input sensor

9
Other Icons
Other status icon that may be visible on the screen are listed below:
The lters need changing or cleaning, refer to the Settings Menu for
details of how to reset the timer.
Frost Protection, if this icon is constantly lit the temperature outside
is low and the speed of the MVHR Supply Fan has been reduced to
prevent damage to the Heat Cell. If the Frost icon and backlight
are ashing the indoor temperature is low and both fans will have
stopped. Tap any of the fan speed number buttons to restart the
fans. If the temperature is still too cold, Frost Protection will be
activated.
Summer Bypass is in operation, air from outside is being supplied
directly to the property without recovering heat from the Heat Cell.
This is often accompanied by SUMMERboost®, both fans switch to
Speed 4 to increase the rate fresh air is supplied to the property and
stale hot air is extracted.
Press & Hold the [4] button to cancel SUMMERboost®.
The Boost Overrun timer is active and is holding the MVHR at Speed
3; this follows an external Boost switch being deactivated or if
the internal Humidity sensor has put the unit into Boost and the
Humidity has reduced below the set-point.
The padlock icon adjacent to the Speed 3 button and accompanying
the timer icon indicates Boost Inhibit is active. The MVHR is being
held at Speed 1 by the timer and will not respond to external Boost
switches or the internal Humidity sensor; it is also not possible
to manually increase the speed the MVHR’s running speed.
Proportional Input sensors are not aected.
The warning icon ashing at the bottom of the screen adjacent to
the Fan icon indicates a fan failure has been detected; contact the
installer. If very high temperatures are detected inside the MVHR,
fan failure mode will be enabled to protect the MVHR from damage.

In order for the Summer Bypass to operate the temperatures of both the air being extracted from the
property and supplied from outside must be above their individual thresholds. If the temperature of the
Supply air is less than 1°C cooler than the Extracted air the Summer Bypass does not operate to prevent
the warmer air being supplied directly to the property.
SUMMERboost® Enabled Disabled Enabled
SUMMERboost® operates in conjunction with Summer Bypass and switches the fans to Speed 4. It can
also be disabled by a latching switch if tted.
Switch Inputs SW1 Kitchen Boost

SW3 SUMMERboost®
Disable
Switch options are: Kitchen Boost, Wet Room Boost, Speed 1, Speed 4, SUMMERboost disable. When
congured as Kitchen or Wet room Boost, the switch will use the associated Boost overrun and delay
times for that room.
Live Switch Inputs LS1 Kitchen Boost

Boost
Live Switch options are: Kitchen Boost, Wetroom Boost. Live Switches also use the Boost overrun and

Some control features documented in this manual may not be compatible with older
BEAM MVHR units.

axco MVHR Defaults
The table below details MVHR settings and defaults, which that the aura-t CANNOT
congure. During installation and commissioning they may be changed from the
default values by an alternate BEAM controller. There is space available in the table
where the installer should record conguration settings.

Min Max
Boost Delay Timer Kitchen 0 mins 60 mins 0 mins

If the Boost Delay Timer is set greater than zero momentary switches will not switch the MVHR into Speed 3 Boost. When using latching
switches the MVHR will not Boost until the Delay time has elapsed.

Summer Bypass Enable/Disable Enabled Disabled Enabled
Frost Protection Mode O Reduce O
Frost Protection Threshold -2°C 11.5°C 2°C
When Frost Protection is operating in O Mode the Supply fan is switched o when the temperature measured by the sensor on the to
atmosphere side of the heat cell drops below the Frost Protection Threshold. When operating in Reduce Mode the speed of the Supply Fan
is gradually reduced when the temperature drops below the threshold. At 4°C below the threshold it is stopped.
Duct Heater Enable/Disable Enabled Disabled Disabled
Duct Heater Mode Frost User Frost
Duct Heater Threshold -4°C 16°C 4°C
Duct Heater Hysteresis 1°C 10°C 1°C
When operating in Frost Mode the Duct Heater uses the sensor on the to atmosphere side of the Heat Cell and switches on 2°C above the
Frost Protection threshold. When operating in User Mode it uses the sensor on the from atmosphere side of the heat cell and the threshold
and hysteresis detailed above. In both modes the Duct Heater will be switched o if the Supply fan speed drops below 22.5% PWM.
Internal Humidity Boost On
RH Boost Overrun 1 min 60 mins 15 mins
RH Boost Hysteresis 1% 10% 1%
When the Humidity of the air being extracted from the property reaches the threshold congured by the aura-t the fans switch to Speed
3 Boost. They remain at Speed 3 until the Humidity has dropped below the threshold minus the hysteresis and the RH Boost Overrun time
has elapsed.

Lower threshold 800PPM
Upper threshold 1400PPM
If tted, Room Sensors are used to provide Demand Control Ventilation based on the environmental parameter they are measuring.
Below their lower threshold they have no eect on the ventilation rate; once the lower threshold is exceeded the fan speeds proportionally
increase from Speed 2, Continuous until the upper threshold is reached when the fans will be running at Speed 3, Boost. In addition to the
%RH and CO2sensor detailed above Air Quality and Temperature Room Sensors may be tted. With any Room Sensor the range of Demand
Control Ventilation will be dependant on the individual sensor’s characteristics and the thresholds congured by the installer.
