Defaults
The table below details HRV settings and defaults, which that the
aura-t
CANNOT configure. During installation and
commissioning they may be changed from the default values by an alternate Titon controller. There is space available in
the table where the installer should record configuration settings.

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

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 off if the Supply fan speed drops below
22.5% PWM.

When the Humidity of the air being extracted from the property reaches the threshold configured by the

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

If fitted, Room Sensors are used to provide Demand Control Ventilation based on the environmental parameter they are measuring.
Below their lower threshold they have no effect 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 CO
2
sensor detailed above Air Quality and Temperature Room Sensors may be fitted. With any
Room Sensor the range of Demand Control Ventilation will be dependant on the individual sensor’s characteristics and the thresholds
configured by the installer.
