HRV ECOaura 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 Frost Protection is operating in Off Mode the Supply fan is switched off 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.

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 Overrun time
has elapsed.
