Automated Touch Screen Overview
This digital controller has been specifically designed to ensure the best possible ventilation for
your home. The large screen is designed to measure the indoor air temperature using a high
precision built-in sensor.
The digital controller communicates your ventilation requirement to the intelligent fan control
board which is constantly sensing the air quality and adjusting the fan speed. By selecting the
ventilation requirement this control board will increase/decrease the amount of ventilation to
your house. The ventilation requirement is adjusted according to your Set Comfort
Temperature.
No further inputs or adjustments are required. Simply set and forget.

Frequently Asked Questions
Which ventilation rate should I choose?
•
Low ventilation is suitable for low occupancy numbers in the house and when total
ventilation requirements may be substituted with opening windows and doors
(summertime).
•
Medium Ventilation (default) provides the ideal ventilation requirements for an
average well-insulated home.
•
High Ventilation is suitable when there is a higher occupancy in the home or signs of
poor air quality due to increased moisture levels in the house (condensation).
•
Auto mode maintains the requirements of the three rates based on temperature in the
home. As well as providing the correct levels of ventilation, the system also tries to
normalise the indoor air temperature to the target comfort level set by the user.
I turned the controller off. Why does the system keep running?
When turning the controller off the fan enters a shutdown cycle which may take up to a
minute to turn off fully.
