Process
•Check the MVHR filters are clean (see manual for instructions of how to access).
•Check correct ceiling terminals are fitted and open at approx. the mid-point (i.e. minimum resistance).
The aura-t™ controller provides the owner with 4 speeds.
•Speed 1 - Generally referred to as SetBack, not generally used in the UK. Can be used for example to reduce the
speed when the property is vacant or when on holiday.
•Speed 2 - Continuous rate.
•Speed 3 - Boost Rate
•Speed 4 - Generally referred to as SummerBoost, enables the units speed to be increased when SummerBypass is
active.
Speeds 2 and 3 are generally used to meet the flow rates requirements defined within Approved Document F.
The following assumes that both Continuous and Boost rates are required, if boost is not required please ignore the
paragraphs referring to Boost (speed setting 3)

icon, this will put the unit into the Extract Boost setting mode, as
below. The figure pointed at below will be flashing.
•Using the up and down arrows, indicated below, change the speed to a level that will provide the expected flow
rate. The speed % will change as you increase / decrease.
•Measure the flow rates in the kitchen and all the wet rooms, totalling up the measured figures.
• If the total is greater than the required total Extract Boost dwelling rate*, slow the unit down
• If the total is less than the required total Extract Boost dwelling rate*, speed the unit up
• Keep changing the speed until the total required Extract Boost dwelling rate* is achieved
*As the rates are minimums aim slightly higher approx. 1-2 l/s
• Working away from the unit now adjust the ceiling terminals to achieve the individual room rates. If the
room rates cannot all be achieved the unit may need turning up slightly
• When complete lock the ceiling terminals in position
It is not uncommon for ceiling terminals to be removed and mixed up by the painters, a good idea is to mark the inside
of the terminal with the room it came from, this saves re commissioning.
