A. INTRODUCTORY NOTES
The Airtech Air+ PIV is a positive input ventilation unit, designed to be installed in
the loft of a dwelling to continually supply filtered fresh air into the building.
The system consists of a fan unit, a heater unit and a diffuser with a short length of
flexible ducting.
The Airtech Air+ PIV has two fully adjustable speed settings; 'Trickle' and 'Energy
Recovery'. These speeds are set during installation; there are 5 pre-set speeds or an
option allowing the speeds to be chosen manually from 10L/s to 60L/s.
The
Airtech
Air+
PIV
uses
a
sensor
to
monitor
the
temperature
in
the
loft,
automatically adjusting the air volume when necessary.
'Trickle' speed is automatically selected when the ambient loft temperature is less
than 18°C.
'Energy Recovery' is automatically selected when the ambient loft temperature is
between 18 and 27°C.
If the ambient loft temperature exceeds 27°C, the Airtech Air+ PIV will automatically
switch to standby (no airflow).
For the heater unit, the element is activated by default when the loft air temperature
is below 10°C; the system will then work to maintain an input air temperature of 10°C.
This temperature threshold can be adjusted between 5°C and 20°C during commissioning.
The heater unit can be installed either to the fan unit or directly to the diffuser
spigot.
The unit also incorporates a data logging function. This function will display total
runtime of system, time spent in trickle speed, time spent in Energy Recovery speed,
approximate energy consumption of the fan and approximate energy consumption of the
heater unit. This data is non-resettable.
