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 AIR+PIV/L model Only 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.
The fan will run in 'Trickle' speed when the ambient loft temperature is
less than 18°C (adjustable via the Trickle Speed Temperature Threshold
setting).
The fan will run in 'Energy recovery' speed when the ambient loft
temperature is between the Trickle Speed Temperature setting (default
18°C) and Temperature Limit setting (default 27°C).
If the ambient loft temperature exceeds the Temperature Limit setting

The heater (if applicable) will activate when the ambient loft temperature is
below the Heater Threshold Temperature set point (default is 10°C). The set
point can be adjusted between 5°C and 20°C. The heater is designed to try and
maintain the heater set point temperature, however will depend on the chosen
flow rates and temperature of the incoming air.
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 AIR+PIV/L model Only. This data is non-
resettable.
