Installation and Wiring Instructions for the
Air+ Wall Positive Ventilation Unit.
INTRODUCTORY NOTES
The Unit is a positive input ventilation unit, designed to be installed on a wall of a
dwelling to continually supply filtered fresh air into the building. The system
consists of a fan unit with heater.
The Unit has an adjustable speed settings. These speeds are set during installation;
there are 4 pre-set speeds or an option allowing the speeds to be chosen manually from
10 L/s - 30 L/s. The Unit uses a sensor to monitor the supply temperature into the
room. If the ambient room temperature exceeds 27°C (adjustable during commissioning),
the unit will automatically switch to standby (no airflow), unless installed in radon
mode (selectable during commissioning).
All models are supplied with a heater; the element is activated by default when the
supply air temperature drops below the adjustable threshold. The heater will try and
maintain the supply air temperature at the threshold temperature. The threshold
temperature can be adjusted during commissioning.
The unit also incorporates a data logging function. This function will display total
runtime of system, energy consumption of the fan and energy consumption of the heater.
This data is resettable (when in data logging menu, hold the + and – button for 15
seconds until you see the word “RESET” on the display).
