Speed Settings
The Air+PIV has two speed settings, 'Trickle' and 'Energy Recovery'.
'Trickle' speed is automatically selected when the ambient loft
temperature is below the Trickle Speed Temperature Threshold setting.
Default setting is 18°C.
'Energy Recovery' is automatically selected when the ambient loft
temperature is between the Trickle Speed Temperature (default is 18°C)
and Temperature Limit setting (default is 27°C).
If the ambient loft temperature exceeds the Temperature Limit setting,
the fan automatically switches to standby (no airflow) - except when
Radon Mode is enabled. See Radon Mode below for more details.
If the input air is below -5°C the fan will switch to standby.
There are 5 pre-set speeds that can be selected based on number of bedrooms in
the property. For example, setting b03 being for a three bedroom dwelling.
Please see Fig.10 for the approximate flow rates at each setting.
Alternatively, the speed settings are also fully adjustable between 10L/s and
60L/s via the manual speed setting option.

*The table shows a set up representative of a good low resistance installation
using the supplied filters. When F7 filters and/or a long duct run are used it
may be necessary to use the manual speed selection to meet the required flow
rate.
The Air+PIV must be set to provide adequate ventilation according to Part F of
the building regulations.
Heater Threshold Temperature
This is the temperature at which the heater will switch on. Default is 5°C.
The higher the temperature setting/threshold, the more energy the heater will
use. However the lower the setting, the colder the air will be supplied into
the house. The heater modulates (switches on/off) to maintain the set heater
threshold temperature.

commissioning as a pass code is required to access the menu. This can be set
in the menu to any 3-digit hexadecimal combination.
If the lock feature is enabled; when a button is pressed the display will

until the first digit is correct then press SET to move to the next digit.
Repeat until the code is entered and press SET to enter the commissioning
menu. If the code is entered incorrectly, wait until the screen switches off
then press any button to begin again.
Radon Mode
Radon mode keeps the fan running even at high temperatures to prevent the
build-up of dangerous radon gas in the property. If this is not required, it
is recommended not to use this setting.
