APPLICATION 
The SANO Intelligent PIV Loft is a loft mounted ultra quiet, low energy, low maintenance, home ventilation unit.
 
The unit is designed to help ventilate a home using the well-established Positive Input Ventilation (PIV) principle.
 
PIV units have been preventing and curing condensation dampness related problems in homes for decades. They are also used to control other indoor air pollutants and have even proven to be an effective means for reducing Radon gas in some properties.
 
OPERATION 
 
External air is drawn into the loft by the SANO PIV Loft unit. Before it passes through the unit’s filter, the air increases in temperature as it utilises otherwise unused energy in the loft from solar gain and heat loss from the home. This increase can be significant, but is typically around 3°C warmer than outside air over a heating season. This energy gain is significantly more than the energy used by the unit’s motor. The tempered, filtered air is then supplied centrally to the home via the unit’s outlet duct and ceiling diffuser.
 
Integral controls allow the SANO PIV Loft unit to be set to suit the individual requirements of the home. Airflow from the unit to the home is automatically regulated via an integral temperature sensor which optimises the energy benefit of the unit while ensuring that sufficient air is always supplied to help control moisture and other pollutant levels in the home.
 
FEATURES & BENEFITS 
Discreet Small white plastic supply air diffuser which will blend well with any ceiling while distributing the air as required.
 
Low energy Ultra-low quiet fan/motor assembly.
 
Robust and lightweight Fan casing construction built to last.
 
Low maintenance Very large G4 grade filter.
 
Integral, multi-functional controls With wide airflow and temperature settings which allow the unit to be fine-tuned to suit the individual requirements of a home and its occupants. These controls include:
• 8 unit settings to choose from to suit the size, layout, thermal properties and moisture production in the home.
• Heat Recovery or Comfort Control mode function with adjustable trigger temperature setting and adjustable increased/decreased airflow setting.
• Standby mode which switches the unit off when the temperature reaches the pre-set “Standby” trigger temperature to save energy and prevent undesirable warm air being introduced unnecessarily in to the home. e.g. during hot summer days.
• Override Boost mode to operate the unit at its maximum airflow by means of a user switch.
 
Suspension kit and joist mounting brackets Supplied for use as required.
 
Warranty Each SANO IPIV Loft H has a 5 Year Warranty as standard.*
 
PERFORMANCE DATA
 
Unit Setting The unit setting is selected by the installer to suit the size, layout, thermal properties and moisture production in the home. 
 
Normal The unit will run in this mode for the vast majority of its operational time until the unit’s integral sensors switch it to Eco-LoFlo, Heat Recovery, Comfort Control or Standby mode or the Override Boost mode (if connected via a suitable switch) is activated by the occupants.
 
Heat Recovery
The unit will increase in speed when the loft temperature reaches the Heat Recovery trigger temperature to supply even more warmed air from the loft into the home. Comfort Control This mode can be selected as an alternative to Heat Recovery mode above. In this mode the unit will decrease in speed when the loft temperature reaches the
 
Comfort Control
This mode can be selected as an alternative to Heat Recovery mode above. In this mode the unit will decrease in speed when the loft temperature reaches the Comfort Control trigger temperature reducing the amount of warm air entering the home.
 
Standby The unit will essentially switch off when the loft temperature reaches the Standby trigger temperature to save energy and prevent undesirable warm air being introduced unnecessarily into the home e.g. during hot summer days. This function can be disabled if continuous running is required e.g. radon gas control.
 
Override Boost The unit’s automatic controls can be overridden to operate the unit at its maximum airflow by means of a user switch hard wired to the relevant connections within the unit.
