The SANO Intelligent PIV LOFT H 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. Our range of SANO Intelligent PIV units, with their unique ECO-LoFlo energy and comfort optimisation airflow control technology, represents a ‘step change’ in PIV technology.

External air is drawn into the loft by the SANO Intelligent PIV LOFT H 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 Intelligent PIV LOFT H unit to be set to suit the individual requirements of the home. Airflow from the unit to the home is automatically regulated via integral temperature and humidity sensors which optimise 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.

The SANO Intelligent PIV LOFT H is fitted with an intelligent multicore heater that tempers incoming air when required. The temperature of the incoming air is selectable between 10°C and 20°C and the heater will always try and achieve this using the least amount of energy possible. The heater works in conjunction with our industry unique ECO-LoFlo technology to provide the best comfort level for the user in the most energy efficient way.

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 mode function with adjustable trigger temperature setting and adjustable increased 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.
• ECO-LoFlo function
• Override Boost mode to operate the unit at its maximum airflow by means of a user switch.

Performance

Standby mode – 0L/s – 1.3W. Override Boost mode – 87L/s – 36W. Energy rating: C
*The power consumption shown is Normal mode and is for the PIV running without the heater, these will increase significantly when the heater is enabled.
**Filter change interval is indicative, high pollution and use of Override Boost mode will affect filter life.
