Frequently Asked Questions - PIV Soler & Palau

What is a PIV unit and how does it work?

PIV stands for Positive Input Ventilation. It draws air from the attic (where temperature is higher than outside), filters it, and supplies it into the dwelling via a hallway. It includes a pre-heating battery for cold seasons and automatic regulation based on attic temperature.

What is the difference between PIV and PIV BP models?

The PIV BP model includes a by-pass that allows taking air directly from outside when attic temperature exceeds 25°C, preventing reheating of the dwelling. The standard PIV model only draws air from the attic.

What type of filter does the PIV use and how often should it be replaced?

It uses a G4 filter that is oversized with 3 sides (270° coverage) to extend service life. Replace the filter when it becomes visibly dirty or according to the manufacturer's recommendations (typically every 3-6 months).

Can the pre-heating battery be turned off?

Yes, the battery operation is automatic but can be disconnected via an external switch (not supplied with the unit).

What are the operating schemes and how do they adjust airflow?

There are 4 operating schemes. Each scheme sets two airflow levels: one for attic temperatures below 19°C and one for above 19°C. For example, Scheme 1: 70 m³/h (below 19°C) and 100 m³/h (above 19°C). Scheme 4 runs at 210 m³/h regardless of temperature.

What is the maximum airflow capacity of the PIV?

The maximum airflow is 210 m³/h for the PIV model and 200 m³/h for the PIV BP model.

Is the PIV unit suitable for all dwelling types?

It is designed for dwellings where whole-house ventilation is not possible. For asymmetric dwellings, it is recommended to install an ECOAIR DESIGN ECOWATT extractor fan. For very leak-tight rooms, consider adding EC or ECA inlet valves above windows.

What are the electrical specifications of the PIV?

The unit operates on 230 V AC. The motor absorbed power is 9,500 W (PIV) or 10,500 W (PIV BP) at free discharge. Protection is IP20 and insulation class II.

How does the unit regulate temperature?

The PIV has two probes: Probe 1 measures attic temperature, Probe 2 measures supply temperature. The pre-heating battery activates when supply temperature is below 10°C (or 15°C). Attic temperature above 25°C stops the unit (or switches to outside air in PIV BP). Sensors can be disconnected to run at a fixed speed.

What is included in the box?

The box includes: the PIV unit, 1 supply valve (Ø 200 mm), 1 meter of flexible duct (Ø 200 mm), and a fixing kit with screws and silent-blocks.

ENERGY EFFICIENT

VENTILATION SYSTEM

Ventilation unit that provides supply ventilation in dwellings whose distribution does not allow use of whole house ventilation system.

The PIV unit draws air from the attic, where temperature is always higher than external air, passes air via a filter and supplies it into the dwelling via hallway below attic.

G4 filter is oversized (3 sides of the unit, 270°) to increase service life.

The unit includes 4 operating schemes with DC and low consumption motor, automatic regulation of airflows and electric battery that allows constant supply temperature.

Versions

• PIV: standard model
• PIV BP: model equipped with by-pass to take air directly from outside.

Configuration

• G4 filter
  • Electric battery of 500 W.
• Fan with DC motor.
  • Supply valve with ∅ 200 mm.
• 1m of flexible duct with ∅ 200 mm.
• 1 fixing kit (screw and silent-blocks).

PIV unit takes the air from the attic, where temperature is always higher than external air, passes air via a filter and supplies it into the dwelling via hallway below attic.

It has available a pre-heating battery for the new air, for cold seasons. If the attic temperature is higher than 25^ C, the ventilation stops.

PIV BP model has an outside air intake. If attic temperature is higher than 25^ C, the unit directly takes the air from outside to avoid reheating of the dwelling.

In addition to the ventilation unit, the product also includes:

• 1 supply valve with ∅ 200 mm.
- 1 m of flexible duct ∅ 200 mm.
- 1 fixing kit (screw and silent-blocks).

Recommendations for correct operation

In case of asymmetric dwelling it is advisable to mount a wall centrifugal extract fan ECOAIR DESIGN ECOWATT to improve the efficiency of the system.

In case of a very leak-tight dwelling or with any room with specific moisture problems, it is advisable to mount above the windows a inlet air of EC range or, in case of high noise level from outside, of ECA range.

INCORPORATED PRE-HEATING BATTERY

An electric battery of 500W pre-heats the new air when needed. The battery only operates when supply temperature (probe 2) is lower than 10^ C (or 15^ C if we look for greater comfort). The operation of the battery is automatic, but it can be disconnected via a switch (not supplied).

REGULATION

According to the operation scheme selected, the unit modifies its airflow depending on the attic air temperature (probe 1). When it exceeds 25^ , the unit can optionally stop its operation, avoiding excessive heating of the house.

Operating schemes	T < 19°C		T > 19°C

3 140 8,6 210 11,1
4 210 11,1 210 11,1

Sensors can be disconnected, if necessary, and this way the unit would operate at one speed.
