DESIGN AND OPERATING LOGIC

The unit consists of a telescopic duct with adjustable length, a ventilation

unit and an outer ventilation hood.

Two lters and a ceramic heat accumulator (regenerator) are installed

inside of the telescopic air duct. The round Ø 150 mm air duct is made of

plastic and has an adjustable length:

– 240 up to 460 mm for the models VENTO A50 / A50-1;

– 120 up to 420 mm for the models VENTO A50 S / A50-1 S.

The unit is equipped with a high-tech ceramic heat accumulator with

regenerating eciency up to 91%. Due to the cellular structure is has larger

contact surface and higher eciency. The heat accumulator is featured with

excellent heat-conducting properties and thermal energy storage capacity.

The ceramic heat accumulator is used for extract air heat energy recovery

for warming up of supply air. The cord inside the regenerator facilitates its

removal for maintenance. The regenerator is installed on the insulation

material used as a sealer as well.

The ventilation unit must be installed on inner side of the wall. It is

equipped with automatic shutters that close the air duct when the unit is o.

Air is supplied and extracted with an axial reversible EC-fan with low

energy demand. The motor has overheating protection and ball bearings for

longer service life.

Two built-in lters with total lter class G3 are used for supply and extract

air ltration and the regenerator anti-soiling protection.

The outer ventilation hood must be installed on outer side of the building

to prevent ingress of large objects and water into the unit.

The integrated automation enables two-speed operation of the unit

(minimum or maximum speed):

– ventilation mode (air supply or air extract);

– reversible operation mode with heat regeneration.

The external control and power unit SEA-T12 or the control panel SEA is

used for operation mode control.

The delivery set of the units VENTO A50 Pro / A50-1 Pro / A50 S Pro / A50-1

S Pro includes the control and power unit SEA-T12 consisting of the control

panel SEA and the 12W transformer AT-12.

The single control and power unit SEA-T12 enables connection up to 4

units and their integration into a central controlled ventilation system.

The following components are required to arrange a central controlled

ventilation system consisting of from 4 up to 12 ventilation units:

– required number of VENTO A50 units (no control unit is included);

– control panel SEA;

– 40W power transformer AT-40.

2. Ventilation mode (air supply or air extract) at second speed.

3. Reversible mode (regeneration) at rst speed.

4. Reversible mode (regeneration) at second speed.

In regeneration mode the unit operates in 2 cycles, 70 seconds each.

Cycle I. Warm stale air is extracted from the premise, ows through the

ceramic regenerator and transfers its heat energy. In 70 seconds the

ceramic regenerator gets warmed up and the unit is switched to the

supply mode.

Cycle II. Clean cold intake air ows through the regenerator, absorbs

humidity and is warmed up with the accumulated heat. In 70 seconds

the ceramic regenerator is cooled down and the unit is switched to the

extract air mode. The cycle begins anew.

Two control channels are used for connection of Vento A50 units to the

control panel SEA. Such design solution provides exibility during connection

of several Vento A50 units.

The impeller rotation direction at start of the regeneration mode or in

ventilation mode is determined by positioning the jumper JMP1 on the

ventilation unit circuit board. The jumper positioned in «Flow In» position sets

the unit to supply mode and the jumper positioned in «Flow Out» position

sets the unit to extract mode.

The VENTO A50 is connected to the control panel SEA with a ve-wire cable.

The wire colour marking corresponds to the supplied cable. The minimum

conductor cross section is 0.25 mm2(23 AWG).

Type and power of the step-down transformer T1 is selected to provide 12 V

alternatingcurrentvoltageand3W powerconsumptionofeachVentoA50unit.

Separate power supply (230 V / 50 Hz or 120 V / 60 Hz) must be connected

both to the control unit SEA (SEA-Т) and to the ventilation unit to enable

actuation of the automatic shutters (socket connectors 31-32 in each case).

All electric connection to the control unit and the ventilator are performed

with the socket connectors (detachable terminal blocks) for mounting and

servicing facilitation. Each mating part of the socket connector has colour

marking in compliance with marking on the circuit board to ensure correct

and quick electric installation.

The control panel SEA is used to set one of four operation mode of the unit,

g. 17:

1.Ventilation mode (air extract / air supply)* at the rst speed with air ow 26 m3/h.

2. Ventilation mode (air extract / air supply)* at the second speed with air

capacity 53 m3/h.

3. Reversible (regeneration) operation at the rst speed with air ow 26 m3/h.

The unit changes air ow direction every 70 seconds.

4. Reversible (regeneration) operation at the second speed with air ow 53 m3/h.

The unit changes air ow direction every 70 seconds.

* - air ow direction depends on position of the jumper JMP1 on the

circuit board. The jumper is set to supply mode by default, g. 18.

Up to 12 Vento A50 units may be connected to a single SEA control panel

powered by the 40W power transformer AT-40, g. 20.

First connect the 12W transformer wire leads to the contacts A1:35, 36 of the

controller A1 (SEA) using the socket connector at the cable K2. The cable is

included into delivery set of the 40W transformer model.

Then connect the rst unit A3-No.1 to the contacts A1:11-15 of the controller

SEA using the connecting cable supplied with the rst unit. Connect the

second unit A3-No.2 (contacts A2: 21-25) to the rst unit (contacts A2: 11-15)

using the connecting cable supplied with the second unit.

Connect all the other units, up to 12 items, in the same way.

Connect power supply (230 V / 50 Hz or 120 V / 60 Hz, depending on the unit

model) to the contacts A2: 31,32 of each unit.

The fan impeller rotation direction is determined by position of the jumper

JMP1 on the PCB of A2 unit: the leftmost position sets the unit to extract mode

(Flow Out) and the rightmost position sets the unit to supply mode (Flow In).

The jumper is used to set direction for each fan in the group. The transformer

unit is connected to power mains through the power cable with a plug, which

is prewired to the transformer unit terminal block by the manufacturer.
