DESIGNATION KEY

TECHNICAL DATA

The temperature in the room where the indoor unit of the ventilator is installed must be in the range from +1 ˚C to +40 ˚C with relative humidity up to 65 % (no condensation build-up). The temperature of the transported air should be in the range from -15 ˚С to +40 ˚С. If the conditions of use of the ventilator are outside the specified limits, turn off the ventilator. Provide fresh air supply through windows. The unit is rated as a class II electric appliance. Ingress protection rating against access to hazardous parts and water ingress is IP24. The type of hood supplied and the length of the duct depend on the model of the ventilator (see section Designation Key). The unit design is constantly being improved, thus some models may be slightly different from those described in this manual.

OVERALL DIMENSIONS OF THE INDOOR UNIT [MM]

DESIGN AND OPERATING PRINCIPLE

The ventilator consists of an indoor unit with a decorative front panel, a fan unit, a heat exchanger unit, located inside the air duct and the outer ventilation hood. In the VENTO inHOME mini and VENTO inHOME mini M models, the fan and heat exchanger units are combined in a single cartridge. Two filters are located inside the air duct in the airflow path to provide coarse air purification and prevent dust and foreign objects from entering the heat exchanger and the fan. In the bottom right corner of the front panel of the ventilator, there is a window for the IR remote control receiver combined with a light sensor. The light sensor controls the brightness of the control panel LEDs. The LEDs glow brighter during daylight hours and dimmer in the dark.

VENTILATOR DESIGN

• in all pictures of this manual, an AH-10 hood is depicted as an example; the ventilator may be delivered with different hood models.

VENTO inHOME (mini) (С1) (M)

Operating principle of VENTO inHOME, VENTO inHOME C1 and VENTO inHOME mini ventilator shutters The indoor unit is equipped with automatic shutters. During the ventilator operation the automatic shutters are opened and let the air flow freely through the ventilator. It takes 2 minutes for the shutters to close upon ventilator shutdown. The process of opening and closing the shutter can take up to five minutes. Attention! The unit is equipped with a shutter fixer (pos. 1). In the event of a power failure, the product shuts down but the shutters remain open. If necessary, you can close the shutters. To do this, remove the front cover and press the push rod (item 2) in the direction of the arrow. This releases the push rod and the shutters close. The product is equipped with a shutter position sensor. When power is restored, the sensor detects the position of the shutters and opens them if the product has been running or closes them if the product has not been running. The shutter opening/closing mechanism operates with a delay of 1 to 5 minutes after the unit is switched on or off. The indoor unit of the VENTO inHOME M and VENTO inHOME C1 M ventilators does not have shutters. The air duct in these models can only be blocked by pushing the front panel of the ventilator as far as it will go, as shown in the figure below. The figure below shows the position of the shutters in the closed and open positions.

Opening/closing the airflow
To open the air duct, gently pull the front panel towards you with both hands. The ventilator’s fan will automatically be set to the speed of the current ventilation mode. To close the air duct, gently press down on the front panel until the air duct is completely closed. The ventilator’s fan will turn off automatically. The function of the ventilator is not impacted during the procedure.

VENTILATOR OPERATION MODES

• Ventilation: the ventilator runs either in air extraction or air supply mode at a set speed. In this mode some of the ventilators in the network run in air supply mode and the other ones in air extraction mode, depending on the DIP switch No. 3 position (see “Setting ventilator operation modes using DIP switches”).
• Boost – if the set humidity level is exceeded or the NO-contact of the external relay sensor is closed, the ventilator switches to the third speed until the sensors switch to their standard status and the Boost turn-off timer runs out.
• Regeneration: the ventilator runs in two cycles, 70 seconds each, with heat and humidity regeneration.
  • Cycle I. Warm stale air is extracted from the room and flows through the ceramic regenerator, which gradually absorbs heat and humidity. In 70 seconds, as the ceramic regenerator gets warmed, the ventilator is switched to air supply mode.
  • Cycle II. Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture and is heated up to the room temperature. In 70 seconds, as the ceramic regenerator gets cooled down, the ventilator is switched to air extraction mode and the cycle is renewed. The starting interval of a specific ventilator depends on the position of the DIP switch No. 3. If two ventilators – an even number of them – are installed, they must be set to operate with opposite rotation directions. While one ventilator supplies air, the other one extracts it.

When simultaneously activating several operation modes that exclude each other, the ventilator selects the mode according to the following priority:

1. Night mode timer or the Party mode timer
2. Standby
3. Boost
4. Standard operation mode

MOUNTING AND SET-UP

• READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT
• DO NOT BLOCK THE AIR DUCT OF THE INSTALLED VENTILATOR WITH DUST-ACCUMULATING MATERIALS, SUCH AS CURTAINS, CLOTH SHUTTERS, ETC. AS IT PREVENTS AIR CIRCULATION IN THE ROOM.

The figure below shows a schematic layout of the ventilator’s internal elements depending on the wall thickness. The ability to mount the ventilator in the wall depends on the length of the internal elements and the required protrusion A. The length of the internal elements, the diameter of the required opening and the minimum wall thickness in which the ventilator can be installed when using different external ventilation hoods are shown in the table below.

    Insert the sound-absorbing layer into the air duct. Roll the layer of the sound-absorbing material to match the air duct diameter. The protecting paper layer must be outside. Insert the sound-absorbing roll into the cartridge to match the slot. Make a mark at the end of the air duct, remove the material and cut the roll as marked. Insert the ready sound-absorbing roll into the air duct.

11. Install the front part of the indoor unit.

CONNECTION TO POWER MAINS

The ventilator is rated for connection to AC 100-240 V/50 (60) Hz power mains. For electric installations use insulated, flexible conductors (cables, wires) with a minimum cross-section of 0.5 up to 0.75 mm2 for power cables and 0.25 mm2 for sensor cables. The cable cross section is given for reference only. While selecting the required cable cross section consider the cable type, its maximum heating temperature, insulation, length, and installation method. Use copper wires for all the electric connections! Connect the unit to power mains via the terminal block installed in the controller board in compliance with the wiring diagram and terminal designation. Connect the unit to power mains through the external automatic switch with a magnetic trip integrated into the fixed wiring system. The tripping current of the circuit breaker is selected based on the electrical characteristics shown on the label of the fan casing. The ventilator design enables connecting any external controls with normally opened contacts (NO-contact), such as an external CO2 sensor, a humidity sensor, a switch, etc. When the NO contact of the external device is closed, the ventilator switches to the maximum speed.

EXTERNAL CONNECTIONS DIAGRAM

• The circuit breaker is not included in the delivery set.

Grouping the ventilators in a network
For group control over multiple ventilators, they need to be grouped in a network. A possible network grouping example is illustrated in the figure below. The ventilators can be connected in series and branching chains (ventilators No. 2 and No. 3 in the figure).

• Warning! Do not connect more than two input cables to a single output when branching! The network can only have one Master ventilator (it is determined as the one, whose IN-terminal is not connected).
• Warning! The diagram in the figure below is an example intended to explain the possibility to connect ventilators for group control. Each installation requires the layout to be determined based on the relative positions of the ventilators.

VENTILATOR SETUP
Prior to operating the ventilator set up the ventilator using the DIP switch. It is located on the controller circuit board. To access the DIP switch, take off the front panel of the indoor unit and uplift the rubber plug that covers the switch.

Positioning of the DIP switches

VENTILATOR CONTROL
The ventilator is controlled with the remote control or keys on the side surface of the indoor unit (see the figure below). When ventilators are connected in a single network, the controls only impact the first (Master) ventilator.
