SYSTEM OVERVIEW


2 System overview

The MZ-One controller is an electronic control unit for inVENTer® decentralised mechanical ventilation units with heat recovery. The MZ-One controller can be used to control up to:

• 16 iV-Smart ventilation units with up to 4 ventilation units per Clust-Air module• 16 iV14 ventilation units with up to 4 ventilation units per Clust-Air module• 8 iV25 ventilation units with up to 2 ventilation units per Clust-Air module• 8 iV-Twin ventilation units with up to 2 ventilation units per Clust-Air module

It provides excellent Clust-Air® technology (multi-zone control), easy installation, an operating concept via touch, and its versatility of use.

The MZ-One controller consists of an MZ-One programming unit and between one and four Clust-Air modules. Each Clust-Air module controls the ventilation units of its designated area (zone) within a residential unit. Thus, the MZ-One controller provides separate ventilation for up to four diferent areas within the residential unit. For each deined zone, the operating mode and output level can be set by means of the 7-day timer or manually.

The controller can be used either as a base module or with additional sensors connected. An external interface allows the connection of a potential-free switching contact or integration into an existing home automation system via an analogue input.

The connected ventilation devices can be controlled in the following modes:

• Heat recovery • Dehumidiication• Ventilation • Sleep timer

The software is available in two languages.

Optionally, a CO2 sensor can be purchased as an accessory from inVENTer GmbH.

Features

• Intelligent Clust-Air® technology provides control of up to four diferent areas (zones) within one residential unit

• Visually discreet due to lush-mounted modules• Backlit display unit• Easy operation by means of touch-sensitive keys (navigation arrows)• Control of the ventilation devices in four operating modes:

Heat recovery, Ventilation, Dehumidiication and Sleep timer• Output levels of the fans assigned to a zone speciied individually• Integral temperature-humidity sensor to switch the operating mode automatically subject to

the relative humidity indoors• Interface for external input or connection to an existing home automation system• Connections for additional sensors: CO

The Clust-Air module contains the PCB for the zone being controlled. The module is installed in a lush mounted box and connected. After installation, we recommend using a switch style cover or papering over the lush mounted box.

Using the Clust-Air modules it is possible to split the home into separate ventilation zones. Each Clust-Air module is assigned to one ventilation zone. It is installed within its own ventilation zone and can be controlled separately. A Clust-Air module provides control of up to four inVENTer® ventilation units, alignment of one combined temperature-humidity sensor and align-ment of one additional external sensor (digital or analogue).

SYSTEM OVERVIEW


Humidity-temperature sensor FTS31

Fig. 3: Humidity-temperature sensor FTS31

The humidity-temperature sensor is delivered preassembled in a corresponding casing. It is mounted in the room's air low and connected to the Clust-Air module controlling the assi-gned zone. The humidity-temperature sensor integrated into each Clust-Air module continuously captures the relative humidity inside the zone. Depending on the relative humidity, the controller is thus able to switch the dehumidiication mode on and of automatically within speciied limits. This achieves a healthy room climate that meets your needs without the need for manual interventi-on. Observe the correct positioning of the humidity-temperature sensor inside the room's air low. Inadequate circulation of the sensor causes wrong measurement. When installing the hygrost-at, make sure that the ventilation slots are at the top and bottom to ensure optimum airlow to the hygrostat.

SYSTEM OVERVIEW


2.2 Function

Thanks to its unique Clust-Air® technology (multi-zone control), the MZ-One controller is capab-le of controlling up to four zones within a single residential unit. The diferent living areas can each be controlled using the MZ-One controller either by means of a 7-day timer or manually. The controller can be used either as a base module (without connected interface) or with additi-onal sensors connected.

MZ-One controller without connected interface

Heat recovery mode (HR):

The ventilation system works on the regenerator principle. An integral thermal accumulator is charged with heating energy from the warm indoor air as it is discharged outside (extract air). The fan changes its rotational direction every 70 seconds. When the fan changes direction, it releases the stored heating energy to the incoming outdoor air (supply air). This is the standard operating mode during the heating season. It is equally recommended for summer use, since it signiicantly reduces heat input during ventilation.

Ventilation mode (V):

The ventilation device fan operates without changing its rotational direction. This operating mode is recommended for cooling the room on summer nights.

Dehumidiication mode (DH):The dehumidiication mode cannot be selected individually. If the relative humidity in the interior exceeds the preset limit, the MZ-One controller switches all ventilation systems connected to the Clust-Air module in the relevant zone to dehumidiication. High moisture levels in the air are thus removed from the room quickly. The ventilation unit fan operates without changing its rota-tional direction. Once the relative humidity falls below the limit, the MZ-One controller reverts to its previously set operating mode.

Sleep timer (sleep) and OFF:The ventilation device fan is switched of in the mode.

Deining the output level of the controller:On the MZ-One controller, three output levels can be deined and stored for the heat recovery and ventilation modes, and one output level for the dehumidiication mode. These can be altered individually to output levels of between 25 % and 100 %. The new setting takes efect immediately, so it can be changed simply for reasons of acoustic tolerability.

Other settings:

In addition, the brightness and ON-duration of the display unit can be set. This setting similarly takes immediate efect.

SYSTEM OVERVIEW


MZ-One controller with connected interface (advanced features)

The external interface is bifunctional. It can be connected to a loating contact or used as an analogue input for integrating the ventilation system into an existing home automation system. An interface is to be found on each Clust-Air module so that one external interface can be used per Clust-Air module.

Connecting the external interface changes the functionality of your controller as follows:

A. Interface as external contact

Floating ON/OFF switch (N/O)

Select the input ext. switch for the relevant zone under settings in the main menu ( 8.5: Operation ‒ Main menu settings) when connecting an external ON/OFF switch to the Clust-Air module ( 8.12).

The ventilation system can be switched manually to dehumidiication if the external interface is used to connect a loating ON/OFF switch. The dehumidiication mode is deactivated by turning it of at the switch or through the 7-day timer function:

Mode/ function Turning the switch on Turning the switch of

Dehumidiication Switches all ventilation devices on the Clust-Air module to dehumidiication mode.

Switches all ventilation devices on the Clust-Air module back to their previously set operating mode.

External sensors

The sensor used must have a potential-free relay contact (NOC).

The connection of a pressure monitor is necessary in rooms with air-ventilated ireplaces. Please consult a chimney sweep/construction planner about this. If the interface is used for a pressure switch, the air pressure in the interior is measured contin-uously. Once the air pressure exceeds the safety threshold, the sensor reacts and turns of all ventilation devices connected to the programming unit. This function remains active until the air pressure drops back to below the safety limit.

If the external interface is used to connect a CO2 sensor, the CO

2 content in the interior is

measured continuously. A CO2 sensor is optionally available as accessory.

If the external interface is used to connect a VOC sensor, the composition of the air and the resulting air quality are measured continuously.

B. Interface as analogue input

If the interface is used as an analogue input, the ventilation system can be integrated into an existing home automation system. To do so, a predeined voltage level is set in the home automation control unit, depending on the desired function. The control voltage should have a resolution of 10 bits.

TIP: it is not possible to connect a potential-free switch and an analogue input simultaneously on a Clust-Air module. A connected analogue input always has priority over a potential-free switching contact.

When connecting an analogue input to the Clust-Air module, under Settings in the main menu the input analogue must be selected for the relevant zone ( 8.12). Subject to control voltage, the following eight functions are available:

Mode Control voltage

Manual control 0.00 V ≤ U ≤ 0.50 V

Sleep timer 1.00 V ≤ U ≤ 1.50 V

Heat recovery, output level 1 2.00 V ≤ U ≤ 2.50 V

Heat recovery, output level 3 4.00 V ≤ U ≤ 4.50 V

Ventilation, output level 1 6.00 V ≤ U ≤ 6.50 V



C. Disabling interface

If it is not being used, the interface on the Clust-Air module can be disabled under Settings in the main menu ( 8.12).

Terminal assignments

Notice for the Clust-Air module: The terminals are, depending on the terminal, a mixture of screw terminals (fan BUS and external interface) and spring-loaded terminals (control BUS and humidity-temperature sensor). The screw terminals have a connection capacity of up to 1.5 mm². Use braided wires with collared ferrules in screw-terminals. The spring-loaded terminals have a connection capacity of 0.1 to 0.5 mm².

4.4 Zone assignment on the Clust-Air module'e DIP switch

The fans must be allocated to the four diferent zones according to your ventilation concept.

One Clust-Air module controls one speciic zone (all ventilation devices connected to the modu-le). Please observe the following hints:

• Assign a maximum of 4x iV14/iV-Smart ventilation devices per zone (Clust-Air module). or Assign a maximum of 2 iV25/iV-Twin ventilation devices per zone (Clust-Air module). (1 ventilation device = 1 fan BUS)

• Assign ventilation devices working in paired operation to the same zone.

The Clust-Air module must be assigned to its zone via DIP switch located on the module.

Overview

Fig. 10: Position and overview of DIP switch

NOTICEIn case the DIP switch is assigned to the wrong or no zone

the controller cannot gate the ventilation devices connected (no operation of the controller)! ► Assign zones beginning with Zone 1 and serial. ► Observe switch positions. ► Do not assign zones twice.

PREPARATIONS PRIOR TO INSTALLATION


5 Preparations prior to installation

5.1 Installation advices and installation sites

• Carefully read sections Installation and Electrical connections befor installing the controller to avoid installation errors. Installation and electrical connection of the controller must be performed by qualiied personnel.

• Observe the following steps before mounting the controller: Step 1: Disconnect the controller and live parts from power supply. Step 2: Secure the controller against being switched on again. Step 3: Check the disconnected parts for voltage.

• If possible, mount the wall box for the programming unit at a level of approx. 1.50 m over loor. Thus, operation is easier.

• The number of lush mounted boxes/plasterboard boxes required depends on the intended number of zones. One wall opening = for itting the MZ-One programming unit and the irst Clust-Air module Every additional Clust-Air module = one additional box Observe the maximum distances ( 4: Electrical connections).

• Assign each Clust-Air module to its speciic zone correctly. The zone assignment takes place on the DIP switch ( 4.4: Zone assignment).

• NOTICE: Use braided lex to connect the fan BUS. The fan BUS terminal can take wires with a cross-section of up to 1.5 mm². For connecting the fan BUS, we recommend using a LiYY3x0.75 round cable.

• NOTICE: Choose an appropriate installation site for the humidity-temperature sensor in order to assure accurate and representative humidity measurement. Humidity captured at the installation site must represent those in the room. Humidity-temperature sensor must be sited at a point in the room where air circulates.
