MZ-Home | Installation instructions
1.2 Safety instructions
The installation instructions are part of your MZ-Home controller and must be available at all times
(see www.inventer.eu/downloads). When handing the system to a third party, the information
regarding access to the installation instructions must be handed over also.
Before performing any work on the equipment/system, read the installation instructions carefully
and observe all notices that refer to the installation process in this section.
Also note the safety instructions that precede the described handling instructions. Non-obser-
vance of safety instructions could result in injury and/or property damage.
Intended use
The MZ-Home controller (also referred to in the text below as "controller", "MZ-Home controller")
is a component of a decentralised iV ventilation system with heat recovery (product series
used for controlling the corresponding ventilation units of the ventilation system from inVENTer
GmbH.
• The MZ-Home controller for controlling the inVENTer ventilation units with heat recovery
integrated into the system.
• The sensor technology paired with the controller (HYG18 humidistat, HYG12 humidistat, CS1
pressure monitor) for the delivery of temperature, humidity and COvalues to the MZ-Home
controller, which in turn uses these values to control the inVENTer ventilation units with heat
recovery.
Requirements for intended use
• Always observe the relevant standards, regulations and guidelines when installing the equip-
accident prevention regulations of the employers' liability insurance association.
• Use the units integrated into the ventilation system only in accordance with the applications
that are described in this documentation and only in conjunction with the components that are
recommended, approved and named by inVENTer GmbH in this documentation.
• Before starting work, you should have a project plan showing the number of ventilation units,
the location of the ventilation units, the ventilation principle (cross ventilation, single room venti-
lation, extract ventilation) and the associated controllers. The exact positioning of the individual
units and control units must be checked at the installation site and, if necessary, adapted to the
local conditions with the involvement of the responsible planner or user.
• Your ventilation system is exclusively designed for use in ambient temperatures between
-20 and 50 °C.
• Trouble-free and safe operation of the equipment/system depends upon proper transportation,
proper storage and installation as well as careful operation and maintenance.
• These installation instructions are only valid in conjunction with the installation and operating
instructions of the corresponding ventilation unit with heat recovery and supplement these.

• NOTICE: Ensure adequate contact between the wires when connecting the MZ-Home
controller.
• NOTICE: Laying cables whose sheathing is not resistant to plastering under plaster leads to
• NOTICE: The use of too small a cable cross-section leads to too great a voltage drop and/or

2 System overview: MZ-Home controller
The MZ-Home controller is an electronic programming unit for controlling inVENTer®ventilation
units with heat recovery.
It features Clust-Air technology (multi-zone control), easy installation, touch operation and a wide
variety of possible uses.
The MZ-Home consists of an operating unit and up to four Clust-Air modules. Each Clust-Air
module controls the ventilation units in one zone within the accommodation unit. This allows the
one accommodation unit.
For each zone, the operating mode and ventilation level can be set manually or via a weekly timer.
The MZ-Home allows the control of the following maximum number of ventilation units:

2.1 Construction
The MZ-Home controller consists of a programming unit and at least one up to a maximum of
4 Clust-Air module(s).
The operating unit is mounted directly on the interior wall by means of a mounting box. It serves
as an operating and display interface for the user.
In addition to the operating unit, one Clust-Air module is required per ventilation area (zone). The
Clust-Air module contains the electronics for the zone to be controlled and is mounted in it. It is
The humidity and temperature sensor is part of the Clust-Air module. It is supplied pre-assembled

2.2 Function
The MZ-Home controller is a control unit for decentralised ventilation units with heat recovery from
inVENTer GmbH.
Thanks to its unique Clust-Air technology (zone control), the MZ-Home controller is able to control
up to four areas (zones) within an accommodation unit separately from each other. For each
zone, the operating mode and output level can be set manually or via a weekly timer. Due to the
automatic humidity monitoring, the controller also has demand-controlled ventilation if the interior
humidity values are too high.
If connected, the information transmitted to the corresponding Clust-Air module by means of
external sensors, e.g. COsensor, is also included in the control of the ventilation units in a zone.

pause function, can be set individually for each zone on the MZ-Home controller by weekly timer
or manually.
Humidity monitoring cannot be selected manually, it is activated automatically by the sensor

previously set operating mode and ventilation level after a 20-minute run-on time.
For the ventilation units, three ventilation stages each for heat recovery and ventilation, as well as
changes in the sound level.
In addition, the brightness and the display duration of the display unit can be adjusted. This setting

the controller is extended as follows:
The external interface is a bi-functional interface. It enables
A: The connection of a sensor with potential-free switching contact (NO contact), or
the integration of a safety device (potential-free switching contact, e.g. pressure sensor

existing building management system.
There is an external interface on each Clust-Air module.

If sensors are connected to the MZ-Home controller's Clust-Air module, the range of functions is
extended. In addition to automatic humidity monitoring, extended demand-controlled ventilation or
the integration of a safety device is possible.
When connecting external sensors to the Clust-Air module, the Ext. switch input (NO, sensor
system without safety device) or CHIMNEY SWITCH (NO or NC, safety device) can be selected
for the respective zone (MZ-Home operating instructions).
The sensor used must have a potential-free relay contact as its output.

(maximum cable lengths) between the individual modules.
• The connection terminals, depending on the connection, are either a screw terminal (fan BUS
and external interface) or spring-loaded terminal (control BUS and humidity and temperature
sensor).
• The screw terminals have a connection capacity of up to 1.5 mm². Use rigid wires or wires with
wire ferrules in screw terminals.
The spring-loaded terminals have a connection capacity of 0.1 to 0.5 mm². They are suitable for
rigid wires.
• If wire ferrules are used, they must increase the cross-section. Their material thickness is not
included.
• Terminate the last Clust-Air module connected with a terminating resistor.

3.4 Zone assignment on the DIP switch of the Clust-Air module
The existing fans must be divided into zones, according to the ventilation concept.
A Clust-Air module is used to control all ventilation units connected to the module. Observe the
following notes when dividing:
• At least 1 (max. 4) Clust-Air module(s) is required,
• Connect a maximum of 4 ventilation units with Xenion reversing fan per Clust-Air module,
or
Per Clust-Air module connect a maximum of 2 ventilation units with Xenion EFP reversing fan
or Mini-Xenion,
• Assign ventilation units operated in pairs to the same zone,
• For assignment/addressing of the zones, start with zone 1 and assign consecutively;
the modules themselves do not necessarily have to be switched in sequence:
The ventilation zone is assigned at the DIP switch on the Clust-Air module.
