SYSTEM OVERVIEW: MZ-HOME CONTROLLER

MZ-Home | Operating instructions
If the external interface on the Clust-Air module of the controller is assigned, the range of
functions changes as follows for the corresponding zones:
A: Demand-controlled ventilation via sensors, or
B: Integration of a safety device (e.g. pressure monitor) with simultaneous operation of the
ventilation devices with fireplaces, or
C: Integration of the ventilation system into an existing building management system.
In all configurations, all of the controller's functions are available without a connected external
interface.
A: Demand-controlled ventilation via sensors
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, further demand-controlled ventilation is
possible.

Change all ventilation units
on the
Clust-Air module
to
the originally set operating
mode.
If the predefined limit value (can be changed on the corresponding sensor) is exceeded, the
sensor transmits a control signal to the respective Clust-Air module. The controller then switches
all ventilation devices connected to the Clust-Air module to ventilation mode.
The function remains active until the corresponding parameter falls below the pre-set limit again.
Then all ventilation devices connected to the Clust-Air module switch to the originally set operat-
ing mode and output level.
– If a CO
2
sensor is connected, the CO
2
content in the interior is continuously measured. A
CO
2
sensor can be ordered as an optional accessory.
– If a VOC sensor
1)
is connected, the composition of the air in the interior and the resulting air
quality are measured continuously.
When connecting an external sensor to the Clust-Air module, the
Ext. Switch
input must be
