SYSTEM OVERVIEW: MZ-HOME CONTROLLER

MZ-Home | Operating instructions
On the controller, three ventilation stages each for heat recovery and ventilation, as well as a
output level for the automatic dehumidification function can be defined and saved. These can be
changed to between 25 % and 100 % of the fan speed of the reversing fan in 5 % steps. The new
setting takes effect immediately, so that adjustments can be made purely by listening to changes
in the sound level.
In addition, the brightness and the display duration of the display unit can be adjusted. This setting
is also effective immediately.
Heat recovery mode
The reversible fans of the ventilation devices
operated in pairs change their direction of rotation
every 70 seconds. The integrated thermal accumu-
lator charges itself with the heat energy from the
room's warm air as it flows to the outside (extract
air). When the fan changes direction, it releases the
stored heat energy into the incoming outdoor air
(supply air).
Select "Heat recovery" as the default operating
mode. During the heating periods, the outdoor
temperature is cooler than the temperature of the
air inside. The outdoor air flowing in is pre-warmed
by being fed over the ceramic thermal accumulator
before making its way indoors. On summer days,
this is also recommended. The higher outdoor
temperature compared to the indoor temperature
means that the supply of heat is significantly re
-
duced during ventilation.
Continuous ventilation mode
In this mode, the reversible fans do not change
their direction of rotation. This means that no heat
recovery takes place.
Select "Continuous ventilation" to cool the room on
summer nights, or to quickly remove stale or humid
indoor air.

MZ-Home controller without connected external interface
If no sensor is connected, the operating modes heat recovery, continuous ventilation and OFF, as
well as the pause function, can be set individually for each zone on the MZ-Home controller by
7-day timer or manually. For automatic humidity monitoring, if connected, the information trans-
mitted to the corresponding Clust-Air module by means of sensors is included in the control of the
ventilation units of a zone.
Automatic humidity monitoring
The dehumidification function is only enabled when
the sensor technology is triggered.
If the relative humidity in the interior exceeds the
predefined limit value (can be changed on the con
-
troller), all ventilation units connected to the Clust-
Air module for the respective zone are switched to
continuous ventilation mode with the air flow volume
defined on the controller for dehumidification.
If the value falls below the limit value, the MZ-Home
switches back to the previously set operating mode
and output level after a 20-minute run-on time.
Pause function
The reversing fan of the ventilation unit is switched
off for a set period of time. The ventilation units do
not work and there is no exchange of air. Select the
"Pause function", for example, before going to bed.
Following the temporary pause, the fans restart in-
dependently at the selected output level and in the
pre-set operating mode. You should therefore leave
the inner cover open.

OFF mode
The reversing fan of the ventilation unit is perma-
nently switched off. The ventilation units do not
work and there is no exchange of air.
