Display & Operation
ON/OFF operation
The device is activated by pressing the ON/OFF button.
Depending on the position of JP1, the minimum air volume
remains active even during OFF mode. In OFF mode, the
operating mode symbol lights up with reduced intensity
Manual operation
The following operation modes will be activated through
repeated pressing of the Level button:
Level 0 = Minimum air volume
Level 1
Level 2
Level 3 = Maximum air volume
Auto operation
The operating modes are activated after 2 seconds. This prevents unnecessary switching when setting the device. The
Level-indication and buttons light up in green or blue depending on the type of device.
The device is equipped with proximity detection. When approaching a distance of approx. 10 cm, the luminosity of the
LED increases. After 30 seconds without interaction, the LEDs dim down again and thus save energy.
AUTO operation
The automatic operation of the device is enabled once a sensor signal is detected at the input. During AUTO operation the
levels are switched by a control signal. The switching levels are defined under IP04 – IP06.
The hysteresis defined with IP07 prevents rapid switching of levels in auto mode.
Function: A level activates once the input signal exceeds the activation limit (IP04-IP06). It deactivates once the input
signal drops below the activation limit minus the hysteresis. For example, with a hysteresis of 10% and an activation limit
of 40%, the level activates with a 40% input signal and switches down to the next lower level with a 30% input signal.
Automatic switching for certain levels may be disabled by setting an activation limit of 0. The sensor signal will then not
be able to activate this particular level. This may proof useful for the highest level. (boost mode)
IP08 defines a reset time after which the unit returns to automatic operation once placed into manual.
Setting this time to 0, prevents the automatic reset.
Software configuration
The MZ3-FA-V11 is designed to work for most comfort ventilation applications. It is however possible to fine tune it to fit
perfect into the application at hand. The parameters can be changed during operation through an operation unit called
OPA-S.
The operating unit OPA-S must be connected for the adjustment of the parameters with the MZ3-FA-V11. This
connection must not be disconnected earlier than five seconds after the last keystroke.

Parameter
Description
IP00
Input signal show percent
IP01
Samples taken for averaging input signal
IP02
Offset of input signal (Uout = Uset+Offset)
IP03
Input signal type OFF = 0-10V, ON = 2-10V
IP04
Activation limit for level 1 in auto mode
IP05
Activation limit for level 2 in auto mode.
Note: Setting this Level to 0, disables it for automatic operation.
IP06
Activation limit for level 3 in auto mode
Note: Setting this Level to 0, disables it for automatic operation.

Parameter
Description
OP00
Output level 0
OP01
Output level 1, Setting a level to 0 disables it
OP02
Output level 2, Setting a level to 0 disables it
OP03
Output level 3, Setting a level to 0 disables it
OP04
Automatic reset time of the highest level to the level defined in
OP05. The reset is deactivated with setting = 0
OP05

once the reset time defined in OP04 has expired.
