General description
The MZ3-FA-V11 is a microprocessor-controlled precision positioner and controller with touch panel. Through user and
engineering parameters the positioner may be configured to work for most of the standard ventilation applications. The
device is pre-configured according to this documentation. Settings such as switching levels of the control curve and
ventilation strengths for each Level may be adjusted. The configuration may be performed using the programming device
called OPA-S. This device may be used as well to visualize measuring values.

Interface to the ventilation system
The positioner works with all ventilation systems that are designed with a 0...10 VDC or 2...10 VDC input signal.
Selection of transmitters
The positioner works with all sensors that provide an output signal of 0...10 VDC or 2...10 VDC. The measuring range
needs to be observed.
For example: CO2 0...2000 ppm = 0...10 VDC or 2...10 VDC.

Installation and safety advice
This device is intended to be used as positioner for comfort ventilation systems. Where a device failure endangers human
life and/or property, it is the responsibility of the client to add additional safety devices to prevent or detect a system
failure caused by such a device failure.
The device contains electronic components and must not be disposed of with household waste.
Setting of the device to keep fan running in minimal volume in OFF mode
If JP1 in position 1-2, the output is off in OFF mode. Ventilation switches off.
If JP1 in position 2-3 or removed, the output stays in OFF mode in Level 0 (minimum air volume)

New with V2.0: Parameter copy
It is now possible to copy settings to an accessory (AEC-PM2) and to copy them back to other MZ3. For this, remove the
front panel of the MZ3, insert AEC-PM2 in the designated plug. Connect OPA-S and copy parameter from MZ3 to AEC-PM2
by setting OP06 to 1.
AEC-PM2 “Data” LED is ON for 5 seconds after successful parameter copy and OP06 is set to 0. If the parameter copy
failed the LED blinks for 5 seconds and OP06 is set to 7.
Copy parameter from AEC-PM2 to MZ3 simply by pressing the “Copy” button on the AEC-PM2. AEC-PM2 “Data” LED is ON
for 5 seconds after successful parameter copy. If the parameter copy failed the LED blinks for 5 seconds.

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.
