SystemAir MZ3-Touch - Controller/Positioner For Comfort Ventilation Manual

Functions

Positioner and controller for comfort ventilation with touch panel

• Design according to Feller EDIZIOdue^®
• Manual operation with up to 4 steps
• AUTO operation: The controller activates the ventilation based on controls curve.
• Automatic reset of the Party air level
• One 0...10 VDC controls output to control the ventilation system
• One 0...10 VDC input to measure CO2 or other sensors

Applications

Control of ventilation systems for comfort applications. For example for well insulated residential areas which are required to be ventilated

General description

The MZ3-Touch is a microprocessor controlled precision positioner and controller with touch panel.

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

Mounting location

On an easy accessible interior wall, approx. 1.5 m (4.5') above the floor. The MZ3-Touch is so designed that it can be incorporated into a commercially available flush box (Feller EDIZIOdue^® frame and mounting plate are included).

Description:

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)

Parameter copy

It is possible to copy settings to an accessory (AECPM2) 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 OP05 to 1.

AEC-PM2 "Data" LED is ON for 5 seconds after successful parameter copy and OP05 is set to 0. If the parameter copy failed the LED blinks for 5 seconds and OP05 is set to 7.

Copy parameter from AEC-PM2 to MZ3 simply by pressing the "Copy" button on the AEC-PM2. AECPM2 "Data" LED is ON for 5 seconds after successful parameter copy. If the parameter copy failed the LED blinks for 5 seconds.

Display and 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

If a sensor signal is detected at the input, the automatic operation of the device is enabled.
The following operation modes will be activated through repeated pressing of the step button:

Minimum = 1/5 Volumenstrom*
Normal = 2/5 Volumenstrom*
Maximum = 3/5 Volumenstrom*
Party = 5/5 Volumenstrom* for 2h, after which it will automatically switch to the 3/5 flow.
*Equal to the difference of Vmax to Vmax

Auto mode
In automatic mode, the volume flow is regulated on the basis of CO2 or air quality sensors. The operating modes are activated only after 10 seconds. This prevents unnecessary switching when setting the device.

AUTO operation

If a sensor signal is detected at the input, the automatic operation of the device is enabled. IP08 defines a time delay after which the unit returns to automatic operation once placed into manual.

Level Mode (IP00=ON)

The ventilation level is then activated based on the sensor signal and the limits defined under IP04 – IP06 Setting a level limit of IP05 – IP06 to 0, deactivates this level for automatic mode. The sensor signal will then not be able to activate this particular level.

Continuous Mode (IP00=OFF)

The ventilation is controlled gradually by the sensor signal. Instead of level steps, the output voltage is adjusted continuously. The sensor minimum and sensor maximum of the linear range can be set with IP04 and IP06. The output voltage then behaves linearly between OP00 and OP03.
