General description
The MZ3-FU-V01 is a microprocessor-controlled precision level switch with touch
panel. Through parameters the level switch may be configured. Settings such as
switching levels for each step may be adjusted. The level switch is configuration with
a programming device called OPA-S. Configuration can as well be updated using a
remote memory device called AEC-PM2.
Safety

NOTE: For parameter programming, the OPA-S programming and display unit must be plugged in at the connector
under the front panel or on the back of the MZ3.

Display and Operation
Manual operation
The following operation modes will be activated through repeated pressing of the
level button:
-Level 0 = MIN = Minimum
-Level 1 = MID = Medium
-Level 2 = MAX = Maximum
The active level is activated after 3 seconds. This prevents unnecessary switching
when setting the device. The level-indication and buttons light up in blue.
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.

Setting the parameters
The MZ3 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.
Carefully lift the front panel of the MZ3 and pull it away to the front. Plug the
connecting cable of the OPA-S operating unit into the rear part of the MZ3.
Important
The MZ3 does not accept the new settings until the OPA-S parameter menu is exited. The connection must not be
disconnected earlier than five seconds after the last keystroke!
Copy parameters
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.
Copy parameters from MZ3 to AEC-PM2
Connect OPA-S and copy parameters from MZ3 to AEC-PM2 by setting OP06 to 1. The
"Data" LED of the AEC-PM2 lights up for 5 seconds after successful parameter copying
and OP06 is set to 0. If parameter copying has failed, the LED flashes for 5 seconds and
OP06 is set to 7.
Copy parameters from AEC-PM2 to MZ3
Copy the parameters from AEC-PM2 to MZ3 simply by pressing the "Copy" button on the
AEC-PM2. The "Data" LED on the AEC-PM2 will light for 5 seconds after the parameters
have been successfully copied. If the parameter copy failed, the LED will blink for 5
seconds.
