Job _________________________
mZone is a fully programmable zone controller available in two different sizes: 8 and 12 zones. It is assembled
with industrial grade components for commercial and residential high-end applications. It connects with mBox via
Ethernet or, alternatively, via serial bus (RS485 slave) and integrates with the Messana climate control platform
developed with more then 20 years of experience in radiant cooling and heating technology.

  • Page 5 Inputs / Outputs contacts ZONE THERMAL ACTUATORS (24VDC) (mZone8DO1-DO8 and mZone12DO1-DO12) mZone 8 features eight digital outputs (DO1-DO8) and mZone 12 twelve digital outputs (DO1-DO12), dedicated to the activation of zone thermal actuators or zone valves. mZone 12 mZone 8 Each digital outputs is a 24VDC normally open contact with max 5Amps.
  • Page 6 0-10V or 2-10V programmable opto-insulated analog outputs for controlling motorized mixing valves, servo motors, actuators, fan-coils, and other analog devices. Can also be reprogrammed as 4-20mA. AO1 MIX (available on both mZone 8 and mZone 12) is typically used to control a motorized proportional mix valve to adjust the radiant fluid temperature.

    ON and OFF. DI AUX mZone 8 do not offer any digital input pre-wired on the terminal blocks on the DIN bar. Additional 11 Digital Inputs (DI1-DI11) are available directly on the embedded Emerson I/O controller and need to be wired directly on the push-in connectors located on the controller.
  • Page 8 The voltage supplied by the relay DO8 (PWR) is 110VAC or 220VAC, depending on the mZone AC power, and is protected by the same fuse of the mZone 8. Any high voltage device connected to DO8 (PWR) will be powered by the same mZone AC power supply and will be protected by the same fuse.
