Description
The Macon Model ZMC-DDC Proportional is a thermoelectric actuator for the discrete control of heating and cooling systems in direct proportion to the applied control voltage. The control of the actuators is performed by a 0-10 V DC signal via a central DDC system or by a room thermostat. Principal area of application is the building management systems range.

Features:
  • Simple plug-in installation
  • Travel path variants 4.0 mm / 5.0 mm (further variants on request)
  • Power consumption of only 1 watt
  • Control by a 0-10 V DC signal
  • 360° installation position
  • Short response times, resulting in improved control response
  • Closing point verification and possible adaptation during operation
  • All-round function display
  • Complete compatibility to the valve adapter system
  • Noiseless and maintenance-free
  • High functional safety and long expected service life
  • Patented 100% protection in case of leaky valves
  • “First open” function
  • Adaptation check on the valve
  • Plug-in connecting cable
  • Alignment aid on the valve
  • Compact size, small dimensions

The actuator mechanism of the Macon ZMC-DDC uses a PTC resistor-heated elastic element and a compression spring. The elastic element is heated by applying the operating voltage and moves the integrated plunger. The force generated by this movement is transferred to the plunger, thus opening or closing the valve.
