Zennio simplifies KNX fan-coil control

The new Zennio MAXinBOX FC 0-10V replaces the previous FAN and VALVE versions and provides flexible 0-10 VDC control for KNX fan-coil systems.

With the MAXinBOX FC 0-10V, Zennio introduces a flexible solution for KNX fan-coil control. The new controller is designed for 2- and 4-pipe fan-coil units and is available under reference ZCLFC010.

As the official Zennio distributor, we offer the new MAXinBOX FC 0-10V for KNX projects that require a compact solution for fan control, valve control and additional automation functions.

The MAXinBOX FC 0-10V replaces the previous MAXinBOX FC 0-10V FAN and MAXinBOX FC 0-10V VALVE models. This simplifies product selection for planning, purchasing and stock management, while maintaining flexibility in fan-coil control.

Flexible control of fans and valves

The controller features 2 individual 0-10 VDC outputs, 4 potential-free relay outputs and 4 analogue/digital inputs. Depending on the application, the 0-10 VDC outputs can be used for fan or valve control. The relay outputs can be assigned to fan speeds, on/off valves or other loads.

Outputs not required for the fan-coil function remain available for other control tasks within the KNX installation. This makes the device particularly suitable for projects that require compact dimensions, flexible parameterisation and versatile output functions.

  • 2 x 0-10 VDC outputs for fan or valve control
  • 4 potential-free relay outputs
  • 4 analogue/digital inputs for sensors, push buttons, temperature probes or motion sensors
  • 2 integrated thermostats
  • 10 logic functions
  • Support for 4-way and 6-way valves with 0-10 V control
  • Manual output operation with LED status indication
  • Compatible with KNX Data Secure

One device for different fan-coil applications

MAXinBOX FC 0-10V can be used with 2- or 4-pipe fan-coil units. Possible applications include two fan-coil units with 0-10 V fan speed control, or one fan-coil unit with 0-10 V valve control.

Support for 4-way and 6-way valves further extends the range of applications. Combined with integrated thermostats and 10 logic functions, the controller provides a powerful basis for modern HVAC automation in KNX projects.

Compact installation in distribution boards

The device is mounted on a DIN rail and occupies 4 modules. It is supplied directly via the KNX bus and does not require an external power supply. The operating temperature range is 0 to +55 °C, the degree of protection is IP20 and the dimensions are 67 x 90 x 70 mm.

With the Zennio MAXinBOX FC 0-10V, system integrators, planners and specialist partners have a versatile KNX solution for fan-coil systems in commercial buildings, hotels, residential buildings and demanding HVAC projects. The new reference simplifies product selection while providing greater flexibility during implementation.
