Ontrol ORION & Belimo Compact --- a match made in (controls) heaven 

Ontrol's ORION provides a unique, one-of-a-kind solution for VAV (Variable Air Volume) controls when coupled with standard Belimo Compact devices.

  • Belimo LMV and NMV compact actuators are perhaps the most widely used VAV flow control devices in Europe. They represent the first choice for OEMs (VAV Box manufacturers) to deliver a controls-vendor agnostic solution.
  • Ontrol ORION touch-screen controller boasts a dedicated direct comms port to digitally integrate standard Belimo Compact VAV devices. 

This unique combination makes possible an advanced solution with dramatically reduced wiring.

THE SOLUTION
Belimo Compact

With integrated ΔP sensor and internal air flow calculation and control algorithms, Belimo LMV and NMV compact actuators provide a compact easy-to-mount solution. This is ideal in terms of project management, because actuator and flow-controller as a single device can be supplied already mounted and calibrated by the VAV box manufacturer (OEM) in a truly controls-vendor agnostic fashion, reducing field labor and potential problems dramatically.

Ontrol ORION

The ORION is an extremely versatile device designed to provide intuitive user interaction and real-time control. Built-in temperature and humidity sensors are standard, with CO2 sensing as an option. The user interface is fully customizable and complex control algorithms can be easily programmed into the device, allowing autonomous real-time control of one or more VAV boxes. And most importantly, the ORION has a direct MP-Bus protocol comms connection to Belimo devices.

An Elegant Combination

Ontrol ORION's integrated MP-Bus communication port allows control of standard Belimo Compact devices over two-wires without requiring any physical inputs or outputs. This reduces wiring and connections dramatically. All data, including temperature, humidity, Co2, air flow, damper position etc are communicated digitally between intelligent devices.

Look Ma, no I/O wires!

ORION's integrated MP-Bus communication port allows control of standard Belimo Compact devices over two-wires without requiring any physical inputs or outputs. This reduces wiring and connections dramatically.

  • The differential pressure sensor for air flow calculation is an integral part of the Belimo Compact actuator.
  • Ambient temperature and relative humidity sensors are standard on the wall-mounted ORION.
  • Control and feedback values for both damper position and airflow are all transmitted via the MP-Bus connection.

Flexible system extension

Going beyond the basics, the solution is open to extending capabilities in endless ways. Some basic options:

  • The ORION can optionally be ordered with an on-board CO2 sensor.
  • The analog inputs (Y signal) on the Belimo Compact actuators are no longer necessary in this configuration. They can easily be repurposed to connect additional sensors (e.g. occupancy sensor, discharge temp sensor...)
  • Where additional outputs are required, standard Modbus input/output modules can be connected to ORION's auxiliary RS485 port.

Systems Integration

The ORION supports simultaneous communication on multiple ports/protocols.

  • Control functions execute locally via MP-Bus comms without any reliance on supervisory controllers or external wiring.
  • Systems integration is enabled using Modbus or BACnet protocols, allowing a supervisory system to have remote access to all operational data.
  • Further integration of downstream I/O devices is possible thanks to an additional, completely independent Modbus port - standard on all versions.
