About OneZone VRF

OneZone VRFOneZone VRF is an integrated zoning system specially designed for Inverter systems, VRF multi and monosplit solutions. The key element behind this integrated zoning solution is the communication gateway. This device manages the communication between the zoning system and the Indoor Unit, increasing both comfort and energy efficiency.

VRF Inverter technology offers high efficiency and increased controllability, by regulating the amount of refrigerant flowing to each Indoor Unit. By integrating this advanced technology with the OneZone VRF system, it is possible to simplify it and make it less expensive. The result will be a better installation.

OneZone VRF is the only zoning system that works with Inverter (VRF and split units). Our communication gateway is specifically designed and validated for the main HVAC brands. It controls 3 main parameters according to the status of each zone: Operation mode, set-point temperature and fan speed, depending on the installation’s demand.

Inverter technology has arrived to stay and there is a way to improve it. Combining OneZone VRF with Inverter (VRF and split units) represents a huge opportunity to decrease the initial and maintenance costs. And make a very efficient technology, even more efficient.

The OneZone VRF configuration per indoor unit (controlling up to 10 zones) includes the following items:

  • OneZone VRF Main Controller with integrated Communication Gateway
  • One Wired Main Thermostat Blueface.
  • A zone Thermostat for each controlled zone (except for the principal zone which has a Blueface). These zone Controllers can be wired or wireless
  • As many Intelligent round Motorized Dampers as needed. Wired or wireless depending on the user needs. These dampers come in 6’’, 8’’ and 10’’




Our system could be integrated into any BMS. We have a direct port RS485 for ModBus, and a BACnet plug&play gateway. With these options, OneZone VRF can integrate into any BMS for residential and commercial applications.
