Does the product come with a guarantee?

OneZone VRF comes with a 2 year guarantee against defects.

Are OneZone VRF controllers wired?

OneZone VRF has the option of wireless and wired zone thermostats. The only thermostat that needs to be wired is the main controller Blueface.

What items do I need to add OneZone VRF to my installation?

You need a Main Board with a Communication Gateway, a Blueface master Thermostat, a wired or wireless damper for each zone, and a Tacto Zone thermostat per zone. Depending on the size of the zone it can have more than one damper. One Tacto thermostat can control more than one damper.

Why is the installation and maintenance costs budget going to decrease if I add VRF to my Inverter (VRF and Split) installation?

When you have an Inverter installation you have mini splits or cassettes in each zone. Therefore, each zone needs refrigerant piping, electric points, water drainage, filters, etc. If we replace these cassettes or mini splits by our zone dampers, we need less material and the installation is faster. Plus, our dampers need less maintenance than these complex devices.

Can I connect OneZone VRF with another Building Automation System (BMS) different from ModBus or BACnet, such as Crestron or LonWorks?

Yes, our ModBus port can be connected to Crestron, KNX, LonWorks, etc.

What happens if I close all of the dampers?

Since there is no zone calling demand, the fan will be stopped.

What’s the difference with VAV?

VAV boxes are more difficult to install, to commission and to maintain. OneZone VRF with its modulating dampers and controlling the fan speed provides the needed airflow continuously.

Are the dampers on/off or modulating?

OneZone VRF motorized dampers can be configured as modulating. They will open or close in 4 steps.

Do I need a bypass damper?

No, we have control of the Indoor Unit through the Communication Gateway. Depending on the real demand, we can vary the fan speed and even turn the unit off.

How does OneZone VRF make the VRF System more efficient?

Since we have control of the Indoor Unit through the Communication Gateway, we have a better understanding of each zone demand. The user can chose how proficient is the performance of the unit by means of efficiency algorithms.
