CVRFH: VRF Host Module

CVRFH: VRF Host Module

iZone VRF is ONLY compatible with both ME VRF and Daikin VRV at the moment.

 

The iZone VRF AC Host Module (CVRFH) will eliminate the need for an iZone CPU module and smart hub for every indoor unit, which results in a cost-effective climate control solution. Install a single iZone 8-zone CPU module on one of the indoor units, then install a VRF AC Host Module and AC unit module on every subsequent indoor unit and connect them together with a CAT5 cable.

Features

  • Pin indoor AC fan coil units as a device/zone on the Nova home screen

  • Customise the home screen to easily control every indoor unit and zone

  • Add schedules/scenes to suit your needs

  • Control system remotely from your mobile phone

  • Connect up to 16x indoor units to a single VRV outdoor system

  • Connect up to 5x outdoor systems to a single Nova controller

  • Connect up to 8x Nova controllers on the same network with no additional hardware modules required

  • Step-by-step onscreen installation wizard to set up and configure system
