VRV Interface Module


Daikin and Honeywell® collaborated in developing a solution that couples INNCOM’s integrated guest room automation system with Daikin’s industry leading VRV solution. The developed INNCOM interface module (part number: DD15) seamlessly integrates the VRV indoor unit with the INNCOM thermostat and INNCOM Energy Management System (EMS). This module provides direct digital control of the VRV system from Honeywell’sINNCOM E7, E527 and E528 thermostats. The INNCOMenergy management system can control and monitor each VRV indoor unit through the INNCOM thermostats and the DD15 Interface without the loss of Proportional–Integral–Derivative (PID) control in the VRV system.



  • Easy installation with plug-and-play connections
  • Synchronizes room temperature between INNCOM and VRV indoor unit
  • Full modulation of the Daikin VRV indoor unit electronic expansion valve (EEV)
  • Compatible with INNCOM EMS
    • Wireless mesh network
    • Full compatibility with INNCOM EMS and devices
    • INNCOM E7 thermostat allows for compatibility with Amazon Alexa
