The IP address of each unit needs to be set prior to integration into the control network.

This article explains the IP address setting to enable communication between controllers and units under three scenarios. 


*Not sure about where and how to change the IP address? Please see article: Step-by-step Guide to Set IP Address on Controller/Unit




Scenario 1: End-user provides IP address for controllers and units


  • If the end-user provides IP settings for controllers and each HVAC, change the values on the units accordingly. 
  • Format is Y.Z.W.X


Scenario 2: End-user provides IP address for the controller only


  • If the end-user provides IP setting only for the controller to enable remote monitoring, set the IP address to Y.Z.W.X accordingly on the controller.
  • On each HVAC unit, set the IP address to Y.Z.11.X, where Y and Z are the same as that of the controller and X, is the unit number. For example, if the controller IP is set to 192.168.20.45, set unit #1 to 192.168.11.1 and unit #2 to 192.168.11.2
  • Mask: Always use 255.255.0.0

Scenario 3: End-user does not provide the IP address for the site


  • If the end-user does not privide any IP address for the site, verify the IP address on the controller to be 192.168.11.17 or 172.168.11.17 by default. 
  • On each HVAC unit, set the IP address to 192 (or172).168.11.X. X is the unit number. For example, if the controler IP address is 192.168.11.17, unit #1 IP address should be 192.168.11.1. Unit #2 IP address should be 192.168.11.2. 
  • Mask: always use 255.255.0.0
  • Leave other fields blank
