Note: Humidification is possible only when you have extended the controller’s features using LC-IOM3711-0.
To check if a humidity sensor is installed, navigate to . If a humidity sensor is set to something other than Not Installed, and the Humidity Enable parameter in the section is set to Enable, the option for humidification is present. When humidification is present, the unit modulates the humidity output to maintain a humidity setpoint. A humidifier binary output is also energized when a required humidification is present. You must install a humidity high limit transmitter, for example, the P/N HL-67N5-8N00P, in the duct to limit the maximum humidity level discharged by the humidifier.
