LX Series Unit Ventilator Controller User's Guide28
The UVC uses a half-wave power supply. Any other half-wave power supply that
connects with the controller through the outputs or inputs must be in phase with the
power supply of the controller. Do not share grounds between a full-wave and a
half-wave power supply.
You can reverse each of the digital output’s scales by using the Unit Ventilation
configuration wizard. Normally, ON is a 100% output; when the output is reversed,
ON is a 0% output.
You can override all digital outputs to a previously set value using the UVC object
override command. The override values are set during the configuration process.
The configuration wizard provides a menu for issuing object commands, including
the override command. See the Object Manage section for more information.
