Description
The Siemens DDC 540-110N Unit Conditioner Controller TEC is a direct digital regulator for controlling the operation of fan coil units and pressure-dependent terminal parts. It reads data from the sensors and regulates heating, cooling and fan operations to ensure the desired temperatures are attained. This controller is typically used in commercial HVAC systems, and may be used as a standalone controller or as a part of a building automation network. It is designed to be the system’s controller to equipment operation, monitor conditions and temperature as programmed by control logic.
