The Multispan UTC-214 is a temperature controller designed for precise temperature management in various industrial applications. It offers a range of control methods and input types, making it a versatile solution for heating and cooling processes.

Function Description:

The UTC-214 primarily functions as a temperature controller, capable of maintaining a desired temperature setpoint through various control actions. It supports PID control with auto-tuning, time proportional (TP) control, and ON-OFF control for both heating and cooling applications. The device accepts multiple input types, including J, K, PT-100, and PT.1 thermocouples and RTDs, allowing it to interface with a wide array of temperature sensors. It features a clear 4-digit, 7-segment red LED display for process value and setpoint indication, along with status LEDs for control output (OUT) and auto-tune (AT) indication. The controller provides a relay output (1C/O) for switching external loads and an SSR drive output for solid-state relay control.

Usage Features:

• User-Friendly Interface: The controller features a simple 4-button interface (SET, INC, DEC, ENT) for easy parameter setting and navigation.
• Auto-Tuning Function: The auto-tuning feature automatically calculates and sets the optimal Proportional band (Pb), Integral time (It), Derivative time (dt), and cycle time based on process characteristics. This simplifies setup and ensures efficient control. The tuning LED illuminates during auto-tuning, and the process restarts if power is interrupted before completion.
• Password Protection: Access to parameter settings can be protected by a password (default 73 for basic configuration, 37 for control parameters, and 50 for setpoint setting) to prevent unauthorized changes.
• Error Display: The device displays error codes (e.g., "OPEN" for sensor not connected/over range/break, "SrE" for sensor connection reversed) to assist in troubleshooting.
