Ranco ETC-211100-000 Temperature Control

The Ranco ETC-211100-000 is an industrial-grade dual stage electronic temperature control engineered for high-precision HVACR applications. Operating on 120/240V AC input, this microprocessor-based controller offers a wide setpoint range from -30°F to 220°F. Designed for versatility, the ETC-211100-000 features two independent SPDT relay outputs and a specialized 0-10V analog output for modulating equipment or integrating with building automation systems. The 1°F resolution and adjustable differential (1°F to 30°F) provide tight control over compressor cycling or heating stages, minimizing equipment wear. The NEMA 1 rated enclosure protects the digital thermistor control logic, while the backlit LCD provides clear visibility of the ambient temperature sensor readings and programming parameters. Contractors rely on this unit for commercial refrigeration control, chiller sequencing, and space heating due to its field-proven reliability and easy DIN rail or surface mounting options.

• Dual Stage Control: Independent adjustment of two stages for precise heating, cooling, or combination sequencing.
• Analog Integration: Built-in 0-10V signal output for interfacing with variable speed drives or modulating actuators.
• Non-Volatile Memory: Maintains all programmed parameters during power loss, eliminating the need for field reprogramming calls.
• Wide Diagnostics: Provides ongoing status of thermistor sensor inputs with failure mode default settings to protect system integrity.
• Flexible Differential: Wide adjustment range prevents short-cycling in high-load commercial environments.

Can the Ranco ETC-211100-000 operate stages in different modes?
Yes, this controller allows each stage to be independently set for either heating or cooling mode, making it ideal for changeover applications or humidity control via reheating.

What type of sensor is compatible with this unit?
The unit utilizes a standard 1,000 ohm thermistor sensor. Always ensure the Ranco temperature probe is mounted away from localized heat sources for accurate HVAC temperature regulation.

Is the 0-10V output configurable?
The analog output is designed to track the primary sensor input, providing a proportional signal used frequently in commercial HVAC sequence of operations and modulating damper control.
