Ranco ETC-112100-000 Temperature Control

The Ranco ETC-112100-000 is an industrial-grade single stage electronic temperature control engineered for precision in demanding HVACR environments. This 24V digital thermostat features a versatile SPDT switch and a wide operating range of -30°F to 220°F, making it a reliable choice for commercial refrigeration, walk-in coolers, and space heating applications. The integrated 0-10V analog output provides a linear representation of sensed data, allowing for seamless integration with Building Automation Systems (BAS) or remote monitoring equipment. Built with a NEMA 1 enclosure, the unit includes a high-visibility backlit LCD for real-time diagnostics and status updates. Its thermistor sensor can be extended up to 400 feet, offering incredible installation flexibility for remote sensing. Techs appreciate the selectable heating/cooling modes and field-adjustable differential (1°F to 30°F), ensuring tight control over temperature-sensitive equipment while preventing short-cycling through onboard microprocessor logic.

Key Benefits

• Universal Compatibility: Operates as a heavy-duty electronic replacement for mechanical controls in chillers, milk coolers, and warehouses.
• Remote Monitoring Ready: The 0-10V output signal (0V = -30°F, 10V = 220°F) enables easy interfacing with central monitoring systems.
• Precise Customization: Features a keypad lockout to prevent unauthorized tampering and a 1-degree resolution for setpoint accuracy.
• Rugged Reliability: Rated for 16 Amps (FLA) at 120V and 8 Amps at 240V, handling high-amp loads without secondary relays.
• Non-Volatile Memory: The internal EEPROM preserves all programmed settings during power loss, eliminating the need for reprogramming after outages.

Common Questions

Can the sensor wire be extended?
Yes, the included 8-foot thermistor probe can be extended up to 400 feet using standard 18-gauge or 22-gauge wire without sacrificing accuracy.

What does the 0-10V output do?
It provides a proportional DC voltage signal that mirrors the sensed temperature, which is essential for contractors integrating the control into a broader BAS or data logging setup.

How do I prevent staff from changing the setpoint?
The unit features a physical lockout switch located inside the NEMA 1 enclosure, which disables the front keypad to ensure system parameters remain at the technician’s specifications.
