Ranco ETC-112000-000 Control

The Ranco ETC-112000-000 is a versatile digital temperature controller designed for precise electronic sensing in HVACR applications. This SPDT NEMA 1 control operates on a 24V AC input and supports a wide temperature setpoint range from -30°F to 220°F. Engineered as a dependable replacement for traditional electromechanical thermostats, it features a selectable differential of 1°F to 30°F, allowing technicians to fine-tune cycles and prevent short-cycling of compressors or heating elements. The device utilizes a thermistor sensor for high-accuracy readings, which are displayed on a clear LCD screen that confirms both current temperature and system status. Its non-volatile memory ensures all programmed settings are retained during power losses, making it a reliable choice for commercial refrigeration, walk-in coolers, and space heating applications that require the Ranco ETC series reliability.

• Universal Application: The broad setpoint range and SPDT switching allow for both heating and cooling configurations.
• Precise Calibration: Digital sensing eliminates the drift issues common in bulb-and-capillary style controllers.
• Easy Field Programming: The keypad interface allows for instant adjustments to setpoints and differential without specialized tools.
• Integrated Diagnostics: The system automatically identifies sensor failures, reducing troubleshooting time on-site.
• Compact NEMA 1 Housing: Designed for easy mounting in clean, dry environments typical of mechanical rooms.

Can the sensor leads be extended for remote monitoring?
Yes, the thermistor sensor leads can be extended up to 400 feet using 18 AWG shielded cable to maintain signal integrity over long distances.

Is this controller compatible with 120V or 240V equipment?
While the controller requires a 24V AC power supply, the SPDT relay contacts are rated for various loads, including pilot duty and motor loads up to 1/2 HP at 120V or 1 HP at 240V.

How do I switch between Fahrenheit and Celsius?
The unit features a simple programming sequence via the keypad that allows the display to be toggled between °F and °C scales.
