Ranco ETC Temperature Controller
The Ranco ETC is a microprocessor-based electronic temperature control designed to provide on/off control for commercial heating, ventilating, air conditioning, and refrigeration. The ETC is equipped with a liquid crystal display (LCD) that provides a constant readout of the sensed temperature, and a touch keypad that allows the user to easily and accurately select the set point temperature, differential and heating/cooling mode of operation. The ETC NEMA Type 4X control can accept either 120 or 208/240 VAC input power.

Features and Benefits:• Wide set point temperature range (-30ºF to 220ºF) and differential adjustment (1ºF to 30ºF)
• Simple keypad programming of set point temperature, differential and cooling/heating modes.
• LCD readout of sensor temperature, control settings, relay status and onboard diagnostics.
• Remote temperature sensing up to 400 feet.
• SPDT output relay.
• User selectable Fahrenheit/Celsius scales.
• Lockout switch to prevent tampering by unauthorized personnel.
• NEMA Type 4X enclosure rated watertight for outdoor applications.
• Designed to meet Article 547 of the National Electrical Code for use in agricultural buildings.
Applications:All ETC NEMA Type 4X controls have enclosures rated watertight for outdoor use. With its wide temperature setpoint range and selectable heating and cooling modes, the ETC can be used for a wide variety of applications including bulk milk coolers, refrigerated storage, cooling towers, unit heaters, ventilation fan cycling and trace heating. In addition, the ETC NEMA Type 4X control is designed to meet the requirements of Article 547 of the National Electric Code for use in agricultural buildings such as poultry houses and livestock barns.
