The Ranco® Electronic Temperature Control (ETC) is a microprocessor-based family of temperature controls designed to provide on/off control for commercial heating, cooling, air conditioning, and refrigeration applications. With its wide temperature range, one and two stage capability, selectable heating/cooling modes and multi-voltage input, the ETC is one of the most versatile temperature controls available. Unlike many electronic controls, the ETC is simple to install and set-up. •Wide temperature range (-30 F to 220 F). •Adjustable differential range (1 F to 30 F). •LCD Digital Display. ◦Temperature at the sensor. ◦Control settings. ◦Relay status. ◦Onboard diagnostics. •Simple Key Pad settings. •Remote temperature sensing - up to 400 feet. •Selectable Heat or Cool modes. •Selectable Fahrenheit or Celsius modes. •One Horsepower output relay. •Concealed lockout switch to prevent tampering. •Both one and two stage models available. •O-10 VDC analog output available. •Settings retained in the event of a power failure. •Sensor included with control
