Ranco ETC Commercial Temperature Control Thermostat

ETC-241000-000

The Ranco 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, 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. One finger is all you need to program it. The standard digital display and keypad allow the user to adjust the temperature settings with 1° resolution. Setpoint temperature, differential and mode of operation (heating or cooling) can all be selected using the keypad and display. When not in the programming mode, the display gives a constant readout of the sensor temperature. Annunciators on the liquid crystal display also indicate when the relay is energized. The ETC line includes both one and two stage models. On two stage controls, each stage can be set independently thus eliminating the bothersome task of calculating interstage temperatures. And two stage models can be set up with overlapping heating or cooling stages. The ETC is capable of remote temperature sensing up to 400 feet away from the control when using standard 22 gauge sensor wire. Every ETC model is equipped with diagnostic programs that check for hardware, software or system problems and display different error codes to indicate where the trouble is. The ETC also has a keypad lockout switch to prevent tampering with the control settings by unauthorized personnel. The ETC display temperature may not be calibrated in the field.

  • Agency Approvals: UL listed, file E94419, Guide XAPX & CSA certified, file LR68340. class 4813 02.
  • Remote temperature sensing: The ETC is capable of remote temperature sensing up to 400 feet away from the control when using standard 22 gauge sensor wire.
  • Optional analog output: ETC models are available with a 0 to 10 volt analog output that can be used for remote temperature indication or as input to a central monitoring system. This signal is a linear representation of the sensor temperature with 0 volt –30°F and 10 volts = 220°F.
