Ranco’s ETC controls offer a fully-featured electronic replacement for electrical-mechanical temperature controls used in many commercial refrigeration applications. With its wide temperature range, one- and two-stage capability, selectable heating/cooling modes and multi-voltage input, the ETC is designed to provide application flexibility. Models available include 120/208- 240V AC and 24V AC, as well as single stage and two stage.
Common Applications Include:
- Walk-in and reach-in refrigerators
- Milk coolers
- Refrigerated display cases
- Any refrigeration system requiring temperature control
- Staging heating/cooling
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 you 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 and shows when the relay is energized. On two stage controls, each stage can be set independently to eliminate the 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.
