ETC COMMERCIAL TEMPERATURE CONTROLS 

An electronic temperature control for commercial HVAC/R at a surprisingly affordable price.

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, one and two stage capability, selectable heating/cooling modes and multi-voltage input, the ETC is one of the most versatile temperature controls available. 

DIGITAL DISPLAY
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 1F resolution.  Setpoint temperature, differential and mode of operation (heating or cooling) can  all be selected using the keypad and display. 

CHOICE OF ONE OR TWO STAGE MODELS
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 state models can be set up with overlapping heating or cooling stages. 

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. 

BUILT-IN SAFETY
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 setting by unauthorized personnel  The switch, which is located inside the enclosure, can be used to disable the keypad function.

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 -30F and 10 volts =220F.  

MAXIMUM APPLICATION FLEXIBILITY
  • Wide temperature range (-30F to 220F) and differential adjustment (1F to 30F)
  • Available in one and two stage models. 
  • Accepts 120/208/240 volt input.
  • User selectable heating/cooling modes for use in hundreds of applications. 
  • Replaces most electromechanical and electronic temperature controls. 
SAFETY FEATURES
  • Keypad lockout switch prevents tampering.
  • EEPROM memory retains control settings during power outage. 
  • On power up, time delay protects equipment from simultaneous restarts. 
OPTIONS
  • 24 volt input models
  • NEMA 4X outdoor enclosures
  • Analog output for remote temperature indication.
