RED31

Thermostat with compressor activation and one temperature probe. Available with Communication RS485.

FUNCTIONING

The DREF11 controller electronic instrument, designed and manufactured to measure, display, and is an control temperatures between – 50 + 150°C, and can control timed defrost cycles through compressor OFF. It is particularly suitable for applications in positive temperature refrigeration plants. The thermostat can control a compressor , with an absorption of up to 8 or 30 A, directly through a relay.

The compressor is activated when the temperature rises and reaches the set point + differential value and is stopped when the temperature drops back to the set point value .

The thermostat can also control timed defrost cycles through compressor stop. Both the interval time between defrost cycles and the duration of the latter can be set by the end-user.

The temperature is detected through a semiconductor TC probe that can be installed up to 10 m / 30 ft N from the thermostat without need for instrument re-calibration. The temperature detected by the probe(s) is visualized on a 3 digit red LED display.

MAIN FEATURES

SIMPLE PROGRAMMING: instrument programming is easy to carry out through the front panel keypad with no need for tools or complicated procedures.

LIMITED NUMBER OF PARAMETERS: all instrument operating modes can be programmed through a limited number of parameters.

DECIMAL POINT: it is possible to select the decimal point option in order to view and manage the decimal value. This is possible only with positive numbers.

SELECTING THE UNIT OF MEASURE: the user can choose between two units of measure to display the temperature, i.e., either in ° Celsius or in ° Fahrenheit.

TROUBLESHOOTING: the thermostat can detect and signal the following defects: a not connected, interrupted or short-circuited probe; when the detected temperature exceeds the temperature limit of the probe; a loss of data or a data memory failure; a temperature exceeding the high or low alarm limits.
