DIGITAL CONTROLLER FOR REFRIGERATION (E) AND WITH DEFROST WITH ALARM OUTPUT

nbsp;

This device is a versatile low temperature controller for frozen products that can operate in refrigeration, heating or automatic mode. It manages the defrost start and end cycles only when necessary, based on the temperature of the evaporator. It has a timing function for collection of the residual refrigerant gas before defrost starts, improving performance of the refrigeration cycle and reducing power consumption. It has four relay outputs, one of which can be used to trigger an alarm or turn off lamps. It also has a configurable digital input that can be used for external defrost synchronism, night mode, door alarm or standby mode. It has a built-in buzzer and a configurable digital filter that increases the response time of the S1 sensor to avoid activating the compressor by quick temperature changes. It has a powerful 16A relay that can command directly up to 1HP compressors. It has a serial communication for connection to Sitrad - management software via internet.
