Digital temperature programmable controller EVCO EV3X21N7 compact size with energy saving function for refrigerated cabinets, display cases, refrigeration units, cooling tables.
EVCO EV3X21N7 - Digital controller with programmable cooling modes, designed to control a static refrigeration unit with an output compressor control relay. Colored icons displayed on the display show the current state of the unit. The duration of the defrost cycle is determined by the compressor shutdown time interval. Upon request, a device with an audible alarm, a serial port, a Modbus communication protocol for connection to the RICS monitoring system, with an EVKEY parameter copying system and an output for connecting a remote EVT100 temperature indicator is available. The controllers are available in a standard 74 x 33 mm case with a 13 mm high LED display with high resolution, 2 ½ -digit (with a decimal point and multifunctional LED indicators) and three control buttons (setup + on / standby mode, up and down). Easy installation in the panel is ensured by the clips included in the delivery set. Transfer and loading of controller configuration parameters is carried out using the EVKEY programming key (ordered separately); this operation is possible provided that the models are equipped with a serial port (optional).
