the controller, and can be used for control systems with any voltage up to 250 V AC .
In addition to 3 control modes, DEVIreg™ Multi has some special functions which can be
programmed for every channel: relay status – opened or closed for 'Heating On' mode,
channel activation or deactivation, sensor failure alarm, min . and max . temperature alarms,
cable failure monitoring, relay test, channel on/off, relay cycles' calculator, etc .
Hardware of DEVIreg™ Multi is based on the Danfoss controller type MCX08M2,
art . no . 080G0307, but is customized with special software .
