Installation and User Guide	DEVIreg™ Hotwater

1 Introduction

DEVIreg™ Hotwater is a 4 channel electronic programmable controller.. 3 additional chancels are not used in this constellation.. The device is DIN-rail mountable and is used for control of Devi Hotwatt cables.. Every channel (4) can be individually set up, this will allow for 4 different temperatures and disinfection schedules..

Universal analog channels’inputs can be selected via software between 7 types of temperature sensors including NTC 15 kOhm at 25 °C.. The controller has a LCD display, Modbus RS-485 serial interface and 110/230 V AC power supply.. Voltage to sensors is SELV..

DEVIreg™ Hotwater has 8 control relays – 2 sets of max.. 10 A and 6 sets of max.. 6 A; For this specific application 2, 10A and 2, 6A relays are used.. Relay control functions can be set to Hot-water maintenance and legionella control of a hot-water system by use of applicable heating cables.. Additionally, relay contacts are not connected to a voltage source inside the controller, and can be used for control systems with any voltage up to 250 V AC..

Hardware of DEVIreg™ Hotwater is based on the Danfoss controller type MCX08M2, art. no. 080G0307, but is customized with special software..

The product complies with the EN/IEC Standard “Automatic electrical controls for household and similar use”:

•EN/IEC 60730-1 (general)

•EN/IEC 60730-2-9 (thermostat)
