Installation and User Guide DEVIreg™ Hotwater
1 Introduction
DEVIreg™ Hotwater is a 4 channel electronic programmable controller. 3 additional chan-
cels 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)
