DEVIreg™ Hotwater
DIN-rail programmable controller for Hotwater maintenance

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 Hot watt 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)

Safety Instructions

Make sure the mains supply to the controller is turned off before installation.
Please also note the following:

• The installation of the controller must be done by an authorized and qualified installer according to local regulations.
• The controller must be connected to a power supply via an all-pole disconnection switch.
• Always connect the controller to continuous power supply.
• Do not expose the controller to moisture, water, dust and excessive heat.

Note: Product is designed for Over Voltage Category II. When used, installation must be equipped with transient protection.

Mounting Instructions

Please observe the following placement guidelines:
Install the thermostat in an electric cabinet with DIN rail attachment or a separate DIN attachment according to local regulation on IP classes.
Do not place the thermostat in a way that will expose the controller to direct sunlight.
Follow the steps below to mount the thermostat:

1. Click the thermostat on the DIN rail attachment.
2. Connect the thermostat according to the connection diagram, see page 4.
3. The screen of the heating cable must be connected to the earth conductor of the power supply cable by using a separate connector.
4. Turn on the power supply.

Note: Always install the sensors at assumed hottest and coldest locations on the respective pipe, and in direct contact with the pipe (2 sensors pr. heating circuit)
