DEVIreg 330 Electronic Thermostat Installation Guide

DEVIreg 330 Electronic Thermostat

Introduction

• DEVIreg™ 330 is an electronic thermostat to be installed in electric cabinets with DIN rail attachment. The thermostat must be installed via an all-pole disconnection switch.
• Either a floor sensor or an external room sensor must be used to measure and control the desired temperature.
• The thermostat has a button to adjust the temperature setting with a scale from +5 to +45°C. An LED indicator shows standby periods (green light) and heating periods (red light).

Safety Instructions
Make sure the mains supply to the thermostat is turned off before installation.
IMPORTANT: When the thermostat is used to control a floor heating element in connection with a wooden floor or similar material, always use a floor sensor and never set the maximum floor temperature to more than 35°C.

Please also note the following:

• The installation of the thermostat must be done by an authorized and qualified installer according to local regulations.
• The thermostat must be connected to a power supply via an all-pole disconnection switch.
• The sensor is to be considered as live voltage. Have this in mind if the sensor must be extended.
• Always connect the thermostat to continuous power supply.
• Do not expose the thermostat to moisture, water, dust, and excessive heat.

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 it will be exposed to direct sunlight.

Follow the steps below to mount the thermostat:

1. Click the thermostat on to the DIN rail attachment.
2. Connect the thermostat according to the connection diagram.

The screen of the heating cable must be connected to the earth conductor of the power supply cable by using a separate connector.
Note: When you use the wire sensor for floor heating, always install the sensor in a conduit.

3. Turn on the power supply.

Settings

If a floor sensor is used, please be aware of the following:

• The floor temperature is measured where the sensor is placed.
• The temperature of the bottom of a wooden floor can be up to 10 degrees higher than the top.
• Floor manufactures often specify the max temperature on the top surface of the floor (usually 27-28˚C).
• Always use a floor sensor to control floor heating.
  Without a floor sensor, the temperature control may be less accurate and you risk overheating the floor.
