Product Usage Instructions

1. Introduction

The DEVIregTM 330 is an electronic thermostat designed for electric cabinets with DIN rail attachment. It requires installation via an all-pole disconnection switch. To measure and control the desired temperature, either a floor sensor or an external room sensor must be used. For more information on this product, visit devireg.devi.com.

2. Mounting Instructions

Follow the steps below to mount the thermostat:

1. Click the thermostat onto the DIN rail attachment.

Connect the thermostat according to the connection diagram.

Connection Diagram:

The screen of the heating cable must be connected to the earth conductor of the power supply cable using a separate connector.

Note: When using the wire sensor for floor heating, always install the sensor in a conduit.

Turn on the power supply.

3. Settings

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

For 8 mm HDF-based laminate, set hysteresis to 0.05.
For 14 mm beech parquet, set hysteresis to 0.10.
For 22 mm solid oak plank, set hysteresis to 0.13.
For carpet thickness suitable for floor heating up to 22 mm solid fir planks, set hysteresis to <0.17.

4. Warranty

A 2-year product warranty is valid for:

Faulty products due to defective design, materials, or workmanship. The decision to repair or replace the product will be at the discretion of Danfoss, and no extension of the warranty period following repairs undertaken is granted.

A: No, either a floor sensor or an external room sensor must be used to measure and control the desired temperature.

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). More information on this product can also be found at:

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 the 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 regulations 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:

Click the thermostat on to the DIN rail attachment.
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.
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 manufacturers 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.
