Installation Guide
The DEVIregTM 330 is an electronic thermostat designed for installation in electric cabinets with DIN rail attachment. Ensure installation via an all- pole disconnection switch. Use either a floor sensor or an external room sensor for temperature measurement and control.
Mounting Instructions
Placement Guidelines:
- Click the thermostat onto 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 using a separate connector. When using a wire sensor for floor heating, always install the sensor in a conduit. Turn on the power supply after installation.
Settings
If using a floor sensor, consider the following hysteresis values for different flooring types:
- 0,05 for 8 mm HDF based laminate
- 0,10 for 14 mm beech parquet
- 0,13 for 22 mm solid oak plank
- < 0,17 for Max. carpet thickness suitable for floor heating
- 0,18 for 22 mm solid fir planks

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).

Technical Specifications
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 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 accord-ing 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:
-
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 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.
