3Installation Guide
1 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 wire sensor or an external air sensor must be used
to measure and control the desired temperature.
The thermostat has a button to adjust the temperature set-
ting, with a scale from +60 °C to +160 °C. An LED indicator
shows standby periods (green light) and heating periods
(red light).

1.2 Safety Instructions
Make sure the mains supply to the thermostat is turned off
before installation.
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.

Installation Guide6
• If temperature wire sensor is applied on conductive
surface it must be installed with additional electrical
insulation.
• Caution: temperature sensor, heated surface and heat-
ing cable could have really high temperature.
• Sensor, conduit, fixing materials, etc. should be speci-
fied to be able to withstand temperatures applied by
application.
• Caution: Temperature sensor with silicon cable should
not be installed in concrete, aggressive and corrosive
environment, etc.
2 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:
1. Click the thermostat on to the DIN rail attachment.
2. Connect the thermostat according to the connection
diagram.
