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 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).

1.2 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.

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.
