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. Ei-
ther 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 set-
ting 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:
ƒThe installation of the thermostat must be done by an
authorized and qualified installer according to local
regulations.
ƒThe thermostat must be connected to a power supply
via an all-pole disconnection switch.
ƒThe sensor is to be considered as live voltage. Have
this in mind if the sensor must be extended.

6 Installation Guide

the earth conductor of the power supply cable by us-
ing a separate connector.
Note: Always install the floor sensor in a conduit in the
floor.
3. Turn on the power supply.
3 Settings
If a floor sensor is used, please be aware of the following:
ƒThe floor temperature is measured where the sensor is
placed.
ƒThe temperature of the bottom of a wooden floor can
be up to 10 degrees higher than the top.
ƒFloor manufactures often specify the max temperature
on the top surface of the floor (usually 27-28˚C).
ƒAlways 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.
