3Installation Guide
1 Introduction
DEVIreg™ 330 is an electronic thermostat to be installed in
electric cabinets with DIN rail attachment. Used primarily for
controlling a lower temperature range as by frost protection.
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 -10° to +10°C. An LED indicator shows
standby periods (green light) and heating periods (red light).
