1Introduction
ECtemp 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 pro-
tection. 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).
