• Page 3: Introduction 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 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 setting, with a scale from -10° to +10°C. An LED indicator shows standby periods (green light) and heating periods (red light).
