The temperature controllers ETC-100+ and ETC-200+ are characterized by their ease of use and reliability. The ETC-100+ model is specifically designed for cooling applications, as the relay activates when the measured temperature exceeds the upper temperature limit. The ETC-200+ is suitable for both cooling and heating applications and features two relay outputs. In cooling mode, both the ETC-100+ and ETC-200+ offer a selectable delay time between 0 and 30 seconds. Additionally, an alarm sounds if there is a fault in the sensor connection or if the temperature falls outside the permissible range (-40 to +120 °C). In cooling mode, the ETC-200+ also includes an automatic defrost function.
