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 (the relay activates when the measured temperature exceeds the upper temperature limit). The ETC-200+ is suitable for both cooling and heating applications and is equipped with two relay outputs. In cooling mode, both the ETC-100+ and ETC-200+ offer a selectable delay time of 0 to 30 seconds. Additionally, an alarm sounds if the sensor connection is faulty or if the temperature falls outside the permissible range (-40 to +120 °C). In cooling mode, the ETC-200+ also features an automatic defrost function.
