The 70/00438734 is a JUMO eTRON M compact Digital Electronic Thermostat for simple temperature control (heating or cooling). The measurement input permits the connection of resistance thermometers or thermocouples or standard current or voltage signals. The measured value is shown on a 3-digit backlit display. The switching states of relays K1 and K2 are indicated by two LEDs. The instrument incorporates a simple defrosting function as well as an operating hours counter, which can, for instance, be used to record the operating time of a cooling compressor.
