76TECHNICAL 76 REGULATING DATASHEET ELECTRONIC THERMOSTAT ETL 011 | DC 12 to 48 V >>Large setting range >>Small hysteresis >>Optical operating display (LED) >>Change-over contact >>Signal application The electronic thermostat registers the surrounding air temperature and can switch a signal current via its internal relay with a potential-free change-over contact. Signal-processing devices can be controlled directly with the ETL 011. In order to control heating and cooling equipment, filter fans and signal devices the switch module DCM 010 or a similar device is needed. The LED integrated in the adjustment knob shows the closed status of the contact 1-2. When temperature is rising contact 1-2 opens and the LED turns off. In currentless state (no supply voltage) contact 1-2 opens. TECHNICAL DATA 1 Switch temperature difference 4 K ( 1 K tolerance) at +20 C (+68 F) Sensor element NTC Reaction time approx. 5 sec.
