Digitális termosztát ZFX-ST3012 230V

Digital thermostat with two independent switching and measuring circuits, complete with an audio alarm for exceeding limit values.. Technical parameters:. - Working voltage: 110 to 220V AC. - Outputs: 2. - Relay: potential-free contact 250VAC/5A resistive load only. - Controlled temperature range: –50°C to 110°C. - Resolution: 0.1°C (above 100°C 1°C), accuracy 0.5°C in the range –10°C to 100°C. - Measurement frequency: 2×/sec. - Display color: red. - Measuring sensor: 2× NTC (10 kohm 0.5%), waterproof. - Sensor wire length: 1m. - Dimensions: 75×55×31mm. Instructions for use:. The thermostat allows temperature settings for two independent circuits. Switching on of the thermostat is indicated by LEDs OUT1 and OUT2 - green light.. To set the temperature on the left, briefly press the SET button and use the arrows to set the temperature. With another short press, you move to the temperature setting on the right.. One short press of the SET keys and one long press will take you to the settings menu on the left.. Press the SET key twice and press the SET key twice to get to the settings menu on the right.. Use the arrows to move through the menu. press SET briefly to go to the detailed settings of each function and press SET again to save the value. The settings are saved even after a few seconds without pressing the button.. Function:. HC-mode heating (H)/cooling (C). D-Temperature difference between on and off (1-30°C). LS-Alarm for low temperature (from -50°C to +109°C). Alarm signaled by sound, flashing red LED and "-L-" display. HS-Alarm for high temperature (from -49°C to +110°C). Alarm signaled by sound, flashing red LED and "-H-" display. CA-correction (calibration) of temperature indications (from - 10°C to 10°C). PT-Delay. Reset to factory settings by long pressing the arrows below the display.. Note on 220V AC equipment:. Connecting the device to mains voltage can be life-threatening and professional installation is required. Entrust this work to an electrician with valid decree 50/1978 §6 to §10.
