Condition: 100% brand new_x000D_ Item type: Temperature Controller_x000D_ Material: ABS flame retardant plastic case_x000D_ Color: As picture shown_x000D_ Weight: Approx. 130g _x000D_ Power supply voltage: 110-220VAC 10%, 50/60Hz (or DC12V / DC24V)_x000D_ Measuring and controlling temperature range: -50+110_x000D_ Resolution: 0.1C_x000D_ Accuracy: 1_x000D_ Accuracy: 1_x000D_ Relay output contact capacity:_x000D_ Heating: 10A/240VAC,_x000D_ Cooling: 10A/240VCA_x000D_ Sensor h type: imported NTC sensor, cable length 1m/3.3ft_x000D_ _x000D_ Description:_x000D_ P0. Cooling and heating mode_x000D_ Please set to C for high temperature start as cooling mode_x000D_ Low temperature start is heating mode, please set to H_x000D_ P1. Hysteresis setting_x000D_ In heating mode (H): the measured value the set value-when the hysteresis starts to output the heating to the set value and stops._x000D_ In the cooling mode (C): when the measured value the set value + hysteresis, the output cooling is started and the set value stops._x000D_ P2. The highest setting range: the highest value does not exceed this value when setting the temperature_x000D_ P3. The lowest setting range: the lowest value when setting the temperature is not lower than this value_x000D_ P4. Temperature correction_x000D_ When there is a deviation between the measured temperature and the standard temperature, you can use this function to correct. The corrected temperature = the temperature before correction + the corrected value._x000D_ P5. Delay start time unit: minute_x000D_ When controlling the refrigeration of the compression engine equipment, the delay time can be set according to the needs. The equipment will not start immediately when the controller is output, and it needs to start after the set delay time is run._x000D_ P6. High temperature alarm_x000D_ When the measured value is greater than this value, the screen displays --- and an alarm will sound, and the output will be forcibly disconnected._x000D_ P7. Data lock function_x000D_ Turn on the data lock to keep the current setting unchanged. At this time, the set temperature and function are invalid. If you need to modify it, you need to turn off the data lock function._x000D_ P8. Restore factory settings_x000D_ Long press SET to switch to P8, press SET once to set to on, press for Rst to restore factory settings_x000D_ You can also press and hold the +-key and hold the power-on self-test and restore factory settings._x000D_ Instructions for use_x000D_ Please connect the power supply according to the parameters and wiring diagram, and connect the cooling or heating equipment to the output terminal._x000D_ Enter the internal settings to select heating (enter P0 to select H) or cooling (enter P0 to select C) mode as needed._x000D_ Setting temperature method: press Set once and the screen flashes, press up and down to set the desired temperature, press for Rst to confirm and return to the OUT indicator of the panel: flashing indicates the delay of cooling or heating start, and constant light indicates output_x000D_ Nixie tube: display LLL for open circuit of the sensor; display for HHH for exceeding the measuring range and the thermostat will be forced to power off; display --- for high temperature alarm.
