ITEM NAME:Xh-W1504 Tec Semiconductor Cooler Thermostat Automatic Constant Temperature I2M4 Xh-W1504 Tec Semiconductor Cooler Thermostat Automatic Constant Temperature I2M4 ON/OFF' key:Power switch button(Long press for 3second);'Set' key:Long press enter into internal menu to set parameter P1-P6;'+' key:Increase the Set Temperature Value at normal display mode by short/long press;Change set parameter a menu mode.;'-' key:Reduce the Set Temperature Value at normal display mode by short/long press;Change set parameter a menu mode. P1:Working Mode.'A' is automatic mode, which is to automatically switch TEC anode and cathode to achieve heating and cooling;'H' is the heating mode;'C' is the cooling mode. P2:Return Temperature.That is to set range for Set Temperature Value.If we set the Set Temperature Value is 25celsius and the Return temperature is 0.5celsius.So the temperature range is 24.5~25.5celsius.Start heating mode if the current test temperature is lower 24.5celsius.Start cooling mode if the current test temperature is higher 25.5celsius. P3:Temperature Correction. This function can be used when the measured value and the actual value are biased.Corrected value = measured value + set value. If the current measured temperature is 25.8 degrees Celsius and the correction value is -0.2 degree, the actual value shown after the return is 25.8-0.2, which is 25.6 degrees Celsius. P4: Delay Time. Module needs to switch positive and negative poles due to constant temperature during normal work of TEC.At this time, the temperature difference between the hardware is relatively large.Therefore, a delay is required to ensure heat dissipation and return to normal ambient temperature.Re-start positive and negative switching to protect TEC's service life. Name: TEC Semiconductor Cooler Temperature Controller Model: XH-W1504 Temperature control: -50 to 110Celsius Temperature control mode: Bit control. Control temperature accuracy: 0.1Celsius Refresh rate: 4 times/second Input vol.P1:Working Mode. 'A' is automatic mode, which is to automatically switch TEC anode and cathode to achieve heating and cooling;'H' is the heating mode;'C' is the cooling mode. P3:Temperature Correction.
