• Temperature Setting
  After the temperature controller is connected to the power, the actual temperature is shown on the red
  display. When you press the SET key, the blue display will flash. Press UP and DOWN keys to adjust the
  temperature.
  P0: Working Mode
  This value should be set when you start using the thermostat. If it is used for heating, this parameter
  should be set to “H”. Otherwise, if used for cooling it should be set to “C”.
  P1: Hysteresis
  The difference between the temperature at which the thermostat switches off – and the temperature at
  which it switches on again.
  Example: We set the heating mode and the temperature is 37~40°C – The hysteresis is 3°C.
  P2-P3: Setting Limits
  These functions set the limit values of the temperature range. Under the normal state, the setting range is
  between -40°C and +120°C. If you don’t need so big range, you can set the values of these parameters to
  shorten it.
  Example: P2 is set to 50°C, P3 is set to 20°C – The temperature can be set from 20°C to 50°C.
  P4: Temperature Correction
  This function is used to correct the temperature in case there’s a deviation between the measured
  temperature and the actual temperature.
  Example: We measure the temperature of 25.6°C and the actual temperature is 25.8°C – You can set P4
  to 0.2°C, so the displaying temperature will be 25.8°C.
  P5: Delay Start
  This function is generally used for cooling the refrigeration compressor. So, if you purchase the
  thermostat for the refrigerator, this value has to be set to 3-6 minutes (depending on the size of the
  compressor). If it doesn’t control the compressor, this value should be set to 0.
  P6: High-temperature Alarm
  When the actual temperature exceeds the upper temperature limit of +120°C, the thermostat will display
  flashing “CCC” on the red display. In case of a short circuit, the blinking “LLL” message will be shown
  on the red display.
  P7: Data Lock
  If you need to prevent other people from changing your set temperature, you can set P7 to ON after
  finishing the setting of the parameters. After setting to ON, the temperature and the internal parameters
  cannot be changed.
  P8: Restore Factory Settings
  By setting P8 to ON, all the settings will be reverted to their factory default.
  P9: Temperature Scale
  You can switch between Celsius (°C) and Fahrenheit (°F) temperature scale by modifying value of this
  parameter (“HS” – Celsius, “FC” – Fahrenheit).
  Setting Examples
  Cooling Mode
  Controlling refrigeration equipment will stop cooling when the temperature is 25°C and start cooling
  when the temperature is 30°C. To set the working mode like this, follow the next steps:
  1. In the state of displaying the normal temperature, press the SET key to get the flashing numbers
  on the blue display; find the value 25.0°C by navigating with UP and DOWN buttons and finally
  press the RESTART key to confirm and get back to display state.
  2. To access the parameter setting mode, press the SET key and hold it for 5 seconds until “P0”
  appears on the screen. Then press the SET key to access the P0 code parameter. By pressing UP /
  DOWN, you can adjust between different modes. Choose “C” mode and press the RESTART key
  to confirm and get back to display state.
  3. Go to parameter setting mode again by holding the SET key for 5 seconds. When P0 is displayed
  on the screen, press the UP button to adjust to the code P1 (hysteresis) and then press SET to
  access the P1 code parameter. Adjust the value to 5.0 by navigating with UP/DOWN buttons and
  finally press the RESTART key to confirm and get back to display state.
  If you need to set other parameters, please refer to above settings.
  Heating mode
  Controlling heating equipment will stop heating when the temperature is 30°C and start heating when the
  temperature is 25°C. To set the working mode like this, follow the next steps:
  1. In the state of displaying the normal temperature, press the SET key to get the flashing numbers
  on the blue display; find the value 25.0°C by navigating with UP and DOWN buttons and finally
  press the RESTART key to confirm and get back to display state.
  2. To access the parameter setting mode, press the SET key and hold it for 5 seconds until “P0”
  appears on the screen. Then press the SET key to access the P0 code parameter. By pressing UP /
  DOWN, you can adjust between different modes. Choose “H” mode and press the RESTART key
  to confirm and get back to display state.
  3. Go to parameter setting mode again by holding the SET key for 5 seconds. When P0 is displayed
  on the screen, press the UP button to adjust to the code P1 (hysteresis) and then press SET to
  access the P1 code parameter. Adjust the value to 5.0 by navigating with UP/DOWN buttons and
  finally press the RESTART key to confirm and get back to display state.
