Engineering Mode

1. Press and hold the and keys simultaneously for more than 5 seconds to enter Engineering Mode for parameter setting.

2. Press or to select the parameter, and then press to confirm the parameter selection.

After confirming the parameter selection, the parameter value in the upper right corner will start flashing.

3. Press the or key to adjust the parameter value, and then press the key to confirm.

4. Repeat the above 2 steps to set other parameter values.

5. Press to exit the project mode

Setting Parameter

  • P 1 (Set Pt Min) - Set the minimum temperature setting value. The default setting is 12.5°C (55°F). The user selects the minimum setting value for the room operation unit. The set value limit is ultimately defined in the controller. The upper limit value is Set Pt Max. Adjust the step size to 1°F or 0.5°C.
  • P 2 (Set Pt Min) - Set the minimum temperature setting value. The default setting is 35°C (95°F). The user selects the maximum set value that the sensor should request. The set value limit is ultimately defined in the controller. The lower limit value is Set Pt Min. Adjust the step size to 1°F or 0.5°C.
  • P 3 (Disp Temp?) - Determines if the temperature value is displayed. The default value is YES.
  • P 4 (Disp Occ?) - Determines whether the Occupancy status is displayed. The default value is YES.
  • Note: This setting only enable/disable the display of the occupancy status, it does not enable/disable the occupancy override button functionality.
  • P 5 (T Cal) - Allows the user to field calibrate the temperature display and output through a bias adjustment. The default value is +0°C(0°F). Adjustments may be made between -3°C (-5°F) and +3°C (+5°F), in 0.2°C (0.5°F) increments.
  • P 6 (Fahrenheit or Celsius) - Allows the user to set temperature units. The options are Fahrenheit and Celsius, the default is Celsius.
  • P 7 (Factory Defaults) - Allows the user to reset all parameters to factory defaults. The available options for this parameter are YES and NO.
  • d 1 (Hardware version) – Display the hardware version and cannot be set.
  • d 2 (Software version) – Display the software version and cannot be set.
