Configure Temperature Control Parameters

This section describes how to configure the temperature control related parameters of the device, which includes:

  • Temperature Control
  • Open Window Detection
  • Freeze Protection

Configure Temperature Control Parameters

The device supports controlling the temperature during the heating period.

Prerequisites: Motor Stroke Calibration is successful.

Steps:
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. In the General page, enable Temperature Control.

  4. Select the Temperature Control Algorithm and configure the related parameters.
    • Built-in PID: Automatically adjusts the valve opening according to the ambient temperature and the set temperature.
    • Platform Algorithm: Local target changes are reported immediately. The device executes valve opening commands from the platform without local calculation. If the platform times out, the configured fallback strategy is applied.
      Parameter Description
      Temperature Control Algorithm Timeout Time The device will time out if it receives no command from the platform within the specified time. Range: 1-1440 min. Default: 30 min.
      Platform Algorithm Timeout Control Strategy

      Continue control with Current State: Continue temperature control based on the last data received from the platform until new data is received.

      Switch to Built-in PID Algorithm: Switch to the built-in PID algorithm until new data is received from the platform, then switch back to the platform algorithm.

      Close the valve: The device closes the valve and stops temperature control until new data is received from the platform, then resumes temperature control.
  5. Select the Temperature Control Mode and configure the related parameters.
    • 0-5 Scale Mode:
      Parameter Description
      Target Temperature for Each Scale Level Set the target temperature for each scale level. Range: 5-35 °C.

      Default values: Level 0 = 7 °C, Level 1 = 12 °C, Level 2 = 16 °C, Level 3 = 20 °C, Level 4 = 23 °C, Level 5 = 26 °C.
      Target Scale Level Set the target scale level for device control.
      Target Scale Level Display Time The target scale level display time after pressing any button. Range: 1-10s , Default: 2s.
    • Integrated Control Mode: Automatically adjust to target temperature via the device's algorithm, and support receiving valve opening downlink control commands.
      Parameter Description
      Target Temperature Set the target temperature for device control. Range: 5-35 °C.
      Target Temperature Regulation Range Set the adjustable range of the target temperature. Range: 5-35 °C.
      Target Temperature Resolution Select the resolution of the target temperature. Options:

      0.5: Increase or decrease target temperature by 0.5 each time.
      1: Increase or decrease target temperature by 1 each time.
      Target Temperature Display Time The target temperature display time after pressing any button. Range: 1-10s , Default: 2s.
    • Valve Opening Control: Adjust the valve opening status directly to control the temperature.
      Parameter Description
      Target Valve Opening Set the valve opening percentage. 0% means fully closed and 100% means fully open.
  6. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Result
During the heating period and not executing any schedule event, the device will control the temperature according to the above settings.

Configure Open Window Detection Parameters

The device supports detecting the window open status to stop invalid temperature control, thus saving energy. The following steps enable automatic detection of the window open status. In addition, the device supports manual control of the window open status via downlink commands.

Prerequisites: Temperature Control is enabled.

Steps:
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. In the General page, enable Open Window Detection and configure the related parameters. The following page is displayed.

    Parameter Description
    Cooling Rate Set the dropping ambient temperature per minute. When the rate reaches the preset value, it is considered a window-open status. Range: 2~10 °C/min.
    Valve Status Select the valve status during the window-open status. Options: Remains unchanged, Close Valve.
    Stop Temperature Control Time The interval to stop temperature control after detecting a window-open status. If the window-open status is not released within this interval, the device will re-detect the window-open status. Range: 1~1440 min, Default: 30 min.
  4. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Result
When the device detects that the cooling rate reaches the preset value, it sends an open window alarm packet and stops temperature control.

The open-window alarm is cleared when any of the following conditions is met:

  • Reach the set temperature control stop time.
  • The ambient temperature shows an upward trend for at least 10 minutes.
  • A release command is received from the platform.

After the alarm is cleared, the device sends an open-window alarm release packet and resumes temperature control.

Configure Freeze Protection Parameters

The device supports opening the valve to avoid freezing when detecting that the ambient temperature is too low.

Prerequisites: Temperature Control is enabled.

Steps:
  1. On the homepage of ToolBox, click Setting to enter the Setting page.
  2. On the top bar, select Device tab.

  3. In the General page, enable Freeze Protection and configure the Freeze Protection Temperature. The following page is displayed.

  4. Click Write in the lower right corner, and put the NFC detection area of the phone close to the NFC antenna of device. If the configuration succeeds, the following page is displayed.

Result
When the device detects that the ambient temperature is lower than freeze protection temperature, it sends a freeze protection trigger packet and starts temperature control.

When the device detects that the ambient temperature is higher than freeze protection temperature for over 2 hours, it sends a freeze protection release packet and keeps current valve opening status.
