HP Heat Pump
This widget belongs to the High-performance SCADA fluid system bundle — a collection of components designed for building detailed, high-fidelity fluid system diagrams on ThingsBoard dashboards.
It represents an industrial heat pump unit rendered as a front-facing assembly with a visible fan housing and motor casing. The widget combines monitoring and control: the current temperature reading is displayed directly on the widget face, and the on-widget arrow buttons let operators increment or decrement the temperature setpoint without leaving the dashboard. Use it in heating, ventilation, cooling, or refrigeration diagrams where real-time temperature visibility and quick setpoint adjustments are needed.
Key capabilities
Section titled “Key capabilities”- Display the current temperature reading on the widget face.
- Animate the fan rotation when the heat pump is in the running state.
- Let operators adjust the temperature setpoint using the on-widget up and down arrow buttons.
- Configure the valid temperature range and step size for setpoint adjustments.
- Indicate warning and critical states with configurable colors.
- Animate a blinking effect when the heat pump is in warning or critical state.
- Trigger separate dashboard actions when the widget is clicked in its warning state or critical state.
- Trigger a general dashboard action when the widget symbol is clicked in any state.
- Receive state data from device attributes, time series, alarm status, or dashboard state.

Troubleshooting
Section titled “Troubleshooting”Fan shows no rotation animation when running
| Cause | Solution |
|---|---|
Running action is set to Do nothing and value is False | Open the Running edit dialog, set the correct Action, and specify the attribute key. |
| Target device is not connected | Confirm that the selected device is online and actively sending data. |
Temperature value is not displayed
| Cause | Solution |
|---|---|
| Temperature action is Do nothing and no static value is set | Open the Temperature edit dialog and configure it to read from a time series key or attribute. |
| Device is not sending telemetry | Confirm the device is online and publishing the expected time series key. |
Arrow buttons do not update the temperature
| Cause | Solution |
|---|---|
| Update temperature is not configured | Open the Update temperature edit dialog and select Execute RPC, Add time series, or Set attribute. |
| Temperature value is already at the min or max | The widget clamps to the configured Temperature min / Temperature max range. Adjust these limits in the Appearance section if needed. |
Warning or critical color does not appear
| Cause | Solution |
|---|---|
Warning or Critical action is Do nothing and value is False | Configure the state parameter to read from an alarm status or a device attribute. |
| Alarm is not active on the device | Confirm that the device has an active alarm of the expected severity. |
Warning click or Critical click does nothing
| Cause | Solution |
|---|---|
| The heat pump is not currently in the expected alarm state | The Warning click handler only fires when the Warning state is active; Critical click only fires when the Critical state is active. Verify the alarm is active on the device. |
| Action is set to Do nothing | Open the Warning click or Critical click edit dialog and configure the desired navigation or action. |
