All configuration for the WTH lives in one place: the Settings screen. Open it by tapping the gear icon in the top-right corner of the TEMPERATURES home screen. Settings is organized into five tabs across the top: Display, Channels, Devices, System, and About. Tap a tab to switch to it. Every change you make is saved automatically, so there is no separate save step. To return to the dashboard, tap the back control or the home title. For a tour of the home screen itself, see Display and Navigation.

Display
The Display tab controls the screen: how bright it is, whether it sleeps, how temperatures are shown, and the touch calibration.
| Setting | Options / Range | Default | What it does |
|---|---|---|---|
| Brightness | 5-100% | 100% | Sets the backlight level. Applies immediately as you adjust it, so you can dim the hub for a dark install. |
| Show Celsius | On / Off | Off (Fahrenheit) | Chooses the temperature unit used across the hub. Off shows °F; on shows °C. This is the same unit that the °F/°C toggle on the home screen switches. |
| Sleep when idle | On / Off | On | Lets the screen turn off after a period without touch to reduce glare and wear. Turn it off to keep the screen on at all times. |
| Sleep after | 10-240 seconds | 60 seconds | How long the hub sits untouched before the screen sleeps. Appears only when Sleep when idle is on. Tap the screen or short-press the front button to wake it. |
| Severity tint | On / Off | Off | When on, a channel tile gradually shifts color as its temperature climbs toward the over-temp threshold, giving you an early visual warning before it actually trips. |
| Colors | (theme editor) | LF Audio | Opens the theme editor, where you can pick a built-in color theme or adjust the colors the dashboard uses. Your choice is kept across restarts. |
| Calibrate Touch | (action) | 9-point calibration | Re-runs the guided 9-point touch calibration, the same one the hub runs the first time it starts. Tap each target as it appears. Use this if taps land off-center. |
If the touchscreen feels inaccurate, you do not have to dig through Settings. Press and hold anywhere on the screen for about 10 seconds to trigger the same recalibration directly.
Channels
The Channels tab sets the temperature alarm behavior and lets you rename each channel. Remember that the hub supports up to 8 sensors total: 4 infrared channels (named IR 1 through IR 4 by default) and 4 contact-probe channels (Probe 1 through Probe 4).
| Setting | Options / Range | Default | What it does |
|---|---|---|---|
| Over-temp threshold | 70-200°F | 110°F | The single temperature limit applied to every channel. When any channel reaches or passes it, that tile and the home status dot turn to a warning state. |
| Peak Hold (voice-coil) | On / Off | On | Infrared channels only. Briefly holds the highest reading so an infrared sensor aimed at a moving target still captures the true peak temperature. |
| Peak Hold window | 1-15 seconds | 1 second | How long Peak Hold keeps the peak value before it releases. A longer window holds a spike on screen for more time. Appears only when Peak Hold is on. |
| Channel Names | Text, up to 20 characters | IR 1-4, Probe 1-4 | Renames each channel so the dashboard reads in your own terms (for example "Sub Coil" or "Amp Terminal"). |
Over-temp threshold
The over-temp threshold is a single global limit that applies to all channels at once. There is no per-channel setting. Set it to the hottest safe reading you want to allow anywhere in the system, then the hub watches every connected infrared and probe channel against that one number. When a channel meets or exceeds the threshold, its tile recolors to a warning state and the status dot in the top-right of the home screen turns to warning. The range is 70°F to 200°F, and the default is 110°F. The threshold follows your unit choice, so if you turn on Show Celsius the range and value are shown in °C.
The WTH has no buzzer and no relay. The over-temp alarm is visual only: the tile and status dot change color, but the hub makes no sound and does not switch anything on or off. Watch the screen, or turn on Severity tint on the Display tab so a channel changes color gradually as it heats up and gives you warning before it trips.
Peak Hold (voice-coil)
Peak Hold is for the infrared channels. An infrared sensor reads the surface it is pointed at, so if it is aimed at a subwoofer voice-coil area that moves with the cone, the true hot spot passes through its view only briefly. Peak Hold catches that moment: it holds the highest reading for the length of the Peak Hold window (1 to 15 seconds, default 1 second) so the peak temperature stays on the tile long enough for you to see it instead of flickering past. Peak Hold has no effect on the contact-probe channels, which read a fixed surface and do not need it. Turn Peak Hold off if you prefer the infrared tiles to always show the live instantaneous reading.
Renaming a channel
To give a channel a name that means something to you:
- Open Settings > Channels and tap Channel Names.
- Tap the channel you want to rename (for example IR 1 or Probe 2).
- Enter a name of up to 20 characters using the on-screen keyboard.
- Confirm. The new name appears on that channel's dashboard tile and on its history graph.
To restore a channel's default name (IR 1 through IR 4, or Probe 1 through Probe 4), clear the field so it is blank and confirm. Renaming a channel does not change which sensor feeds it: names follow the port, and infrared channels always come before probe channels.
Devices
The Devices tab manages the LF Audio wireless displays that the hub streams temperatures to, such as the WDD, WDD-LITE, and WVC Knob. Sensors are not managed here: they are wired, so plugging one in makes its channel appear on its own.
| Setting | Options / Range | Default | What it does |
|---|---|---|---|
| Paired Displays | (list) | Empty | Lists every wireless display paired to the hub. Each entry shows the display type, its firmware version, its connection status, and its signal strength. |
| Pair New Display / Stop Pairing | (action) | Not pairing | Starts pairing so a nearby LF Audio display can join. The button reads Stop Pairing while the hub is searching. You can also start pairing by triple-pressing the front button. |
| Forget | (per display) | (action) | Removes one paired display from the list. The other paired displays stay connected. |
When you tap Pair New Display, the hub shows "Pairing Mode" and "Searching for display...", and the pairing indicator light flashes. When a display joins, the hub shows "Paired!" and "Connection successful", and the display appears in the Paired Displays list. To clear every paired display at once instead of one at a time, press and hold the front button; the hub clears all pairings and restarts. For a full walkthrough, see First Boot and Pairing.
System
The System tab is the hub's information and maintenance screen. The upper part is a read-only list of device details, useful when contacting support or checking a version. The lower part holds the maintenance buttons.
The read-only rows include: Model, Hardware version, Manufactured date, Firmware version, Sensor board version, Wireless Channel and Frequency, Bluetooth PIN, Device ID, MAC address, Boots, and Uptime. For what each of these means and when a value points to a problem, see System Diagnostics.
| Button | What it does |
|---|---|
| Start OTA Update | Checks for and installs newer firmware over your home WiFi. Stops with an "Up to Date" message if the hub already has the latest version. |
| Force OTA Update | Re-installs the current firmware version even when the hub is already up to date. Use it to repair an interrupted or misbehaving update. |
| Reset Settings | Restores the display and interface settings to their defaults and restarts the hub. Your paired displays and setup are kept. |
On the hub these buttons are named exactly Start OTA Update and Force OTA Update. Firmware updates need a home WiFi network, which you provide once through the LF Audio AuralSync app. For the complete update workflow and the progress screen, see Firmware Updates.
Reset Settings is a light reset: it returns display and interface preferences to their defaults and restarts, but it keeps your paired displays and channel names. To clear paired displays instead, press and hold the front button, or use a per-display Forget on the Devices tab.
About
The About tab is a simple credits and identity screen. It shows LF Audio, the product name Wireless Temperature Hub, and a one-line description noting that the hub provides multi-channel infrared and contact temperature monitoring. There are no adjustable settings on this tab.
