The WTH (Wireless Temperature Hub) shows all of your temperature channels on one color touchscreen. This article covers how the screen is laid out, what the color scale means, how to read the history graphs, and how to use the hub's physical button.
The Main Display
The WTH is a live monitoring dashboard. It shows every connected channel at once, updated several times a second, so you can watch all of your temperatures without switching between screens. There is nothing to navigate for day-to-day monitoring: the readings are always on view.
The screen is divided into two areas:
- Infrared channel tiles (the main area): a grid of tiles, one for each infrared sensor pod. These are the four infrared channels, numbered IR 1 to IR 4.
- Contact probe readouts (along the bottom): a row of smaller readings, one for each wired contact probe.
Only channels with a connected, working sensor are shown. A channel with nothing plugged in stays blank, so the screen shows only the points you are actually measuring.
Reading an Infrared Channel Tile
Each infrared channel tile shows three things at a glance:
- The current temperature, shown as a large number in Fahrenheit and colored on the temperature scale (see below)
- The recent low and high, shown at the upper corners of the tile, so you can see the range the channel has covered lately
- A history graph, a trend line that scrolls across the tile showing how the temperature has been moving over time
The history graph automatically zooms to fit the recent range: it centers on the average of the recent low and high and expands or contracts so the trend is always easy to read, even when the temperature is holding steady or swinging widely.
Reading the Contact Probe Row
Along the bottom of the screen, each connected contact probe shows its current temperature in Fahrenheit, colored on the same temperature scale as the infrared tiles. A probe that is not connected leaves its spot blank rather than showing a false value, so the row reflects only the probes you actually have attached.
The Temperature Color Scale
Every reading is colored so you can judge it at a glance without reading the number. The scale runs from cool to hot:
| Temperature | Color | What It Suggests |
|---|---|---|
| Cool (roughly 60 °F and below) | Blue | A cool surface |
| Normal (roughly 65 to 90 °F) | Neutral | An ordinary, unremarkable temperature |
| Warming (around 90 to 95 °F) | Shifts toward orange | Heating up |
| Warm (roughly 95 to 105 °F) | Orange | Running warm |
| Hot (around 110 °F and above) | Red | Running hot, worth attention |
The color changes smoothly between these points, so a reading that is climbing gradually shifts its color as it rises. A tile or readout turning orange or red is your cue to look closer at whatever that sensor is measuring.
Because the color follows the temperature, you can spot a developing problem across the whole screen at once. If one channel is glowing red while the rest are neutral or blue, that is the point to investigate first.
The Physical Button
The hub has a physical button for basic control:
- Restart the hub: press and hold the button for about two seconds. The hub restarts and resumes monitoring on power-up. Use this if the display ever needs a fresh start.
The hub also has a status light that indicates it is powered and running.
Touch
The screen is a touchscreen. For everyday use you do not need to touch anything: the hub shows all channels continuously on its own. Configuration and firmware updates are handled through the LF Audio AuralSync app over Bluetooth (see Menus and Settings and Firmware Updates).
Units
Temperatures are shown in Fahrenheit throughout the display.
When a Channel Is Blank
A blank channel means the hub is not receiving a valid reading from a sensor on that channel. This is normal for any port you are not using. If a channel you expect to see is blank, confirm the sensor is fully plugged in and correctly placed, then allow a few seconds for the hub to detect it. See Troubleshooting for more.
