Here is some interesting information from the Pressure Pro manual.
"HIGH TEMPERATURE ALERT – When the temperature at the Sensor hits approximately 210F, an alert is sounded. The Monitor Display will flash “2.1.0” and provide an audible alert (like the 25% low alert). When alert sounds, pull over and check for problems with the tire, brakes, bearings and such."
"Note: PressurePro Sensors take a sample of your tire pressure every 7 seconds, and report new Update Pressure readings to your Monitor every 5 minutes. Sensors send Update signals through short bursts. If at any time your pressure hits a low or high pressure alert level, it will override the 5 minute Update alert and timing, and send a reading immediately to your Monitor. A Low Pressure Alert Transmission differs from regular update alerts in that it sends a longer, stronger RF transmission that emits continuously while the wheel rotates a number of times. This stronger and longer transmission helps assure that an Alert Signal will be received, even through most interference."
As I have indicated before if I had it to do over I would have kept my Pressure Pro system and had purchased new sensors on their battery replacement program.
One feature I really like about the TST system is that it continuously scrolls the tire pressures. The Pressure Pro requires you to operate buttons on the display to scroll through the tires.
More of a distraction while driving.
I watch my pressures while driving looking for any significant pressure difference on each axle or like tires such as the 4 on the 5th wheel.
The Pressure Pro does monitor temperature and alarms on high temperature. Just it does not display temperatures.
