Sensor compatibility with TST 770Updated 7 months ago

TST 770 models (with touchscreen) are backward-compatible with most TST sensors. If the date code on the sensor is later than 4519, the sensor will work with a 770 system. See photo below.

If you are having trouble pairing the sensor, be sure the CR2032 battery is fresh and you're not near any sources of radio interference (including atomic clocks and other travel trailers).
