What if my Sensor probe reading higher or lower than actual temperature?
If the sensor probe is placed too close to the wire, it will read higher temperatures than you will actually feel on the floor. That is because the cable itself can get to 132F in order to bring the thinset and tile to 80F, 85F or even 90F. If the sensor tip is placed too close to the cable, it may read the 80F temperature too quickly and turn off the unit too soon.
You can correct the sensor reading by using the OFFSET feature in the advanced settings of your thermostat. For example, if your thermostat says 80F but the floor really is only 75F, OFFSET your sensor by “-5” and give it 5 minutes to recalibrate or reset the thermostat completely. The sensor will now adjust to its new range and scale.
If your variance is wider than 10F, you may need to lift tile and reposition the sensor, or simply work with the ambient feature of the thermostat instead.
If it is reading significantly colder or warmer or temperature readings are sporadic, please contact your installer to see if the sensor probe was placed in the same conduit as the cold tail lead. Warmup recommends a separate conduit for both to avoid interference which may result in incorrect temperature readings.
