If your Induct Temperature is showing out-of-range temperatures like -90 degrees, +90 degrees, etc. there could be a few reasons for that to happen, and can be rectified by following the steps below.
1️⃣ Check the placement:
Investigate and make sure that Induct sensor thermostat end is not touching any condensed water or interior part of the indoor coils as that can cause false data and display false readings on the controller.
2️⃣ Replace the Sensor:
If the placement of the censor is fine replace the CDTS Sensor in order to rectify the issue.
3️⃣ Change the CPU C225:
If the issue persists, even after replacing the sensor itself, then it could be the CPU CDTS port as well causing the false data reading. in that case, we recommend you to change the CPU C225 and that should resolve your problem.
