Can you establish what the purpose of the temperature sensors is, and if these are internal to ISIS or require an external temperature input.
The temperature probes would be used to improve the accuracy.
Electronic sensors like the accelerometers and rotation sensors in the ISIS often have a slight temperature sensitivity. For the same actual acceleration, the sensor may read slightly higher or lower based on the temperature - few percent maybe. The effect can be characterized quite accurately (sometimes done for each individual part). Then by measuring the temperature of the sensor, the software can compensate for it.
The temperature sensors would be measuring the temp of the sensor chips within the ISIS box, not an external or ambient temp.
