Measure mode Single temperature: T1 or T2
Differential temperature: T1 - T2 or T2 - T1
Average temperature: 0.5 x (T1 + T2)
Minimum temperature: lowest of T1 and T2
Maximum temperature: highest of T1 and T2
Sensor backup Single or average mode: failure on one sensor activates automatic
switchover to the other sensor
Sensor drift monitoring Single or average mode: adjustable acceptance level of the differential
temperature of sensor 1 and 2
