S-4 is selected according to the controller model and range. The appropriate version of S-4 is required for the combined functions of the T-2 Pro. The sensor is sold separately from the controller.

Choosing a compatible sensor

Check the controller model, the measured parameters, and the sensor range. An identical connector is not enough to prove compatibility.
