NOTE
Some solar controllers, the overheat protection is provided by a temperature sensor,S3,
which is wired directly to the solar controller same as sensors S1 and S2
In this case the mechanical overheat thermostat (S3) shown in this diagram is not required and
the solar pump is wired straight to the solar controller.
