Answer to Question 1

A thermistor is a solid-state chip that changes its voltage output
according to the temperature. It is preferred for its superior accuracy and ability to
hold temperature closer to the set point than a thermostat.

Answer to Question 2

Salt build-up can be prevented by bleeding off to waste 1-2 of the
recirculating water applied to the pad. This is replaced by fresh water demanded
by the float valve in the sump tank.
