Dwyer Instruments  offers the Series TSWB digital temperature switches designed with high and low set points for controlling the water temperature and checking water level.

The low set point can be manually or automatically reset, with the control also featuring a conductivity probe input that supplies 12 VAC to the conductivity probe to check for low water condition.

Three relay outputs can be assigned in the field to the high temperature set point, low temperature set point or the low water level input.

Series TSWB digital temperature switches also come with the Model TS2-K configuration key to simplify the configuration of multiple controls.
