The Series TSWB Digital Temperature Switch has a high and a low set
point for controlling the water temperature. The low set point can either be
manually or automatically reset. This control also has a conductivity probe
input. This input supplies12 VAC to the probe to check for low water con-
dition. There are three relay outputs which can be assigned in the field to
the high temperature set point, low temperature set point or the low water
level input. The Model TS2-K configuration key can make configuring mul-
tiple controls quick and easy.
