The 59T and 66T series temperature controls from Sensience (Formerly Therm-O-Disc, Sub of Emerson Electric Co.) are designed to meet the high electrical capacity requirements of electric water heaters. Both use a temperature sensitive bimetal disc to deliver snap-action to the contacts. The speed and force of contact separation provides long-dependable control life at high electrical loads. Therm-O-Disc 59T66T thermostat combines thermostat temperature controlling and temperature limiting.
