Ai Summerside born American solar water heater tank thermostat 89T13 apply constant heat step can other brands

"Therm-O-Disc" thermal disc manufactured 89T13 series temperature controller is mainly used in electric water heater at high power load environment, it has an extremely long service life. The combined thermostat to a temperature controller and temperature limiting control by combining into a thin and compact camera case. All switches are used inside Instantaneous temperature-sensitive bimetal, reliable performance, can provide high-speed contact separation, and has an extremely long service life. Features: 1, automatic reset thermostat temperature adjustment range is higher than 60 ° F (33 ° C), the lowest calibration temperature 90 ° F (32 ° C), the highest calibration temperature 140 ° F (60 ° C) . 2, manual reset thermostat temperature using factory calibration settings can not be adjusted, the calibration temperature range of 160 ° F (71 ° C) to 220 ° F (104 ° C). 3,89T series thermostat, install sheet can extend into the customer's mounting bracket, so that the thermostat is fixed to the surface of the tank. As a result of the same specifications, so 89T series thermostat installed with thermal disc of 59T / 66T series thermostat using the same mounting bracket. Switch Configuration: SPST - automatic reset, that is, a switch controls a set of circuit, the circuit controls a group of normally closed contacts, as the temperature rises, the normally closed contacts open. Once the application reset the temperature drops to a specific temperature, the contacts will automatically reset to its normally closed state. SPDT - automatic reset, SPST basically the same as the control of a group of circuits, but the circuit controls two sets of contacts, normally closed contacts disconnect auxiliary contacts are closed, the circuit connected; normally closed contact point reset auxiliary contact is open, the circuit is disconnected. 89T series thermostat manual reset part, DPST, just limit temperature control switches can be applied. After manually pressing the reset button, contacts will not be closed immediately, and when cooled to normal operating temperature, the contacts automatically closed, the design is UL and CSA certification body called "M1- automatic tripping." Even without pressing the manual reset button, when the temperature dropped to 32 ° F at (0 ° C) or less, the manual reset thermostat will automatically close.
