THERM-O-DISC 58T-Series Adjustable Thermostats

Description

THERM-O-DISC Adjustable Thermostats *8T Series

The *8T line of adjustable temperature controls from Therm-O-Disc is designed for applications requiring accurate calibration tolerances and narrow temperature differential. The bimetal disc design of the *8T provides instantaneous "snap-action"�contact operation, which offers excellent reliability under heavy electrical load conditions - **7VAC, *5 amps resistive and *0 amps inductive.

Typical Applications
Typical applications include electric baseboard heaters, room air conditioners, commercial dishwasher,portable and built-in electric heaters and attic ventilator fans.

Switch Actions
The *8T cycling contacts are single pole, single throw (SPST). They can be provided to open on temperature rise and close on temperature fall, as required for electric heat applications; or to close on temperature rise and open on temperature fall, as required for ventilator fans or room air conditioners.
The *8T is available with auxiliary mechanically operated contacts to provide either a double pole break in the "off" position for electric heat applications or a "fan on only" feature.

Thermal Characteristics
Calibration - The *8T can be calibrated at any temperature from *0�F (*1�C) to **0�F (*5.5�C). Our preferred calibration tolerance is �3�F (�1.7�C), with a �2�F (�1.1�C) tolerance available when required.

Differential - The differential is the difference between the nominal open and close temperatures. Preferred differentials are 5�F (3�C), 6�F (3.5�C) or 7�F (4�C) with a �2�F (�1.1�C) tolerance. A 4�F (�2.8�C) differential is also available with a �2�F (�1.1�C) tolerance.

Range - The range is the difference between the thermostat operating temperatures measured at extremes of the set positions of the adjusting stem - full clockwise vs. full counterclockwise. Preferred ranges for the *8T are *0�F (*7�C), *5�F (*5�C), *0�F (*3�C) and *0�F (*0�C).

The *8T series from Therm-O-Disc is both UL and CSA recognized.
