• A single switch, non-indicating temperature controller with front panel set point.
• Twelve temperature ranges covering -30ºF to 1100ºF.
• Can be panel or surface mounted.

Overview / Design Principle:

This unit is a compact single-switch industrial temperature controller designed to operate fuel valves or relays which start and stop heating or cooling systems. It can also be used as a limit device for sounding an alarm, actuating lights or to shut down equipment at a pre-determined temperature. Compact, flush or wall mounted (brackets included), externally adjustable set point, available in twelve optional ranges within -30ºF to 1100ºF. UL and CSA listed.

Operation:

Temperature is set by turning the large, easy to handle setting knob on the front of the instrument to the desired point on 200 angular degree semi-circular scale.

Expansion and contraction in the sensing element moves the switch-actuating lever through a simple mechanical linkage. Optional weather resistance accessory (Acc 243) is available. Adaption of Acc 243 provides for inverted mounting and special gasketing for resistance to normal outdoor climate conditions.
