The Partlow MF79 indicating controller is a compact single-switch temperature controller that provides on-off control for fuel valves or relays which start and stop heating or cooling systems. Twelve operating ranges are available to the Partlow MF79, covering -30°F to 1100°F.

The MF79 indicating controller can be panel or surface mounted. Brackets are supplied should you choose to wall mount the controller. Electrical hookup to the MF79 is accessible through the top cover hatch.

A single snap-acting switch is positioned at the control point by turning the setting knob on the front of the Partlow MF79 indicating controller. Setpoint is shown by the red pointer on the dial. The switch is operated by a black indicating pointer which moves up or downscale in response to the expansion or contraction of the thermal element. When the indicating pointer moves in line with the red setpointer, the snap-acting switch opens or closes the circuit controlling the heating or cooling input to the Partlow MF79.

The Partlow MF79 indicating controller is UL and CSA listed.
