Crop-trol Controllers

T675F

Used to control an oil-burning, portable crop dryer.

Suitable for line-voltage, low-voltage or millivolt (Powerpile) switching.

Mounts directly on dryer with sensing bulb in discharge air duct.

Knob extends through case for manual control

point adjustment.

Differential setting wheel, located under cover, adjusts difference between cut-in and cut-out temperatures.

Generic remote bulb controllers

T675, T678

Regulate temperature of air or liquids in ducts, pipes, tanks and boilers.

Suitable for applications requiring temperature control of air or liquids where controller must be placed outside the sensing area.

Typical uses include control of dampers and valves in heating, cooling and heating-cooling systems.

Fast response models (available for use in return air duct) operate approximately four times faster than standard models.

Controller can be mounted in any position.

Ambient temperature compensation provides good temperature control.
