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.
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.
