This Hydraulic-Action temperature control is readily ap- plicable for many types of commercial or industrial heat- ing applications.

The speed of response of the temperature sensitive element makes it particularly applicable to warehouses, factories, garages and similar installations.

PRECAUTIONS

THESE CONTROLS MUST BE INSTALLED BY A QUALIFIED INSTALLER.

Do not exceed the specification ratings.

All wiring must conform to local and national electrical codes and ordinances.

This control is a precision instrument, and should be handled carefully. Rough handling or distorting compo- nents could cause the control to malfunction.

This control has been accurately calibrated at the factory. Any attempt to calibrate this control will void the White- Rodgers warranty.

ELECTRICAL DATA

THERMAL DATA

Switch Action: S.P.S.T. - Open on Rise

Range: 20° to 90°F (-7°to 32°C)

 

Differential: 3° to 20°F (1.7° to 11°C) Adj.

When the temperature in the controlled area rises, the fluid in the coiled element expands, causing the contacts in the switch mechanism to snap open, turning off the heating system.

PRINCIPLE OF OPERATION

As the air cools in the controlled area, the fluid in the coiled element contracts. When the temperature drops to the control setting, the contacts snap closed turning on the heating system.
