The Robertshaw I-1284-P, Q, S & T Series Temperature Regulators are compact, self-contained and self-powered, three-way control valves especially adaptable to control of water and lubricating oil temperatures on internal combustion engines. The POWER PILL® element, located inside the poppet assembly, responds to the temperature of the medium surrounding it and provides the force necessary to position the poppet as the temperature of the liquid passing through the valve changes. Temperature regulation is achieved by the proportional action of the three-way valve which varies the amount of medium through or bypassing the cooler to maintain the desired temperature. Operation of the POWER PILL elements is unaffected by pressure changes in the system.

The POWER PILLS are factory-set for the specified control temperature and are not manually adjustable. By exchange of POWER PILL elements, the operating temperature may be changed in a very simple manner. Since all internal parts lift out with the valve bonnet, it is not necessary to remove the valve from the piping. The I-1284 series is equipped with a quick-acting manual operator which permits overriding the thermal element if and when abnormal load conditions are encountered in the system. 

Operation: With low temperature liquid surrounding the POWER PILL, the poppet is in the upward position which connects ports "E" and "B." As the temperature increases, the POWER PILL stem extends forcing the poppet downward. When the temperature reaches the control point of the regulator, the valve will be at mid-stroke. If the temperature continues to increase, the poppet will continue to move downward until the by-pass port (B) is completely closed off. 

On the Robertshaw I-1284 a manual crank is provided to override POWER PILL control. Turning the crank counterclockwise moves the poppet upward to close the "C" port. The "B" port may be closed by turning the crank clockwise. In event of power pill failure, the crank should be turned clockwise until the desired cooling is achieved. 

The Robertshaw I-1284 may be installed indoors or out, provided the liquid to be controlled does not freeze. Temperature regulators should be installed as near as possible to the unit being controlled, and a pipeline strainer should be installed upstream.
