• Pressure actuated high limit, safety control for steam heating boilers, It breaks an electrical circuit to shut down the burner if steam pressure rises above a safe level
• Contains an SPST Micro switch snap-acting switch
• Sensitive pressure actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
• A screw on top of the case allows setpoint adjustment without removing the cover
• Differential is adjusted by means of a dial located inside the case
• Recommended minimum setpoint is differential setting plus 1-1/2 psi
• Stainless steel diaphragm sensor element
• Makes at setpoint on pressure fall breaks at setpoint plus differential on pressure rise

• Remote bulb thermostats 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
• Refer to T775 Electronic Remote Temperature Controller where more exact control is required and/or remote controller location is preferred
• T675A Models: fixed differential have an electrical rating of 125VA at 120/208/240VAC and 277VAC
• T675B Models: 125VA pilot duty up to 277VAC
• T678 Models: maximum connected load of 2,000VA
• Frequency: 50/60Hz
• Dimensions: 5-5/8"H x 2"W x 2-5/8"D
