providing a high filtering area that prevents premature plugging

Designed for long-term field service

By installing this device directly into the regulator vent

the EP-321 features a 0-20 PSIG output range and a sophisticated pulse train mechanism that allows any triac or contact closure to drive pneumatic damper actuators and valves with extreme accuracy

Precision Thermal Calibration: Factory-set 150°F open and 130°F close differentials prevent heat exchanger fatigue and ensure consistent safety cycling

Robertshaw 790-500 Module R-410A providing a high filtering areaMaintain precise combustion control with the Robertshaw 790 500 RAM 5, a dedicated 24V intermittent pilot ignition module engineered for high demand residential and commercial heating equipment. This intermittent pilot control effectively manages the ignition sequence by initiating the spark and pilot valve simultaneously upon a call for heat. Field technicians rely on the RAM 5 for its ability to provide continuous pilot flame monitoring at a
