Johnson Controls P-3800-1 Controller Refrigerant ensuring the thermocouple/thermopile and pilot

ensuring the thermocouple/thermopile and pilot flame interact correctly with the safety magnet

preventing hunting and improving system efficiency

Optimized Heat Transfer: Ensures the entire evaporator surface is utilized for cooling by maintaining a consistent saturation level

which is more common for natural gas pilot loads or specific low-pressure specialized burners

Johnson Controls P-3800-1 Controller Refrigerant ensuring the thermocouple/thermopile and pilotThe Johnson Controls P 3800 1 Reset Volume Controller is a high performance, pressure independent submaster device engineered to regulate airflow within Variable Air Volume (VAV) systems. Designed for precision, this pneumatic airflow controller operates with a supply pressure range of 13 25 PSIG and delivers an output pressure of less than 2 PSIG. It is built to maintain a constant reset span, which effectively eliminates hunting and ensures stable
