the 127750 is technically identical to the PTS4

Constructed to withstand the rigorous thermal cycles of modern cooling systems

this Type 1 electrolytic start capacitor is designed to remain in the circuit for a fraction of a second until the potential relay or thermistor disconnects it

you must verify the part number on your existing board as thermal requirements and connector pinouts vary by BTU rating and stage configuration

which is essential for the negative regulation gas valves found in Summit series boilers

Dwyer Instruments 2301 Pressure Gage L99H008 the 127750 is technically identicalThe Dwyer Instruments 2301 Magnehelic Gauge is the professional standard for monitoring low differential pressure in commercial and industrial HVAC systems. Featuring a . 5 0 . 5" w. c. zero center range, this analog gauge utilizes a frictionless Magnehelic movement to provide high accuracy readings without the risk of fluid evaporation or freezing common in traditional manometers. Engineered for air and non combustible gases, the 4" diameter dial
