PAuto Panel
P-Series panels are primary panels designed to supply down-stream panels with boiler water, which will in turn distribute boiler water to the radiant or other hydronic heating zones. They also remove air and provide essential service and monitoring capabilities.
The PAuto Panel is the same as the PMan Panel, but includes the Watts 9-11S M3 backflow preventer/auto boiler fill valve. This assembly also functions as a pressure-regulating, dual check-valve backflow preventer with atmospheric vent. The panel is plumbed in 1.25' L copper and equipped with Watts quickconnect unions to quick coupling to other HydroNex panels.
All P Panels come pre-wired with a 9' power supply cord and measure 28" wide x 31.5" tall x 12" deep (S).

Standard equipment includes:

  • High performance micro-bubble air remover
  • Primary loop pump of your choice
  • Watts isolation pump flange
  • Service valves
  • 0-50psi/60-320F gauge
  • White, powder-coated steel enclosure

Every P Panel comes with a pre-wired switching control. It turns on the P Panel's primary pump and closes a dry contact for the boiler Aquastat upon a call for heat from any source. The panel comes with a 9' power supply cord for quick and easy field installation.
