This is the genuine Fluidra A2 display control board (PCB) for Zodiac Z300 and related pool heat pump models. It carries the LCD user interface that allows owners and technicians to monitor and adjust pool temperature settings, operating modes, and system status directly on the unit. Without a functioning display board, the heat pump cannot be operated or configured.<\/p>\n
This board is designed for the Zodiac Z300 TD8 and is also confirmed to fit the PM30, PM30 R\u00e9versible, PowerForce 25, PowerForce 35, PowerForce Three-Phase, PowerFirst Premium, and PowerFirst Premium Defrost heat pumps. Always cross-reference your model number before ordering. Note that WTC03939D is the current revision, superseding the earlier WTC03939 reference and replacing WTC03961.<\/p>\n
As an original Fluidra spare part, this board is manufactured to the exact electrical and firmware specification of your heat pump. Third-party alternatives may carry incompatible firmware or connector layouts, risking further damage to the unit. A genuine replacement restores full functionality \u2014 including digital temperature display, mode selection, and fault diagnostics \u2014 with no compromises.<\/p>\n
Replacement of a heat pump control board involves working inside mains-voltage electrical equipment and should be carried out by a qualified HVAC or pool heating technician. Ensure the unit is fully isolated from the power supply before opening the casing. Refer to the Z300 service documentation for connector routing and board mounting details.<\/p>","protected":false},"excerpt":{"rendered":"
