This is the genuine Fluidra replacement inlet water temperature sensor for the Z650iQ MD8 pool heat pump. Mounted at the water inlet of the heat pump, it continuously monitors the temperature of pool water entering the unit and relays that data to the control board to regulate heating output accurately. A faulty or degraded sensor can trigger error codes and disrupt the heat pump’s intelligent, inverter-driven operation.<\/p>\n
This sensor is specifically designed for the Fluidra Z650iQ MD8 heat pump \u2014 a full-inverter, connected residential pool heat pump sold under the Zodiac brand. Always verify your model designation before ordering, as other Z650iQ variants (MD10, TD8, TD10, TD12) may use different sensors.<\/p>\n
The Z650iQ relies on precise real-time temperature data to self-regulate across its multiple operating modes (Boost, Smart, Ecosilence, Smart+). An OEM-spec sensor ensures the resistance curve and connector match the original control board exactly, preventing erroneous readings or diagnostic faults. Non-genuine substitutes can cause persistent E07 water-inlet sensor error codes or inaccurate temperature control.<\/p>\n
Replacing the inlet water temperature sensor requires isolating the heat pump from both power and water flow before accessing the water manifold. The sensor connects to the main control board via a dedicated wiring harness. Professional installation by a qualified pool technician or heat pump engineer is strongly recommended to ensure correct seating, sealing, and system re-commissioning.<\/p>","protected":false},"excerpt":{"rendered":"
