The Zodiac R06931 is a genuine replacement expansion valve card (display card A4) designed for use with Zodiac pool heating systems. This electronic control card governs the operation of the expansion valve within the heat pump circuit, playing a critical role in regulating refrigerant flow and maintaining efficient thermal exchange. As a factory-authorised spare part, it ensures full compatibility and reliable performance within the original system design.<\/p>\n
The R06931 expansion valve card is engineered specifically for integration into Zodiac pool heat pump units. The card manages the electronic signals that control the expansion valve, which is a key component in the refrigeration cycle responsible for reducing refrigerant pressure and temperature before it enters the evaporator. Correct operation of this card is essential for maintaining the heat pump’s coefficient of performance (COP) and overall heating efficiency. As a direct OEM replacement, it is designed to slot into the existing mounting and wiring configuration of supported Zodiac heat pump models, minimising installation complexity for qualified technicians. This card has been referenced across multiple Zodiac product catalogues from 2020 through to 2023, confirming its continued relevance across a range of Zodiac heating equipment produced during that period.<\/p>\n
This spare part is intended for pool owners and service engineers maintaining Zodiac pool heat pump systems where the expansion valve card has failed or is showing signs of malfunction, such as inconsistent heating, refrigerant flow errors, or fault codes on the heat pump display. It is a specialist replacement component and should be installed by a qualified pool heating technician or refrigeration engineer. It is not a universal part and is only suitable for the specific Zodiac heat pump models it was designed for. If you are unsure of compatibility, consult your Zodiac heat pump’s documentation or contact an authorised Zodiac service agent before ordering.<\/p>","protected":false},"excerpt":{"rendered":"
