Ideal for HVAC professionals who supply their own sensors and transformer, the ZP3-ESP delivers the same intelligent pressure management and broad system compatibility as the full kit — in a standalone panel format.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e✓ Free shipping on this item — ships from The AC Outlet.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eFeatures \u0026amp; Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eThe ZP3-ESP continuously monitors system static pressure through a connected static pressure sensor. When pressure rises above the setpoint, the panel opens non-calling zone dampers just enough to relieve the excess — with tests showing little to no impact on zone temperatures. The result is a cleaner, more efficient zoning installation without the cost or complexity of bypass hardware.\u003c\/li\u003e\n  \u003cli\u003eCompatible with single-stage, multi-stage, heat pump, and dual fuel equipment, the ZP3-ESP supports up to 2H\/2C conventional or 3H\/2C heat pump and dual fuel configurations. A full suite of adjustable controls and easy switch configuration make it one of the most flexible and installer-friendly panels on the market. Housed in a compact ABS plastic enclosure (9.5″ H × 6.75″ W × 2.25″ D) and rated from -40°F to 150°F, it’s built to perform in any installation environment. Backed by a 10-year warranty.\u003c\/li\u003e\n  \u003cli\u003eFeatures:\u003c\/li\u003e\n  \u003cli\u003eNo Bypass Damper Required — ESP technology automatically relieves excess static pressure by modulating non-calling zone dampers, removing the need for a bypass damper entirely\u003c\/li\u003e\n  \u003cli\u003e3-Zone Universal Control — Manages up to 3 independent zones from a single panel; the smallest universal panel offered by iO HVAC Controls\u003c\/li\u003e\n  \u003cli\u003eBroad Equipment Compatibility — Supports up to 2H\/2C conventional or 3H\/2C heat pump and dual fuel systems, including single-stage and multi-stage equipment\u003c\/li\u003e\n  \u003cli\u003eAuto Changeover — Seamlessly switches between heating and cooling modes without manual intervention\u003c\/li\u003e\n  \u003cli\u003eFirst Call Priority with Time Share — Ensures the highest-priority zone is served first, with a 20-minute time share cycle to maintain balanced comfort across all zones\u003c\/li\u003e\n  \u003cli\u003e2nd Stage Capacity Control — Optimizes system efficiency by managing second-stage equipment operation based on demand\u003c\/li\u003e\n  \u003cli\u003ePurge Cycle Option — Helps clear residual conditioned air from the system for improved performance\u003c\/li\u003e\n  \u003cli\u003eAdjustable High \u0026amp; Low Limits — Customizable discharge air temperature limits to protect equipment and maintain comfort\u003c\/li\u003e\n  \u003cli\u003eAdjustable High \u0026amp; Low Balance Points — Fine-tune the crossover between heating and cooling stages for dual fuel and heat pump systems\u003c\/li\u003e\n  \u003cli\u003eEasy Switch Configuration — Intuitive selector switches simplify system setup and reduce commissioning time\u003c\/li\u003e\n  \u003cli\u003eFused-Protected Inputs \u0026amp; Outputs — Dual 3-amp fuses protect both the printed circuit board and relay contacts for added reliability\u003c\/li\u003e\n  \u003cli\u003eCompact, Durable Enclosure — ABS plastic housing with snap-on cover; mounts on snap track with 2 back plate screws (9.5″ H × 6.75″ W × 2.25″ D)\u003c\/li\u003e\n  \u003cli\u003eWide Operating Range — Rated from -40°F to 150°F for reliable performance in any installation environment\u003c\/li\u003e\n  \u003cli\u003e10-Year Warranty — Industry-leading coverage for long-term peace of mind\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eZones:\u003c\/strong\u003e 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eESP \/ Static Pressure Control:\u003c\/strong\u003e Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem Type:\u003c\/strong\u003e Conventional, Dual Fuel, Heat Pump\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStages:\u003c\/strong\u003e 3 Heat\/2 Cool\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840119931792\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions (W×H×D):\u003c\/strong\u003e 14.00\" × 14.00\" × 6.00\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Weight:\u003c\/strong\u003e 5.00 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"iO-HVAC","offers":[{"title":"Default Title","offer_id":51446075981991,"sku":"ZP3-ESP","price":362.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/0416\/4007\/files\/iO-HVAC-ZP3-ESP-01_85675a7f-556a-464b-8282-500e44dd0cf3.png?v=1790805561","url":"https:\/\/theacoutlet.com\/products\/io-hvac-controls-zp3-esp","provider":"The AC Outlet","version":"1.0","type":"link"}
