IO Hvac Controls ZP3-HPS Control Panel

The iO HVAC Controls ZP3-HPS is a versatile 3-zone heat pump zone control panel designed for high-performance residential and light commercial forced-air applications. This contractor-friendly zoning solution is compatible with single-stage heat pumps, multi-stage heat pumps, and dual fuel systems, supporting up to three stages of heating and two stages of cooling (3H/2C). The panel features auto changeover logic with first call priority and a 20-minute time share function, ensuring balanced temperate control even during opposing calls. Integrated short cycle protection and an electronic discharge air temperature sensor terminal provide essential equipment safety by monitoring plenum temperatures and preventing coil freeze-ups or high-limit trips. The aluminum backplate construction includes LED status indication for simplified troubleshooting in the field, making it a reliable choice for managing 2-wire or 3-wire zone dampers in complex HVAC zoning systems.

• Universal Compatibility: Works seamlessly with specialized heat pump and dual fuel applications.
• Advanced Logic: Features first call priority with time share to manage conflicting zone calls efficiently.
• Equipment Protection: Includes a dedicated short cycle protection timer and an electronic discharge air sensor to safeguard system longevity.
• Flexible Damper Control: Successfully manages 2-wire or 3-wire dampers with an independent fan control option for every zone.
• Simplified Installation: Heavy-duty aluminum backplate and clear LED status indication streamline the mounting and wiring process.

Is the ZP3-HPS compatible with dual fuel systems?
Yes, this panel is specifically engineered to handle fossil fuel applications alongside heat pump control, allowing for seamless transitions between heat sources.

What kind of dampers can I use with this panel?
The iO HVAC Controls ZP3-HPS is compatible with most standard 2-wire (power close/spring return) or 3-wire (power open/power close) zone dampers.

Does this panel require a dedicated transformer?
Yes, a separate 24VAC transformer is required. The VA rating should be calculated based on the total number of zone dampers and thermostats in the system.
