IO Hvac Controls ZP2-HC-ESP-KIT Control Kit

The iO HVAC Controls ZP2-HC-ESP-KIT is a 2-zone single-stage zone control panel kit engineered for residential and light commercial forced-air systems. This HVAC zoning system features integrated ESP static pressure control, which electronically monitors system static in real-time. By modulating closed dampers to a partially open position when pressure exceeds the setpoint, the ZP2-HC-ESP removes the need for a traditional bypass damper. This design effectively prevents evaporator coil freeze-ups and eliminates excess air noise, ensuring optimized airflow throughout the ductwork. The kit includes a ZPA-SPS static pressure sensor, a discharge air temperature sensor for high/low limit protection, and a 40VA transformer. It supports auto changeover with first-call priority and is compatible with both 2-wire and 3-wire zone dampers. With independent fan control per zone and adjustable short-cycle protection, this kit provides a streamlined solution for 1H/1C applications without requiring complex mechanical pressure relief.

Key Benefits

• Integrated ESP Technology: Built-in static pressure monitoring eliminates the cost and labor of installing a bypass damper.
• System Protection: Includes a duct temperature sensor to provide high/low limit protection, preventing equipment damage.
• Contractor-Friendly Setup: Simplified wiring for 2-zone 1H/1C systems with clear LED status diagnostics for all calls and damper positions.
• Improved Comfort: Eliminates the "whistling" duct noise common in smaller zones by bleeding excess pressure into non-calling areas.
• Universal Damper Support: Works seamlessly with standard 3-wire MD dampers or 2-wire spring-return actuators.

Common Questions Does this kit require a bypass damper? No. The ESP (Electronic Static Pressure) logic manages excess pressure by modulating non-calling dampers, making a mechanical bypass damper unnecessary in most 2-zone standard applications. What thermostats are compatible with the ZP2-HC-ESP? The panel accepts any standard single-stage heat/cool thermostat, including programmable, non-programmable, and manual or auto changeover models. How does the "Time Share" feature work? If there are opposing calls (heating and cooling), the system uses First Call Priority. If the calling zone is not satisfied within 20 minutes, the panel will automatically change over to satisfy the opposite demand.
