Take the guesswork out of multi-zone HVAC installation with the iO HVAC Controls ZP3-HCMS-ESP-KIT — a complete, ready-to-install 3-zone control solution for multi-stage heating and cooling systems in residential and light commercial applications. This all-in-one kit bundles everything you need into a single part number, so there’s no hunting for compatible accessories or worrying about mismatched components.
What’s Included:
- ZP3-HCMS-ESP 3-Zone Multi-Stage Heat/Cool Zone Control Panel
- Static Pressure Sensor
- Discharge Air Temperature Sensor
- 40VA Transformer
No Bypass Damper. No Extra Parts. No Hassle.
The ZP3-HCMS-ESP-KIT features iO’s award-winning ESP (Electronic Static Pressure) technology, which continuously monitors duct static pressure as zone dampers open and close. When pressure exceeds the setpoint, the panel automatically signals non-calling zone dampers to open — maintaining proper system pressure without the cost or complexity of a conventional bypass damper.
Features:
- Built-in static pressure control eliminates the need for a bypass damper
- Designed for multi-stage heating and cooling systems
- Auto changeover for seamless heating and cooling transitions
- First call priority with time share ensures balanced comfort across all zones
- Independent fan control by zone for precise comfort management
- LED status indication for fast, easy diagnostics
- Short cycle protection extends equipment life
- Adjustable high limit discharge air control (130°F–160°F) with preset low limit (45°F)
- Compatible with 2 or 3-wire zone dampers (3-wire iO dampers required for full ESP functionality)
- Aluminum enclosure with snap-on cover for a clean, professional installation
- Mounts easily on snap track with two back plate screws
