Io Hvac Controls ZPA-SPS Static Pressure Sensor

Product Description

The IO HVAC CONTROLS ZPA-SPS is a static pressure sensor designed for use in HVAC zoning systems that require accurate duct static pressure monitoring. It measures static pressure in the range of 0.08 to 1.2 inches water column (WC), providing the feedback signal needed to maintain balanced airflow across zoned ductwork. The sensor is a compact unit measuring 4.25 inches wide by 4.25 inches tall by 5.75 inches deep and weighs 0.55 pounds. Licensed HVAC technicians install this sensor as part of zone pressure control systems to protect equipment and maintain designed airflow conditions.

The ZPA-SPS is suited for residential and light commercial HVAC zoning applications where duct static pressure must be monitored and controlled. It is typically installed in the supply duct to feed pressure readings back to a zone control panel or bypass damper controller. This sensor supports systems where variable air volume or multi-zone damper arrangements create fluctuating static pressure conditions that require continuous sensing and response.

Key Features

• Static pressure sensing range of 0.08 to 1.2 inches WC for residential and light commercial zoning
• Compact enclosure at 4.25 x 4.25 x 5.75 inches for flexible duct or panel mounting
• Lightweight at 0.55 pounds for easy single-technician installation
• Designed to integrate with HVAC zone control panels and bypass damper systems
• Delivers continuous pressure feedback to maintain balanced duct static pressure

Compatibility

Designed as an OEM-style replacement or upgrade sensor for HVAC zoning control systems requiring static pressure input in the 0.08 to 1.2 inches WC range.

Installation Notes

Installation of the ZPA-SPS should be performed by a licensed HVAC technician. Disconnect power to the air handler and zone control panel before wiring or mounting the sensor. The sensor is typically field-mounted to supply ductwork using a sensing probe fitting, with signal wiring run back to the zone controller per the manufacturer wiring diagram. Follow all applicable mechanical and electrical codes during installation.
