Schneider Electric AG14A02A on Off Actuator High Temp 24V

Product Description

The Schneider Electric AG14A02A is a two-position, normally closed, on/off actuator designed for high-temperature hydronic and zone control applications. Operating on 24 volts AC, this actuator opens and closes zone valves in response to low-voltage control signals from thermostats or zone controllers. It includes an auxiliary switch that provides end-of-travel feedback to connected equipment such as circulators or air handlers. The metal construction supports reliable performance in demanding mechanical room environments. Licensed HVAC technicians and plumbers typically install this actuator as part of zoned hot water heating systems.

This actuator is suited for residential and light commercial hydronic heating systems where high-temperature water is distributed through zone valves. It is commonly installed on Erie-style valve bodies in baseboard hot water or radiant floor heating configurations. The normally closed fail-safe position ensures the valve closes if power is interrupted, helping protect the system in the event of a control failure. Its auxiliary switch makes it appropriate for applications requiring end-of-stroke interlock wiring to pumps or air handlers.

Key Features

• Two-position, normally closed operation for fail-safe zone control
• Rated for 24 volts AC control input, compatible with standard low-voltage thermostats and zone panels
• Built-in auxiliary switch for end-of-travel interlock to circulators or air handlers
• High-temperature rating suitable for hot water hydronic heating systems
• Metal construction for durability in mechanical room environments

Compatibility

Designed as an OEM-style replacement actuator for two-position zone valve applications in residential and light commercial hydronic heating systems.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber familiar with low-voltage hydronic control wiring. Disconnect and lock out all electrical power and shut off the hydronic system before servicing or replacing the actuator. Wire the 24-volt control circuit in accordance with the thermostat or zone control manufacturer's wiring diagram and applicable local codes. Do not operate the actuator outside its rated voltage range.
