Description
The Danfoss 088H3114 TWA-A is a 24V thermal actuator engineered for reliable zone valve control in hydronic heating and cooling systems. Featuring a 4-wire configuration with an integrated auxiliary switch, this actuator delivers accurate, energy-efficient flow regulation across residential and light commercial zoning applications.
Key Features
- Model TWA-A thermal actuator designed for hydronic zone valve applications
- 24V operating voltage for compatibility with standard low-voltage control systems
- 4-wire design supports both power and auxiliary switch signal wiring
- Integrated auxiliary switch provides end-of-travel feedback to boilers, chillers, or zone controllers
- Normally closed (NC) operation — opens on call for heat or cooling, closes on loss of power for fail-safe performance
- Quiet, slow-opening thermal actuation minimizes water hammer and system noise
- Compact form factor for easy installation in tight mechanical spaces
- Compatible with Danfoss zone valve bodies for a complete, matched hydronic zoning solution
Typical Applications
- Residential and light commercial hydronic heating systems
- Radiant floor heating zone control
- Baseboard and fan coil unit zoning
- Multi-zone boiler systems requiring end-switch feedback
Why Choose Danfoss TWA-A Actuators?
Danfoss is a globally recognized leader in hydronic controls and thermal actuation. The TWA-A series is built to exacting standards, ensuring long service life, dependable operation, and seamless integration with Danfoss valve bodies. The auxiliary switch output allows the actuator to directly signal a boiler or pump to energize only when a zone is actively calling — improving system efficiency and reducing unnecessary equipment run time.
