Floor-heating control
Use on compatible manifold valves for room-by-room or zone-based hydronic floor-heating control.
A compact electric thermal actuator for floor-heating manifolds, radiator valves and hydronic HVAC control.
The TELIn TL55 is a thermal actuator designed to open or close compatible hydronic valves in response to a heating-control signal. The product family is available in 2/4-wire configurations, NC/NO switch options and 230V/24V versions for different project requirements.

TL55 is designed for common hydronic heating applications where a compact electric actuator is used to control compatible valves. The actuator can be considered for floor-heating manifolds, radiator systems and hydronic HVAC assemblies, subject to valve compatibility and the selected electrical version.

Use on compatible manifold valves for room-by-room or zone-based hydronic floor-heating control.

A compact actuator format for compatible hydronic radiator valve assemblies.

Suitable for selected commercial or residential hydronic HVAC assemblies after compatibility review.
Confirm the selected voltage, wiring, switch type, relay rating, valve thread and actuator travel with TELIn before ordering or installation.
The TL55 should be specified together with the compatible valve, electrical control output and installation environment. Select the correct 230V or 24V version, wiring arrangement and NC/NO configuration for the project.
The application images show representative installation contexts. Final suitability depends on the valve, wiring diagram, load and local installation requirements.


TL55 can be considered for floor-heating manifolds, radiator valves and other compatible hydronic control assemblies. Review the valve interface and electrical specifications before final selection.
Tell us the valve type, voltage, wiring, switch configuration, relay requirement, application and required quantity. TELIn can help confirm the appropriate TL55 version.
