Confirm the selected voltage, wiring, switch type, relay rating, valve thread and actuator travel with TELIn before ordering or installation.

INSTALLATION CONFIGURATION

Match the actuator to the valve and control system.

The TL48 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.

  • 01 Confirm the valve interface and mechanical compatibility
  • 02 Select 230V or 24V according to the control circuit
  • 03 Select 2-wire or 4-wire version as required
  • 04 Select NC or NO switching configuration
  • 05 Confirm the 5A or 15A relay requirement before production

The application images show representative installation contexts. Final suitability depends on the valve, wiring diagram, load and local installation requirements.

APPLICATIONS

One actuator platform for common heating applications.

TL48 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.
