## Summary description

Electric actuator TECH STZ120TBK with a 3-point control signal, designed for 230 V AC supply. Travel time is 120 seconds and it comes with an attached 1.5 m cable in black. Suited for HVAC damper and valve control where simple open/close or three-position control is required; provides reliable timed actuation for building ventilation and heating systems.

## Long description

The TECH STZ120TBK electric actuator is designed for three-point control of dampers and valves in HVAC systems. It operates from a 230 V AC supply and provides a travel time of 120 seconds for full stroke. The actuator is supplied with an attached 1.5 m cable and is finished in black. It is intended where simple open/close or three-position control is required and delivers timed mechanical movement suitable for ventilation and heating system installations.
Advantages
The TECH actuator offers reliable timed operation with a defined 120 s travel time, making position and synchronization planning straightforward. Its three-point input simplifies integration with basic control panels or thermostats that use open/close/stop signals. The fixed 1.5 m cable reduces installation time by avoiding separate wiring preparation, and the compact black housing fits discreetly into HVAC cabinets or on ductwork. The design prioritizes mechanical consistency and ease of mounting for routine building services applications.
Suitable for
Control of HVAC dampers for ventilation and air-handling units
Actuation of zone valves in heating systems requiring open/close or three-position control
Retrofit projects where a simple 230 V AC actuator replaces manual or older units
Applications needing timed movement with predictable travel time for coordinated system sequencing
Key specifications
Control signal: three-point (open/close/stop)
Supply voltage: 230 V AC
Travel time: 120 seconds for full stroke
Cable length: 1.5 m (attached)
Color/finish: black housing
How to use
Mount the actuator on the damper or valve following the manufacturer’s mechanical interface guidelines and ensure secure coupling to the shaft or spindle. Connect the three-point control wiring to the 230 V AC supply and control outputs, observing local electrical codes and safety practices. After power-up, verify the direction of travel by applying open and close commands and adjust linkage or stroke limits if necessary. Perform a few manual cycles and timed tests to confirm the 120 s travel and correct seating at end positions.
Usage recommendations
Use the actuator in dry indoor environments or protected enclosures; avoid exposure to direct weather without additional protection. Periodically inspect mechanical linkages and cable condition, and schedule functional checks to ensure travel time consistency and reliable three-point control response.
