Thermostatic actuator TSA 12, M30 x 1.5 mm, 230 V AC, NC 79066

Thermoelectric actuators – automation in heating and cooling systems

The TSA 12 thermoelectric actuator is a reliable device designed for automatic flow control in heating and cooling installations. Mounted on shut-off valves, especially in return beams of manifolds, it enables precise opening and closing of circuits based on a control signal from a strip or thermostat. Its design and parameters make it an ideal solution for both professional installers and end-users looking for comfort and energy efficiency.

Construction and application

The TSA 12 actuator operates in a normally closed (NC) mode, which means the valve is closed by default. It only opens when 230 V AC voltage is applied. It has a built-in mechanical position indicator that allows for visual control of the operating status – a yellow color indicates an open valve. The stroke length is 4 mm, and the pressing force of 110 N ensures reliable and effective operation. Made of durable plastic, the actuator is characterized by high resistance to corrosion and mechanical damage. The length of the connection cable is 1 meter, which facilitates integration with the existing installation.

Functionality and benefits

• Automation: Enables remote control of the flow of heating or cooling medium, increasing comfort and reducing energy costs.
• Precision: Ensures accurate opening and closing of valves, which translates to optimal operation of the heating or cooling system.
• Status indicator: The built-in indicator allows for quick visual control of the actuator status without the need to intervene in the installation.
• Solid construction: Made of plastic guarantees durability and resistance to environmental conditions (IP54 protection class).
• Easy installation: M30 x 1.5 thread enables simple and quick mounting on standard valves.
• Manual operation: Available manual operation function allows for emergency control of the actuator in case of power failure or automation problems.
• Voltage-free feedback: Provides information about the current valve status to the control system.
• Two-point control signal: Enables easy integration with various building automation systems.

The additional FIRST OPEN function ensures correct valve setting during the first system start-up. The operating ambient temperature is from 0 to 50°C, which allows the actuator to be used in a wide range of operating conditions. Using the TSA 12 actuator translates to increased energy efficiency of the building and improved comfort of using the heating or cooling system.
