Electrothermal actuator 22CX230NC2 actuator series 22CX (ON/OFF) with wax element and auxiliary contact

Intelligent heating control with Watts 22CX230NC2 electrothermal actuator

This compact electrothermal actuator from Watts, designed for heating and air conditioning installations, provides precise control of the heating or cooling medium flow. The device is an ideal solution for both professional installers and end-users looking for an effective way to regulate room temperature. Thanks to its low power consumption (only 1.8W) and remote control capabilities, the 22CX230NC2 actuator is a modern approach to thermal comfort.

Product features and application

The 22CX230NC2 actuator is compatible with thermostatic valves, fan coil unit valves, and manifolds. Its versatility makes it suitable for various heating systems, including underfloor heating. It operates in ON/OFF mode, meaning it opens or closes the valve depending on the electrical signal sent by the room thermostat or controller. The NC (normally closed) model ensures safety – in the event of a power failure, the valve remains closed. This avoids uncontrolled heat flow.

• Wide application: Thermostatic valves, fan coil units, manifolds.
• Operating mode: ON/OFF – simple and efficient control.
• Safety: NC (normally closed) version – valve is normally closed when power is off.
• Low power consumption: Only 1.8W – energy saving and reduced operating costs.
• Easy installation: Standard M30 x 1.5 thread ensures compatibility with most valves on the market.

Advantages and benefits

The Watts 22CX230NC2 actuator stands out not only for its functionality but also for its durability and reliability. Made from high-quality materials, such as chrome-plated brass (threaded nut) and flame-retardant plastic (housing), it guarantees a long service life and safe use. Additionally:

• Compact design: Allows installation in limited space.
• Durability: High-quality materials ensure long-term, trouble-free operation.
• Status indicator: Transparent housing element allows for quick visual control of the actuator position (open/closed).
• Cable length: 1 meter – provides flexibility during installation.
• Protection: Protection class IP54 (in vertical position) protects against moisture and dust.
• Microswitch (4-wire version): Additional functionality enabling integration with building management systems.

The supply voltage is 230V, and the power consumption is only 1.8W. The actuator stroke is 3.5 mm, and the connection thread size is M30 x 1.5. The protection class is IP54 (in vertical position).

Construction and installation

The 22CX230NC2 actuator is characterized by a simple construction that facilitates installation and servicing. The threaded nut made of chrome-plated brass ensures a tight connection with the valve. The power cable with a length of 1 meter facilitates connection to the thermostat or controller. Installation is intuitive and does not require specialized tools – simply tighten the nut by hand (without using wrenches). It is important to maintain the correct mounting position (vertical) to ensure the appropriate IP54 protection class.

Remember: NC type actuators are de-energized closed - meaning they block the medium flow by default! This is important when planning the operation of the entire heating or cooling system!
