Manifold S3 Actuator

The WHS-M-S3-ACT230 actuators are used in combination with the Warmup S3 Manifolds to control the circuit valves. While operational, the actuator consumes less that 1W of power, making it the most efficient actuator in its class.

Key Benefits


360° Status indicator

The clear, blue disc on top of the actuator provides visibility at any angle and tactile indication in hard to see locations


Easy mounting

With a separate mounting collar and actuator, it is easy to screw the collar on before simply clipping the actuator in place


Energy Efficient

At just 1W operating power, this 5th generation actuator is extremely energy efficient

Helps Control Hydronic Floor Heating Circuits

The actuators are supplied ‘latched open’ so they can be easily mounted and commissioned. In this condition the indicator disc is only marginally raised, with no blue visible.
Upon completing their first full power cycle the actuator then operates in a normally closed manner, open the valve when power is supplied based on heating demand to the underfloor heating system.

For multi-zone manifold control, Warmup S3 Actuators are added to each circuit. Using less than 1W each while active, this 5th generation actuator is water resistant to class IP54, extremely reliable and environmentally friendly.

They are supplied ‘latched open’ for easy ‘click’ mounting out of the box. During operation the clear 360° indicator shows the current valve position, from its off, normally closed, position to being fully open. Providing a 100N actuating force on the valve, it prevents any unintentional flow through the valve during operation or pressure testing.
