Watts Manifold Actuator – Zone Control for Underfloor Heating Manifolds

Watts Manifold Actuators are designed to control water flow to individual zones or rooms in your underfloor heating system by opening or closing the relevant ports on the manifold.

These compact actuators are fully compatible with all our manifolds and thermostats, making them the perfect solution when you want individual zone control for improved comfort and energy efficiency.

Ideal for use with multi-zone underfloor heating systems, the actuator allows your thermostat to signal the manifold when heating is required in a specific area, opening or closing the valve accordingly.

Key Features:

• Zone-by-Zone Water Flow Control
• Compatible with All Our Manifolds & Thermostats
• Automatic On/Off Response via Thermostat Signal
• Compact & Reliable Design
• Low Power Consumption
• Simple Clip-On Installation

Frequently Asked Questions

• What does a manifold actuator do?

It opens or closes the flow of warm water to each underfloor heating zone, based on signals from your room thermostat.

• Are these actuators compatible with your manifolds?

Yes – they're fully compatible with all of our manifolds and UFH thermostats.

• How are they controlled?

Each actuator is controlled by a room thermostat, which tells it when to open or close the water supply for that specific zone.

• Do I need one actuator per room?

Yes – you’ll need one actuator per loop/zone that you want to control independently.
