2-Wire 230V Thermal Actuator: Normally Closed, Snaps On (video guide)

The 2-wire 230V thermal actuator from MaxHeatUFH sits on an underfloor heating manifold valve and opens that circuit when the room thermostat calls for heat. It is normally closed, snaps on and works in any position.

Watch the short video below, and download the data sheet and install manual for the exact specification.

Key facts

• 230V AC supply, 2W running power
• Normally closed, so it shuts when the power is cut
• 3.0mm stroke, 100N force
• IP54 with a 1m cable
• Snaps on and works in any position
• One actuator per circuit

How to fit it

1. Use one actuator per circuit, even for two loops in one room
2. Take the cap off the valve and snap the actuator on
3. Label the cable with the room
4. A qualified electrician connects the two cores to a 230V wiring centre
5. Call for heat in each room. The indicator shows open after a few minutes
6. If a circuit won't open, check the supply at the wiring centre first
