The Drayton TS Ultra+ is a 230V thermal actuator built to control an individual zone on a water-based underfloor heating manifold. Pairing one actuator with each manifold port and a Wiser Smart Underfloor Heating Controller unlocks room-by-room smart scheduling, app control, and voice assistant compatibility across the whole system.
As the upgraded model in the TS Ultra range, the TS Ultra+ adds a stronger 120N closing force, higher IP55 ingress protection, a higher 60°C operating temperature ceiling, a detachable plug-in cable, and a manual override feature, on top of the same fast-response mechanism, opening to 4mm within 2 minutes, and the same M30 x 1.5mm manifold thread fit as the standard TS Ultra.
⚠ Please Note: The Wiser Shop product listing states “Valve type: Normally open” for the TS Ultra+. However, the official Drayton Controls manufacturer datasheet (Installer Handbook and TS Ultra/TS Ultra+ datasheet) specifies “Valve type: Normally closed”. This page follows the manufacturer datasheet as the authoritative source. Please confirm valve behaviour against your manifold's fail-safe requirements before ordering.
ℹ Good to Know: One thermal actuator is required for each channel of your Wiser Underfloor Heating Controller — a manifold with 6 ports needs 6 actuators.
Fast-Response Opening
Opens to a 4mm stroke within just 2 minutes of receiving a call for heat, reducing lag between thermostat demand and water flow reaching the floor loop.
360° Valve Status Indication
A visual indicator ring rotates with the actuator stem, letting installers confirm at a glance whether a valve is open or closed without removing the actuator body.
Compact Manifold Fit
The M30 x 1.5mm valve connection and slim housing are designed to fit modern manifolds with 40mm valve centres, including densely packed multi-port manifolds.
Higher Ingress Protection
Rated to IP55, ahead of the standard TS Ultra's IP44, giving better resistance to dust and water ingress in manifold cabinets or plant rooms.
Manual Override
A built-in manual feature allows the valve to be manually opened for commissioning, testing, or system draining without needing electrical power to the actuator.
Detachable Plug-In Cable
A 100cm plug-in cable can be disconnected at the actuator body, simplifying replacement without rewiring the manifold junction box.

Where do I install the TS Ultra+?
It installs directly onto an existing water-based underfloor heating manifold, screwing onto the M30 x 1.5mm valve port.
What does the TS Ultra+ actuator do?
It's a thermal actuator that opens or closes an individual underfloor heating zone on the manifold in response to signals from a room thermostat, allowing each zone to be controlled independently.
How many actuators do I need?
You need one actuator per manifold port (per heating channel). A 6-port manifold requires 6 actuators to control all zones.
What's different about the TS Ultra+ compared to the standard TS Ultra?
The TS Ultra+ has a stronger 120N closing force, higher IP55 ingress protection, a higher 60°C operating temperature ceiling, a detachable plug-in cable, and a manual override feature not found on the standard TS Ultra.
Is the TS Ultra+ compatible with my underfloor heating system?
It fits most standard manifolds with an M30 x 1.5mm thread and operates on 230V AC. Always check your manifold specification before ordering.
How is the TS Ultra+ installed?
Installation involves screwing the actuator onto the manifold port and connecting it to the control wiring. A qualified installer is recommended.
