Drayton Wiser Heat Switch - Connected Actuator Module (CCTFR6730)

Description

The Drayton Wiser Heat Switch (CCTFR6730) is a flush-mounted, 16A connected actuator module that switches a resistive electrical load — such as an immersion heater or electric heating circuit — under wireless control from a Wiser multi-zone heating system. It is the electrical switching component behind features like Wiser's hot water zone control.

The module fits inside a standard flush wall box and communicates with the Wiser Hub (Generation 2) over Zigbee, so it can be scheduled and controlled through the Wiser Home app alongside the rest of the heating system. Manufacturer part reference: CCTFR6730.

Please Note

This module requires a Wiser Hub Generation 2 and the Wiser Home app to operate — it is not compatible with Generation 1 hubs and cannot be used as a standalone switch without a paired Wiser system.

16A Resistive Load Switching

Rated for 16A at 230V AC resistive loads, with a maximum switching current of 14A across the 200–250V AC range — suitable for immersion heaters and similar resistive electric loads.

Wireless Zigbee Control

Connects to the Wiser Hub Generation 2 via 2.4 GHz Zigbee (2.5 mW at under 50 m range), enabling remote scheduling and control through the Wiser Home app.

Compact Flush-Mount Module

A compact 40 x 45 x 16.9 mm module that fits inside a standard flush wall box behind a faceplate, keeping the installation discreet.

Local Status Indication

A single tri-colour LED (green, amber, and red) gives at-a-glance status and pairing feedback without needing to open the app.

Screw Terminal Connections

Fitted with screw terminals rated for 1–2.5 mm² cable, with a 6.5 mm wire stripping length, for a straightforward first-fix electrical connection.

Form A Relay Output

Uses a 1 form A relay output rated 200–240V AC, 1 pole, providing simple on/off switching of the connected circuit.

Important Safety Information

This module connects directly to the 230V AC mains electrical supply and switches a mains-powered circuit. Installation, wiring, and connection must be carried out by a qualified electrician in accordance with BS 7671 (IET Wiring Regulations) and relevant UK Building Regulations (Part P). Always isolate the supply before installation.

Frequently Asked Questions

What is the Drayton Wiser Heat Switch used for?

It's a connected relay module used to switch a resistive electrical load — typically an immersion heater — under wireless control from a Wiser multi-zone heating system, allowing hot water to be scheduled and controlled through the Wiser Home app.

Does this work with the first-generation Wiser Hub?

No. This module is designed for the Wiser Hub Generation 2 only.

Can it switch inductive or motor loads?

It is rated for resistive loads only — 16A at 230V AC, 14A maximum switching current. It is not designed for inductive or capacitive loads.

Where is this module installed?

It's a flush-mount module designed to sit inside a standard wall box behind a faceplate, connected to the mains supply and the switched circuit via screw terminals.

Does it need a qualified electrician to install?

Yes. As it connects directly to the 230V mains supply, installation must be carried out by a qualified electrician in line with UK wiring regulations.
