Product Overview

The FHK WB10 10 Zone Wiring Centre has been developed to provide a reliable, professional and cost-effective control solution for wet underfloor heating systems using 230V room thermostats and thermal actuators.

Designed with installers in mind, the WB10 centralises all electrical connections into one clearly organised enclosure, making installation faster, future maintenance simpler and fault finding significantly easier.

Supporting up to 10 independently controlled heating zones, the WB10 delivers precise room-by-room temperature control for residential and commercial underfloor heating systems.

Unlike many competing wiring centres, the Zone 10 output can be switched between an underfloor heating zone or a dedicated radiator zone, making it an excellent choice for hybrid heating systems where towel rails, radiators or extension circuits require independent control.

The integrated pump and boiler control, selectable pump delay and built-in electrical protection provide everything required for a neat, professional installation — all at outstanding value compared with many leading-brand alternatives.

Ideal Applications

• Wet underfloor heating systems
• New build developments
• Self-build projects
• Domestic renovations
• Commercial heating installations
• Multi-zone heating control systems
• Hybrid UFH and radiator systems

Key Features

• Controls up to 10 independent heating zones from one compact wiring centre.
• Compatible with most 230V wired thermostats and thermal actuators.
• Centralised wiring layout simplifies installation, servicing and troubleshooting.
• Integrated pump and boiler switching for complete system control.
• Selectable 1 or 3 minute pump/boiler delay helps reduce unnecessary cycling.
• Zone 10 radiator mode allows connection of a radiator or towel rail valve without operating the UFH pump.
• Zone 10 UFH mode enables all ten outputs to operate as standard underfloor heating zones.
• Built-in circuit protection helps safeguard connected heating controls.
• Clearly labelled terminals speed up installation and minimise wiring errors.
• Compact, robust enclosure manufactured for long-term reliability.
• Excellent value alternative to premium-brand wiring centres without compromising on functionality.

Technical Specifications

Why Choose the FHK WB10?

The FHK WB10 has been designed to offer installers everything required from a professional underfloor heating wiring centre, without paying premium-brand prices.

• Designed specifically for wet underfloor heating systems.
• Compatible with most standard 230V wired thermostats.
• Suitable for our own FHK controls as well as many leading thermostat brands.
• Simple, clearly labelled wiring layout reduces installation time.
• Provides neat, centralised wiring for faster servicing and future maintenance.
• Excellent choice for domestic and commercial installations.

Hybrid Heating Made Simple

Unlike many standard wiring centres, the FHK WB10 allows Zone 10 to operate as either an underfloor heating zone or a dedicated radiator zone.

• UFH Mode: Zone 10 operates exactly the same as Zones 1-9, controlling an actuator and activating the boiler and pump.
• Radiator Mode: Zone 10 controls a radiator valve independently without energising the underfloor heating circulation pump.

This makes the WB10 ideal for properties incorporating towel rails, radiators, extensions, loft conversions or hybrid heating systems.

Important Information

Designed for use with 230V wired thermostats and 230V thermal actuators.

Always check thermostat switching compatibility before installation.

Professional installation by a suitably qualified installer is recommended.

Please refer to the wiring diagram supplied with the unit before installation.
