## What is Heating Wiring?

Heating control wiring, terminal by terminal, for UK electricians and heating engineers.

Pick the system or the receiver on the wall and see every terminal: what it does, where each wire goes and what colour it is. Tap a terminal on the strip to jump to it, or show one part at a time, such as just the hot water valve.

- S plan and Y plan on a wiring centre, open to everyone
- C plan, S plan plus with three zones, and combi boilers on a 230 V switched live or on relay contacts only
- Pump overrun boilers: the terminals that change are marked
- Receiver and programmer terminals for Honeywell Home, Hive, Google Nest, Drayton, Danfoss and Salus models
- A step-by-step fault-finder for each system
- Commissioning checklists you can tick off on the job
- A job sheet with customer, system, checks and notes, exported as an A4 PDF
