A huge amount of energy is used to heat homes. Much of it is either wasted or used inefficiently. Heating controls help to reduce waste reduce demand and use fuel more sparingly.
Honeywell has been manufacturing heating controls for over 100 years and is the UK leader for quality, efficiency and reliability.
This book contains wiring advice to assist with installing Honeywell heating controls in a variety of systems. Always try to upgrade a system to the best efficiency. This would normally be a fully pumped system with a high efficiency boiler using S, Y or S Plan Plus controls.
All wiring should be carried out by a competent installer or electrician
