Instructions for setting the on/off timers for central heating systems
Each central heating system will have a programmer or time switch that will turn the heating and hot water on and off automatically at the times you decide. You can set it to suit your lifestyle and you save money because it gives you heat only when you want it. The operation of the programmer will depend on the type of heating system and model of programmer. See the list below for instructions.
