Timeswitch/Programmer

Ensure that the intended model is suitable - timeswitches can only switch one circuit, e.g. heating for combination boilers whilst programmers can switch two circuits, e.g. heating and hot water. Multi-channel programmers may be able to switch three circuits or more and are normally used where a house is divided into several heating zones.

Timers and programmers should be installed in accordance with the manufacturer's fitting instructions and comply with all the appropriate regulations.

The best location is in a well-lit area where they can be easily reached, seen and adjusted as required. Accessibility is important to encourage their use to improve energy saving.

All the timer and programmer types are available either in daily (1 day), weekday/weekend (5day/2day) or weekly (7day) cycle format.
