The LP111 is Drayton's basic timeswitch for combination boilers. It controls your heating and hot water together. The LP111 has a 24 hour programme setting which means you can set daily ‘on’ and ‘off’ periods for your heating. Within the 24 hour period you can set up to three heating periods. The advance heating boost button can be used to give you 1, 2 or 3 hours of heating in advance of you set time periods – this saves you having to reprogramme your timeswitch if you require a one off burst of heating. The LP111 is a simple control that suits people with regular lifestyle patterns. If you have a more varied lifestyle the LP711 may be more appropriate. Drayton LP111 24hr Electronic Timeswitch
