Allowing different programmes for weekdays and weekends, and independent timing of each channel. * Warranty: 18 Months Drayton LP522 5/2 Day Programmer. Drayton LP522 programmer is our intermediate programmer which offers separate timings for heating and hot water. It has a 5 days to 2 days programme option which allows you to set different on and off periods for weekdays and weekends which suit your lifestyle patterns. You can set up to three separate heating and hot water periods per day. The advance boost button can be used to give you 1, 2 or 3 hours of heating and hot water in advance of your set time periods and this saves you from having to re-programme if you unexpectedly require a one-off burst of heating or hot water. Take control of your home's heating and hot water to keep bills down.
