Drayton LP722 Thermostat Details
The Drayton LP722 is sold as a thermostat, but it is really the top model of the Lifestyle programmer range. It is a 7-day dual channel programmer that switches central heating and hot water on and off separately. You can give each day of the week its own timings, which helps when the house is occupied at different times on different days. Drayton says this kind of control can noticeably reduce energy costs.
The programmer comes with a factory-set standard program. On weekdays both channels run from 6.30am to 8.30am and from 4.30pm to 10.30pm. At weekends they run from 7.00am to 9.00am and from 4.00pm to 11.00pm. The second period, ON2 and OFF2, starts and ends at 12.00pm, so it does nothing until you change it. To go back to these factory times at any point, press SET and + together.
To program the unit, use the SET?, YES/- and + buttons under the bottom flap. The display walks you through the steps: set all weekdays, then optionally adjust single days, then set the weekend. Central heating comes first, then hot water. A short press of the buttons changes the time in 1-minute steps, and holding them down changes it in 10-minute steps. If you press nothing for two minutes, the unit goes back to normal operation.
Timings must be entered in order, from ON1 through to OFF3. If they get out of order, the display flashes a warning. ON1 cannot be the last timing before midnight. OFF3 can fall after midnight, as long as it is no more than 23 hours 59 minutes after ON1. A built-in TEST? function runs through the whole week's program. At each switching point it stops and turns on the matching lights and circuits so you can check them.
Each channel has its own Advance/Boost button for quick changes. Advance moves the channel on to its next ON or OFF period, and it only works in TIMED or ONCE mode. Pressing and holding Boost adds one, two or three hours, shown as BST on the screen. Each channel also has a SELECT button to choose OFF, TIMED, ONCE or ON. Changing the mode does not affect your saved timings.
Holiday mode switches the system off for a set number of days and turns it back on in time for your return. The unit counts each pass through midnight as one day. For example, if you leave on Saturday morning and want heat again on Tuesday morning, set 3 days. The clock is set at the factory and changes for British Summer Time automatically. The weekday is worked out from the date, so if the day shown is wrong, reset the date.
Installation must be done by a qualified electrician or heating engineer. A link on the back of the unit sets the system type: P for fully pumped systems or G for gravity-fed hot water. The LP722 uses an industry-standard wall plate and the same terminal layout as many other programmers, so it can often replace an older unit without rewiring. The installation instructions include wiring diagrams for gravity, mid-position valve and two-valve systems.
