Rated 5 out of 5 by Ridiculously easy to install. Bought it to replace my old one as one of the buttons got stuck due to age. Installation is super easy. It fits into the same back wall panel so you never need to touch any wires at all. No need for electrician it is SO easy. Simply unscrew your old box which has two screws at the bottom. The old box slips off the bracket, slip the new one on and that's it! Programming is simple and straightforward... The 'Holiday' setting is an extra bonus where you can turn your HW and CH off for X days while on holiday before it automatically clicks back in 6 Feb 2016

Answer: 
The LP 522 would be a functional replacement for the Switchmaster 400. However, the existing back-plate will require changing and there are some alterations to the existing wiring. The wires in terminals 1 and 4 on the existing back-plate will need to be reversed.

Whatever colour wire you have in terminal 1 on the existing back-plate will need to be connected to terminal 4 on the LP back-plate. whatever colour you have in terminal 4 on the existing back-plate will need to be connected to terminal 1 on the LP back-plate. All other terminations remain the same.

Answer: 
The LP522 is a replacement for the Horstmann Diadem. It replaces the functionality of the Horstmann programmer.The wiring however will be different and the LP back-plate will need to be used. A qualified heating engineer should be sought to change over this unit.

Answer: 
If the Drayton Tempus 7 has a slider at the bottom of it then the LP522 can be used as a direct replacement. It will fit onto the existing back plate without the need for any wiring.

If the Drayton Tempus 7 has buttons only then the back plate will need to be changed

Answer: 
The LP522 is a 5 day /2 day programmer. This allows for Mon to Friday to be programmed as a block with different times available for the weekend. It cannot be used to programme individual days. For individual day programming the LP722 must be used.
