What it is

The LP522 MK4 is an electronic programmer from Drayton Controls, supplied under product code 25475. It is a heating and hot water time control unit built around a 5/2 day programming format with 2 on/off periods. It sits within the clocks, timers and programmers category of boiler controls, where it handles the switching schedule for the system rather than any combustion or hydraulic function.

Before you order

  • Check the model and product code on the existing programmer so the replacement matches what is being removed.
  • Confirm the 5/2 day format and the number of on/off periods suits the property's heating and hot water schedule.
  • Check the fixing and wiring arrangement of the unit being replaced before starting the swap.
  • Note the existing switching times and settings so the new schedule can be set up without guesswork.
