Hello – I currently have a Invensys SM1 Programmer which is not switching off. I understand that this means it is probably unrepairable. I have been told that the LP111 is compatible and can be easily slotted into the existing electrics. Can you confirm that this is the case?


Thank you for your enquiry - Please find product page link for the Drayton SM1 time switch which is still available https://www.uk-plumbing.com/drayton-invensys-timeswitch-sm1-24-hour-p-1282.html The Drayton LP111 (24 hour) is a direct replacement for the SM1
and the 7 day version  https://www.uk-plumbing.com/drayton-invensys-lp711-7-day-time-switch-p-1273.html Both will fit the existing backplate of the SM1.
