Is the buttons still working, eg, boost, on/off etc? or is the heating not working?

If so the LCD/Control panel may have lost power, this usually a switch/or fuse that may have been accidently powered of or blown

    is there a trip fuse in your fuseboard that may have tripped, is anything else, sockets etc not working?



    is the a fuse connected to the unit?

    check your mains fuse box to see if anything is tripped. Is there a fuse beside the timer?

How do i set the heating/hot water timer on the LP112-24 acl controler ?


The instructions are available here: http://www.draytoncontrols.co.uk/Complete_LP_Installation_User_Instructions.aspx I hope I have been of help but please do not hesitate to ask if you have any further questions. Set the central heating Press the YES button, and the display will ask 'SET CH PROG?'. Press YES and you'll see ON1, the start of your first central heating period. Adjust it in 1-minute steps using the - and + buttons. If the - and + buttons are held down, the time changes in 10-minute steps. Press SET?, and you'll see OFF1, the end of your first central heating period. Adjust this in the same way, press SET?, then repeat the procedure for ON2, OFF2, ON3 and OFF3. Set the hot water When you press SET? after setting OFF3 for the central heating, the display will ask 'SET HW PROG?'. Press YES, then set your times in the same way. Remember, in this mode you can have different times to your central heating if you wish. When you press SET? after setting OFF3 for the hot water, the programmer will return to normal operation.

Hi you never mentioned which programmer the LP522 replaced, as the LP522 is a 5/2 day programmer.

you may of wired directly to the heating on terminal on the programmer?

It may of been that you had a basic programmer which was only designed for the system you have installed.If i know what existing programmer was used i may be able to help?
