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.

Central honeywell air conditioner


Sounds like it may have lost power. Check the breaker and the fuse at the furnace. If they are all in the on position and working then it sounds like you may need a technician. If the display is blank on the thermostat you may also want to replace the batteries.

I had the same problem. I traced it to the micro switch in the water/central heating motorised valve having shorted out.

I replaced the (Honeywell) motorised valve and it is now only running when it should.
