My ACL lifestyle lp522 doesnt turn heater off

calling a service man would be my choice .

The display should not be blank, meaning nothing there to look at. Different digital thermostats can be powered in 3 ways. Just from their battery's, from the furnace control transformer, from the furnace control transformer with battery back up in case the control power fails to retain your programming. Usually, removing it from the base and pulling the battery's to kill ALL of its power, waiting a minute or so then re-powering it, will restore the factory program and return the display. Also, there may be a small fuse on the back of the stat. If it has one, it will be easy to see if you are looking for it. Easy to miss if just looking at it for no reason. Be sure there is power to it. The battery's and their connections first. If you have a meter, check for control voltage. Put one lead on "R" then touch the other to "C", "Y" or "H". Should have 24 volts (AC) from the furnace transformer. I have never seen a stat blow from a power outage. But?

go to boiler Disconnect red line and jump out White and red line at boiler if the fires reconnect red line and replace thermostat

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.

if you can turn off the hw and ch off , to the off postion and it shuts off then the acl lifestyle could needreplacing mine did the same on ch only so changed mine , or check the divtervalve is working and not stuck in the open postion , try turning hw on and off only then the ch see if valve works

And one that is just a "climate control Lifestyle LP522", I would think it has to be one of these two, but please let me know if it isn't, here's the other one:

your zone valve or three port valve will be sticking

make sure it is not set to auto on your control... set it to heating.. this will fix your problem

the stat works using a bi metalic strip so that click you here is making a contact and telling the boiler to call for heating so if you getting no click you need a new room stat. Replace with same model and note the wiring most stats only use 2/3 wires depending on system

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?
