Q: Hi there,
I have a British Gas UP1 controller - is the LP241 a direct plug-in replacement ?
The issue I have is an intermittent fault. When central heating and hot water heating are timed to come on together, occasionally hot water heating does not come on. If central heating switched off, then water heating switched on manually, no problem.
Have recently had boiler/pump/valve/thermostat all replaced, but issue persists. Think it must be electrical ?
A: Yes the LP241 will plug onto the UP1 backplate.
You would really need to test the output of the programmer to be certain it was it at fault.
Q: Hi - We have an acl lifestyle lp241 (original model I believe - expiry 1997!) - Will this mkIV version be a direct swap onto the backplate (our current one uses 6 wires / pin holes) - if not it there a programmer that will fit?
A: Hi. Yes it will. A simple swap.
Q: After 20 years !! the LP241 no longer remembers the proramme settings and defaults to 12.01 after an electrical interruption. Can I replace the battery responsible for the memory ?
A: Unfortunately it is not replaceable.
Q: Hi, how do I get the programmer to pair/commision with my thermostat (danfuss) ?
A: This doesn't have wireless capability. You will have/need a separate RX receiver for the Danfoss thermostat.
Does this controller have a battery backup so that in the event of a power cut it will not lose its settings?
Yes it does.
Q: Is there a wiring Diagram included with this programmer
A: Yes it is.
Q: My Myson Apollo mechanical timer has broken. Can this unit replace it and will it be easy? Thanks
A: Yes, you will need to install it on the wall next to it and wire it into the external controls terminals on the boiler.
Q: Will this timer actually replace the British Gas EMP2 MECHANICAL timer?
A: Yes it will.
Q: Hi, I have the ACL Lifestyle LS241 controller fitted at the moment but its resetting itself. Is this controller a like for like replacement and can I use the original backplane and fit myself.
A: Yes it will plug on the existing backplate for a simple 5-minute swap.
Q: The lp241 has a 3 set period per day .I only need 2 . Can I set it to just twice a day and not 3 .
Thank you Brian .
A: Yes you can.
Q: I have a British Gas UP2 programmer, can I replace it with Drayton LP241 as I would like to have the "holiday" and boost features. If I can switch these programmers, is the change easy as regards the wiring etc?
A: Yes you can. However you would lose the ability to programme each day of the week different. You will need the LP722 if you want to keep this.
It will plug onto the existing backplate for an easy swap (no wiring).
Q: My existing timer is a Drayton Tempus Three. Will a LP241 timer plug into the existing back plate.
A: Yes it will.
Q: I have a British Gas EMP2 central heating timer that is faulty. Will the ACL Drayton (Invensys) Lifestyle LP241 Programmer (Mk 4) replace this simply on a plug-in basis. Can I fir it myself without hiring an electrician?
A: Yes it will. It's a simple 5-minute DIY job.
Q: Are there any wireless room thermostats that can be used with this controller?
A: You can wire in a receiver for most of the wireless thermostats we sell.
Q: Hi, I have a problem with my central heating. The system is controlled by an LP241 Programmer and
has a Drayton Mid Position Actuator. The actuator moves to the correct position when operated by the controller. The central heating only works when the hot water is switched on. The boiler does not fire up when only the heating is called for. The thermostat has a healthy click and can be used to control the central heating when the hot water is turned on. I think that the programmer is the most likely component to be faulty, it is quite old. Would you agree with this? My LP241 Contoller looks slightly different to the MK4 controller. It has a set of buttons under the display : Select - set - Yes- + Select. Would the MK4 be a suitable replacement and would the existing back plate be usable?
Many thanks for your advice.
A: No, it sounds more like the mircoswitch in the motorised valve has failed. The fact the motorised valve always moves to the correct position shows that the programmer and room stat are working OK.
Q: Hi,it looks like our existing timer which British Gas provided a number of years ago has gone faulty.It's an EMP2 timer made by a company called Invensys.I'm not sure when it was fitted, however the warranty ran out in 2009.It consists of 2 main parts a back plate which has the electrical wiring onto which the main units sort of slides/hooks via 6 brass pins on the back of the unit.Does this replacement simply slide into the position of the existing unit?...I wish I could send you a pic so that you could relate to which one the existing unit looks like before spending £40+..awaiting your reply, many thanks
A: Yes, this will plug onto your existing backplate for an easy swap.
Q: Hi can this replace a switch master 905 programmer ?
A: Yes it can.
Q: Hi Is it suitable for the GLOWWORM ultimate boiler.
A: Yes it is.
Q: Is this a direct replacement for the British Gas EMP2 and is it suitable for a Worcester Greenstar 24i boiler
A: Yes and yes!
Q: I noticed when the clocks changed that the actual time was 10 minutes slow.
How do I change this to the correct time?
A: Please see downloads tab for instructions.
