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? Many thanks

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.

Very pleased quick response and delivery
I ordered four TRV's and required a next day delivery, which I paid for and had qualified to get. They should have been delivered before 6.30pm next day. I had hoped not to be the last delivery of the day but waited patiently. The tracking system said it was on board, so I waited at the job hoping it was just late. It did not turn up till the day after that and It was only luck that someone was in to receive them. I reported the incident to you and was told I would be refunded "the difference" (Which has not happened yet). I am disgusted that I paid for a delivery service that I did not get I.E. "Next day service" and have to pay at all for it. To be offered "The difference" is an insult and unjust. Don't advertise "Next day service" if you can't deliver it. I appreciate this is contracted out. I hope they are suitably dealt with, but as it is you who has been paid, you get the complaint. The products (TRV's) are fine and I have no complaint with them at all. Shame about the delivery service.
Great service, fast delivery (to Ireland!) and keen prices.
