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.

Did what they said they would in a quick manner - first class service. Recommended!!!
The item was delivered at the time stated and was exactly as descibed on the web site. great service.
Service very quick,received the part in France within a few days,tracking number supplied immediately sale was realised.Price for shipping was reasonable too,not a rip off like some companies.If there is a downside,I had to communicate via e-mails as there was no phone number which for some people (me included) is a bit of a pain as I am not too internet savvy.however,would definitely use them again.
