Can I get a digital thermostat?

[Fordy81]

Now I apologise in advance but my boiler/central heating knowledge is embarrassing.

I have a Potteron Suprima 60 HE boiler, with the mankiest programmer which looks very much like the Drayton LP112, which I will get changed for a new one.

However, is it possible to have a wireless digital thermostat with this boiler?

If not, is it possible to change my current dial thermostat with a digital version? When I take the screws out of the bottom the dial unit slides straight off. The wires remain in the wall and it connects via touch metal (sorry don't know the term for this ).

Thanks very much

Yes that is possible. However I would suggest that you keep the current programmer to control Hot Water times and buy a wireless programmable stat to control the heating.

You will get the benefits and features of a digital stat, and the flexibility of separate times for CH and HW. (The LP112 uses the same times)

Thanks for that. Could you suggest a suitable stat?

Could I get an identical programmer to replace the current one? It really is disgusting and I'm putting in a new kitchen so it's going to stick out like a sore thumb.

There's no need to splash out on a new stat. Just move the current stat to the airing cupboard, where the HW cylinder and other components are located. The number of times changes are made to the HW times are very few, so going upstairs to turn the HW on if its gone cold is not too much of an inconvenience.

The cable which currently runs from junction box in the the airing cupboard to the programmer can be disconnected at both ends and left in place.

As for which wireless programmable stat, I would recommend the Honeywell CM921 (24 hour) or CM927 (7 day)

Sorry, when you say move the stat, do you mean the programmer thing? Does that not need to be connected to the boiler? Or is there some other stat?

My apologies! I meant to say move the existing programmer.

The programmer does not connect directly to the boiler. It connects via a junction box, which is probably in the upstairs cupboard with the HW cylinder, cylinder stat, pump and motorized valve, which are also connected to the junction box.

Thank god for that. Thought I had a grasp of it and then I was completely lost. lol

Oh ok. I'll have to have a proper look in there. I know it has so stat dial on the tank and a couple of other bits in there.

About the digital stat.

How does this work? Does one unit plug in to where the old dial is, then the portable bit connects to that one?

If you're looking to change the programmer and also want a wireless room stat, consider the new Drayton Mitime RF. It's a 2 channel programmer for hw and ch, and also acts as a receiver for the wireless room stat that's included. Better to have 2 compatible units for ease of use and installation.

There are two possibilities for the relay unit:

1. If there are three wires available at the old stat (Live, Neutral and switched Live; terminals 1, 2 and 3 on a Honeywell stat), you can install the relay unit in place of the old stat.

2. If only two wires to old stat, then the best location for the relay unit is upstairs, wired directly to the junction box. The relay should be placed outside the cupboard, e.g above the door, so it is visible. The existing stat can be removed and the cable to it will be redundant - disconnect from junction box.

The portable part is not designed to be moved around from room to room, but located in a central place. The wireless feature is only there to remove the need for running long cables to the required location.

If you are happy with the location of the current stat, you might as well buy the CM907 and install it in its place.
