Replacing timer for boiler

[jak68]

Hi,

I am looking for some advice, we have a Potterton Performa 30 HE boiler and I am looking to replace the timer that was installed with it with a more up to date digital one. The old timer is a wireless type but is there a certain type I will have to buy?

why do u want to replace?

No, a something like a Drayton 700/701 or a Honeywell CMT927 will do it.

Do you know electrics well enough? Should be straight forward if you have some knowledge on wiring the receiver. Follow the Manufacturers instructions. I am not suggesting that you should go in to the boiler and start touching stuff though. It may save you time and stress if you get someone in.
Where are you from? Look on here for a local member and talk to them.

I just want to update from the old mechanical timer we have, so we have a bit more control over the heating.:smile5:

get a honeywell 7 day programmable wireless thermostat , and do get a local heating engineer to install for you

 

[jak68]

so will any type of wireless thermostat work on any type of boiler ?

 

[SafeGasInstall]

Yes and No

 

[jak68]

:disappointed:

Yes and No

Call a local heating engineer and tell him what boiler you have , what you are not happy with and what you will be happy to have and he will then make you a few suggestions . And then all you have to do is make a decision 🙂

No. Although there is a wide range of choices that will work, there are a couple of potential pitfalls.

1) Some are made to physically fit to the front of certain boilers. They would probably work with anything in an electronic sense, but couldn't easily be physically mounted.

2) Most Performa 30 HEs were combis, and we are all assuming that this is what you have. However, there was also a Performa 30HE system boiler, whose controls would require a different set up.

I'm also a bit confused about what you have now. In post #1 you say its wireless. In post #4 you mention a mechanical timer. Do you mean its wireless in the sense that it plugs into the boiler fascia, or wireless in the sense that there is already a wireless (RF) thermostat connected to it?

Why not talk to your gas engineer when the boiler has its annual service?

 

[jak68]

there is a wireless RF connected to it, by mechanical I meant the thermostat is not of the digital type and the existing thermostat is a clock with on/off switches round the circumference

this is what you need :
CM907 7 Day Programmable Thermostat - Honeywell UK Heating Controls
