Wireless room thermostat advice please

CrazyM101

Hi all,

We're about to replace our old 20 year + Potterton for a Worcester Bosch Greenstar Compact 28CDi. I've checked a lot of websites and reviews etc and decided to go for this model.

We now require a wireless room thermostat and this is where I'm having difficulties. I can't seem to find one that is consistently recommended. Are the Honeywell CMT927s better than the WB own DT10RF/DT20RF?

What features should I be looking for, and paying a bit extra for etc.

Hope someone can help.

Thank you

I can't speak for the wireless version, but I have the Honeywell wired equivalent, which I have found to be an excellent programmer. Most of the RGI's on here seem to be favourable to Honeywell too.

Honeywell are my programmer/stat of choice.

The Worcester DT10 will link exclusively to the boiler, but whether is provides any extra benefits is debatable

We have the Honeywell. Does the job its designed to do and very easy to programme.

The ability to copy a heating programme from one day to the next is well worth having. No idea if the Worcester version has this capability.

I can't comment on other models, but I'm delighted with my CM927 - which I gather is the same model as the CM927T.
I had a new boiler two and half years ago and the plumber fitted a CM927.
I love its features and I'm sure it saves me money without any loss of convenience.
Each day is split into 6 time zones which I can choose. I can then set the temperature for each zone. It took me a while to gradually home in on the best settings for my lifestyle. It allows for different settings for each day of the week, but as I'm now retired, everyday is a 'weekend' day as far as I'm concerned, so all my days have been set to the same settings.
Should ever I feel a touch hot or cold, a quick touch of the plus or minus keys adjusts the temperature - afterwards the device returns to normal when the next time zone is reached.
When I go out for the day (if I remember) I can set the temperature to a lower setting, knowing that when I return at 18:00 the house will be back on its normal setting. Alternatively, I can hit the 'Party' button and set the temperature to X degrees for the next Y hours. Similarly, when I go on holiday, I can easily hit the 'Holiday' button, and set the temperature to a lower X degrees for Y days.
In the past when I went away in Winter, if it was a holiday, I would set my thermostat to a lower protective temperature, but on my return I would have to wait for the house to come back up to my normal temperature. Now I can easily set the system to a lower temp, knowing that the house will already be back to normal on the day of my return. When I used to go away for a weekend, to avoid a cold house on my return, I used to leave the thermostat unaltered - wasting money heating the house when I was away. Now I can set a different temperature whilst I'm away, and but have the house warm for my return.
The CM927 can be wall mounted or used with a small stand. I use the latter on a shelf, as I've not got around to filling the hole in the wall used by my old thermostat and the new one wasn't going to cover it completely, as it's a different shape - so I just left the old obsolete 'stat on the wall. Using the stand does also mean it's easy to pick-up when I want to make adjustments.
My plumber said that the CM927 couldn't be set to use Centigrade, but when I eventually got around to checking the manual, I found Centigrade could be selected.
Had I known what modern controls could do, I would have ditched my primitive system earlier. I'm sure the cost of the CM927 was quickly recovered by savings made on days and weekends when I'm away.

Have you had a look at british gas remote heating controls?. Drayton wireless programmer with smartphone app for remote use.

Do you work for British Gas? Perhaps you could answer my question here.

Thanks.

Honeywell is our first choice as well.

Out of interest which Potterton boiler are you replacing?

Hi all, thanks for all the replies, it seems that the Honeywell is a firm favorite amongst not just MSE members but general public as well.

I've not looked at the British Gas options but to be honest I don't trust them so will never use their costly services!

I'm quite surprsed that the Worcester Bosch units I mentioned don't seem to be widely used/reviewed but I guess if everyone's done their homework then they would go with the most effective solution.

So off I go looking for a shiny new Honeywell thermostat!

To answer the last question, we are replacing a Potterton Netaheat 10/16 Electronic. It has never missed a beat in the 7 years we've been in this house and must be at least 20 years old! Only reason for changing it is to remove the tank in the store room and use the space for a new cloakroom!

Just to let you know, I have a Worcester 30 greenstar model and have had the DT20RF thermostat since installation 5 years ago. The unit allows timed control of hot water and heating over 2 channels and I've been pleased with it. The thermostat allows for normal control temperature as well as a simple push button overide/setback. If you're looking for a simple timer/stat with no frills, then I'd certainly recommend it.
