Hi,
I have a 7 year old Viessmann WB2B combi. I noticed last night when I went to bed that the boiler was still on when it would normally be off at this time. The boiler remained on throughout the night.
There are no fault codes but the tap symbol remains on all the time, we have no heating but...
Our installer just said that our current thermostat would be ok.
Don't you need an external sensor if you don't use a CM927 or open therm thermostat if you want compensation?
The boiler and thermostat is for my Dad. I don't think he has ever touched it :) It's a CM900 and works well/does what he needs. I think that Intouch maybe a bit too much info in his situation.
Do we keep the CM900 and add an external sensor or do we change the thermostat to a CMS927.... Any...
What is different about the new stat?
Incomfort as it is called in NL has some poor reviews on Google play and on websites selling the kit. Frequent reports of all settings being lost...
Hi,
The Intergas manual talks about the Honeywell CMS927 thermostat. I can only see the CM927 on the Honeywell UK site, what's the difference between them?
Thanks
Hi,
Does anyone know how to adjust the start and end time for this calendar time switch. The time and dates are correct but it could do with switching the lights on about half an hour earlier and switching off half an hour later than it currently does.
Thanks
