Hello,
Apologies if this is a stupid question but I cannot work out how to use my new heating.
Got a Worcester Bosch 27i System boiler, Honeywell ST9400C programmer & DT92E wireless roomstat.
All works fine other than when I increase the temp on the wireless stat the heating turns on even if programmer is set to heating off. It appears to be some kind override heat on demand.
If the room temperature drops below the temp set on the roomstat the heating comes on, even if the programmer is set to heating off.
Effectively the heating is set to on continuously unless the temp exceeds the roomstat setting.
I have been all through the instructions and on the web but cannot find anything.
Am I doing something wrong here or is it wrongly installed.
Thanks
