If I specify a water heating time from 17:30-24:00, it then periodically causes the heating in the radiators to drop. Therefore, I would like the water heating timings to be adjusted to my requirements -and of course to economise. Back to the original question: If the uniStor 310 is...

Looking at the following documentation, Vaillant seems to be inconsistantly stating the heating times of the uniStor cyclinders: See page 6: http://www.vaillant.co.uk/stepone2/data/downloads/c9/42/00/uniSTOR.pdf See page 4...

Excellent, looks like we're making progress here. I've set the following and so far after 3 hours of the heating switched on, the on/off cycling hasn't occurred once: - 52*C HW - 55*C CH - 3.0*C Heating Curve - 37kW Boiler Rating However, despite the continuous heating, the bottom...

I will try setting the heat curve to 2.6; however, is it really required to turn bith CH and HW dials to 100% ? I'm happy with 55*C HW.

Heating Curve is set to the default factory setting of 1.2 degrees celsius. How do I override the weather compensation and modulation settings? I would much rather prefer a situation where I can control how hot it gets and then manually switch it off when as I feel like. House is larger...
