Vaillant 470f (2012 new model) weather compensating thermostat

[stratobuddy]

I recently had a post-April 2012 ecotec plus 831 fitted, then found that the previous room controllers would not work with the new models.

The non-weather compensating controller won't be available until about November, so I HAD to have the weather compensating controller 470f instead.

I've read all the comments about WC controllers on here, but the problems still continue.

Yesterday evening it was 15 deg outside, 18 inside, and I wanted 20 so I set this temperature on the controller.

The rads became barely luke warm (curve = 1.2) and the room temp hardly altered all night. Apparently they were all at a 32 deg flow temp, and therefore had no chance of heating up the room to 20.

Later I set the curve to a ridiculously high 4.0 (the maximum) and the rads then got warmer, but according to the curve would still only be about 45 deg.

After many hours, the room temp went up to about 19 deg, so never reached the demanded 20.

I am thinking about taking the batteries out of the outside sensor, hoping it will revert to a normal controller.

Do you think this will work? Any other ideas?

I read somewhere in this thread that you had written some instructions for this timer, how would i be able to get this as I am having trouble too[

I have a similar question to you. I have had installed a vrc470f programmer, unistor cylinder, vr61/2 control centre and vr81/2 remote room stat in zone 2. I am not entirely convinced it is all working efficiently and I would like to get your thoughts on experience of what installer level parameters should be used. I believe a member known as stratobuddy wrote a doc on this? Any ideas or where the doc can be found?

Hi, ours has started to behave better since the heating engineer set the thing to" modulation" under room temp control. to get to this you go...menu,installer level,ok.system configuration, wind down to room temp control and select modulation. i don't know why but this seems to have fixed our problem, in fact the thing seems to get hotter than required now , but at least we're not cold any more. hope this helps if not send me another message.
