Calling All Solar Heating Experts
Discussion
I'm not sure if it's either simply the time of year or whether I have actually changed something on the control panel on the solar hot water heating control panel. I was messing about with the control panel a couple of weeks back, flicking through the options etc, however now we don't seem to be getting hot water through the taps, doesn't seem to actually be doing anything. Is this due to the time of year and temperature decreasing - although I'm sure it doesn't matter that much on solar panels as I thought they rely more on light than temperature.
As I look at it at the minute, the settings on the Velux control panel are:
Red Dial - 30c
Blue Dial - 25c
Pressure - around 2 bar
Col - 22.7c
tst - 35.1c
53 - 36c
n % - 0
h P set - 8022
On this panel are 4 pipes - 2 out the right hand side and 2 going from the top , all these pipes are cold to touch , and 1 of the ones going out the top , the left most one is copper and has a red box on which says solar on it - this is warm to touch but the pipes are cold.
If this means anything to anybody as it may as well be in Chinese to me? Any help would be appreciated to stop the missus moaning about the water being lukewarm or cold!

The system is a velux TFF 200 if you know it ? I haven't seen the collector temp higher than either internal tank temp recently anyway , not sure if it is during the warmest part of the day. I did notice on the side of the tank, a white plastic box , seems to be a thermostat of some sort, set at 60c, range from 30-90. This was hanging down a bit , as if it's been knocked, so could this affect it at all?

Boiler is now working , I'm wondering after having a poke around whether it could be anything to do with a blocked pipe perhaps ? Now the boiler is on there is a water pipe going into the water tank , it goes past a tap marked 'coil insulator in', then round a 90 degree left bend and 3-4 inches later round a right hand bend, however this water pipe is very hot to touch all the way up to the first bend, but then the pipe is only lukewarm on the next bend , literally 3-4 inches later , this piping then hits a junction with a big red box simply marked 'hot water'. There is a pipe below too that does the same, which has a 'coil insulator out' tap on it. Is a blocked pipe a possibility ? seems unlikely that both pipes would be blocked.
