Hej!
Jag hittade precis detta eminenta forum och skulle vilja be om lite råd.
Jag kan läsa danska utan problem, men vad föredrar ni att jag skriver, svenska eller engelska?
I have a Blackstar 1016 that has been running fine for a year. It is setup like following:
The boiler is connected to a well insulated ackumulator tank of 750 litres with coils for hot water and solar heating.
A 3-way thermostatic valve makes sure the return flow to the boiler is always above 55 degrees
The radiators are connected to the ackumulator tank with a 4-way shunt VRB140 that prioritizes solar heat from the bottom of the tank and only takes "expensive" pellet heat from the top when it is needed.
I have mounted a temp sensor near the top of the tank connected to T5.
In the V10 control I have activated "External stop temperature 80" and "External stop difference 25"
This works great. In the summer the tank stores enough hot water for several days, in the mean time the boiler is cool and I have no heat losses to the chimney or basement at all.
When the tank is empty of heat, the boiler starts and runs for several hours until it is again full of 80 degrees water.
Now to the problem, I have connected a motorized valve for the radiator shunt and am letting the V10 control regulate this with "vejr kompensation".
I have sensors as following:
T5: ackumulator tank
T6: radiator flow temperature
T7: outside temperature
In the weather compensation page I cannot select T7, only T5. I cannot use T5 for outside temperature since this is used for measuring the tank.
Unfortunately in my location the internet weather data is very inaccurate, and often 5 degrees out.
The strange thing is, on
http://stokercloud.dk/dev/showmain.php?mac=skogslund at the bottom right it shows my outside temperature, but it says "T5" even though it is read from T7.
If you look at the graphs, please note there are some air pockets in the system which means the readout power is fluctuating a little.
Any ideas how to change this so I can use the external sensor for weather compensation?
