David,
thanks a lot. I´ll have a look.
Could you please help me in another case. My plan is to connect the HP
to a storage tank and then giving a temperature from the storage (type4)
to my type56... How can I realize that my type 56 can be heated to
achieve a constant room temperature of e.g. 20°C ?!
Someone told me that I must use HEATING and then INPUT... but what if i
would like to simulate a simple radiator with a simple inlet temperature
of e.g. 55°C.
Do you understand my problem? I dont know how to cover my heat demand
out of the storage.
Thanks in advance
Best,
Michael
