Menu item „ 2nd Buffer HC3/4“
In general:
For so-called "micro-net installations", a second buffer can be installed in an adjacent building from
which the consumers installed there (heating circuits, domestic hot water circuits) can get their heat. In
this case, the heat is transported vie a feed pump and underground heating pipe from the first buffer
(at boiler) to the second buffer.
Temp. top:
Shows the actual temperature at the top of the buffer.
Charge:
Shows how many % of the buffer are "loaded".
Temp. bot:
Shows the actual temperature at the bottom of the buffer.
Temp.1stBuff.top:
Shows the actual temperature at the top of the first buffer (at boiler).
Pump:
On = feed pump running, Off = feed pump standing still;
The pump is switched on if heat is demanded by the "consumers"
connected to the buffer, e.g. heating circuit 3/4 or Dom.Water 2 and the
temperature at te top of the first buffer is higher than the temperature at
the top of the second one.
