Pump capacity diagrams, collector side
To set the correct flow in the brine system the correct
speed must be set for the brine pump.
The flow must have a temperature difference between
brine out (BT11) and brine in (BT10) of 2 - 5 °C when the
system is balanced (suitably 5 minutes after compressor
start). Check these temperatures in menu 3.1 "service
info" and adjust the brine pump (GP2) speed until the
temperature difference is achieved. A high difference in-
dicates a low brine flow and a low difference indicates a
high brine flow.
Read off what speed the brine pump should have from
the diagrams below.
