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 indicates a low brine flow and a low difference indicates a
high brine flow.
Check that the correct program ("Proportional pressure")
is set on the brine pump (GP2). Only the LED for "Proportional pressure" should light around the program selector.
If it must be reset press the program selector repeatedly
until the correct LED lights (see illustration).
Set the speed of the brine pump by pressing the “Increase” or "Reduce" button. Hold the "Increase" button
to set "Max" speed.
