ference between these two temperatures should
be 2—5 °C when the system has come into bal-
ance. Adjust the flow with the knob on the brine
pump (35). A high difference indicates a low brine

between these two temperatures, with floating
condensing, should be 5 - 10 °C when the house
is being heated without additional heat. Adjust the
flow with the knob on the heating medium pump
(16). A high difference could depend on a low heat
medium flow. A low difference indicates a high
heat medium flow.
