Give supply to the main control box.
Turn the "Mode" switch to the "Cool" or "Heat" position.
Check that both pumps have an even flow.
As the compressor runs, the fresh water temperature will begin to
cool down (if the unit is in "Cool" mode) or to heat up (if the unit is in
"Heat" mode). As the fresh water temperature is approaching the set
point ("Cool" mode = +12° C, "Heat" mode = +40° C) the thermostat
will stop the compressor.
The speed at which the water cools down depends from several fac-
tors, as the number and capacity of fan coil connected, the fan coil
speed, the room temperature, etc….; therefore this value is not a
valuable parameter.
