heat pump.
1.
Move to Expert level,
2.
Select Input/output test
3.
Select row Relay output QX5, accept with button
4.
Next select Output UX 1/4 control row 7710 (Output

5.
Set the source pump's desired rotation speed on the
row. (50-100%)
6.
Ensure the pump's operation by feeling the pump, re-
ducing the shut-off valve of the collector (pipe makes
a sound), and by checking the temperatures of the
collector. The temperatures should settle between 0-
7°C.

row. (50-100%)
4.
Ensure the pump's operation by feeling the pump, re-
ducing the shut-off valve of the charging circuit (pipe
makes a sound), and by checking the temperatures of
the charging circuit. The temperatures should have
settled at the heating network's temperatures.
5.
End the charging pump's test by setting to control
