15.4 Testing inputs and outputs
Here we assist on how you can test the operations of devices
connected to the controller. The input/output test suspends all the
controller's normal control operations. Turn off the compressor
before starting the test, by switching the F1 motor protection to
OFF position.
In order to carry out the input/output test, you must be in Expert
level.
COLLECTOR PUMP TEST
Collector pump test is carried out on user terminal 1 of the lead-
ing 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
test UX1)
5.
Set the collector 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.
7.
End the collector pump's test by setting row 7710 ---
and switch off relay test (No test).
CHARGING PUMP TEST
Each compressor module has a charging pump. Test must be car-
ried out for each charging pump separately.
1.
Select Input/output test in menu Output UX 2/4
2.
Select control row 7716 (Output test UX2)
3.
Set the charging pump's desired rotation speed on the
row. (50-100%)
4.
Ensure the pump's operation by feeling the pump, re-
ducing the shut-off valve of the charging circuit (pipe
52
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
row 7716 ---.
CHANGE-OVER VALVE TEST
Change-over valve test is carried out on user terminal 1 of the
leading heat pump.
1.
Select Input/output test in menu Relay test (7700)
2.
Select to row Relay output QX8, accept with button.
The change-over valve turns to the DHW charging
position A. (red triangle points to A)
3.
Select to row Stop all. The change-over valve turns to
the heating charging position B. (red triangle points
to B)
4.
End the test by setting to control row No test.
HEATING CIRCUIT MIXING VALVE TEST
1.
Select Input/output test in menu Relay test (7700)
2.
Select to row Relay output QX10, accept with button.
The mixing valve runs open.
3.
Select to row Relay output QX11, accept with button.
The mixing valve runs closed.
4.
End the test by setting to control row No test.
MIXING HEATING CIRCUIT PUMP TEST
1.
Select Input/output test in menu Relay test (7700)
2.
Select to row Relay output QX9, accept with button.
The mixing heating circuit's pump is activated.
3.
End the test by setting to control row No test.
PUMP HEATING CIRCUIT PUMP TEST
1.
Select Input/output test in menu Relay test (7700)
2.
Select to row Relay output QX12, accept with button.
The pump heating circuit pump is activated.
3.
End the test by setting to control row No test.
HOT WATER CIRCULATING PUMP TEST
1.
Select Input/output test in menu Relay test (7700)
2.
Select to row Relay output QX13 accept with OK but-
ton. The hot water circulating pump is activated.
3.
End the test by setting to control row No test.
ELECTRIC RESISTOR CONTROLS TEST
1.
Select Input/output test in menu Relay test (7700)
2.
Select to row Relay output QX1, accept with button.
K25 resistor control is activated.
3.
Select to row Relay output QX2, accept with button.
K26 resistor control is activated.
4.
Select to row Relay output QX3, accept with button.
K6 domestic hot water resistor control is activated.
