Check of settings
1.Go to the overview
2. Select COP
3. Overviews for COP
Before the control starts, we check that all the settings are as they should
be.
The overview display will now show one line for each of the general
functions. Behind each icon there is a number of displays with the
different settings. It is all these settings that have to be checked.
In our example, we have only selected COP calculation.
The following functions can be selected:
The COP function is displayed on this page, and on the following
pages; the others are only displayed for orientation purposes.
A COP value should be as high as possible, but it can never exceed
the ideal value.
Left screen, column 5:
OK = 0 or 1. The value indicates whether the calculation is valid.
0 = invalid calculation
1 = valid calculation
The COP calculation may be invalid if there is a time delay in a
compressor change, where the temperature sensors are not able
to adjust to the correct temperature, and the subsequent calcula-
tion uses the correct reading.
If, over a period of time, there are several invalid calculations, the
system should be inspected for unstable operation.
If the compressor regulation is performed by an AK-PC 772, and
the “hot gas dump” function is activated, the COP calculation will
not be correct.
