User Manual
The figure 5.4 above illustrates 3 cases. Case (1) illustrates power-up delay. In case (2); the time elapses before PV rises
above the SP. The compressor is thus switched ON as soon as the PV rises above the SP. In case (3); the PV rises above the
SP while the time delay is still in progress. The compressor is switched ON as soon as the delay time elapses.
Table 5.2 lists various parameters required for setting-up appropriate compressor switching strategy and associated
parameters.
For parameter description the user is requested to read the preceding section.
