  • Page 19 FACTORY COMPRESSOR Compressor Switching Strategies The PPI “Temperature + Humidity” composite controllers offer different programmable strategies for compressor switching to meet different design approaches by the manufacturers of Humidity Chambers. The various strategies and the implementations are described here. 1. Compressor Off The compressor is kept Off.
  • Page 20 HumiTherm Plus for PC User Manual 4. PV Based Strategy In this strategy, the compressor is switched to cool down the chamber air temperature. The controller switches the compressor ON or OFF based on the comparison between the chamber temperature value and the Temperature SP.
  • Page 21 HumiTherm Plus for PC 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.
