SETTING OF COMPRESSOR DELAY TIME
The delay time of low stage side compressor can be set to reduce the load on the power line and to
facilitate the start-up (reset) of the freezer after power failure.
The example in the table is based on the assumption that the delay time is changed to 4 minutes. The
delay time is set to 1 minutes at the factory.
Note:
■
The setting range for delay time is between 1 and 15 minutes. The cool down of chamber temperature
may be slow when the setting of delay time is over 5 minutes, depending on the installation environment.
There is no need of changing the delay time when the capacity of power source is enough.
