14. When the power is supplied (without battery)
Compressor H: Compressor H turns on with 2minutes (initial value) of delay after the
power was supplied. Compressor H runs with regardless of PV.
Compressor L:
In PV䋾SV (when the cascade sensor temperature is -34.1㷄 or lower),
compressor L turns on with 2minutes (initial value) of delay after the
power was supplied.
In PV䋾SV (when the cascade sensor temperature is -34.0㷄 or higher),
compressor L turns on with 2minutes (initial value) of delay after the
power was supplied and cascade temperature is reached at -34.1㷄.
*Note) Delay time of both compressor H and L cannot be set individually.
Setting data: The setting data initialized in F17 is retrieved in non-volatile memory.
