A4.1.5 PREWASH MODULE
The PREWASH MODULE family parameters are selected and edited by using the keys in the same way as
that described for the USER SETTINGS family.
The PREWASH MODULE family contains the parameters that identify the prewash module characteristics.

This function is enabled only if the heat pump is
installed and allows maintaining the CU
