■
One heat pump is the "master", the other is the
"slave"
■
The master heat pump may be equipped with a
changeover valve for DHW heating
■
During DHW heating, the slave heat pump can
charge the heating water buffer cylinder; alternatively
both can charge this cylinder simultaneously
■
Like the master heat pump, the slave heat pump can
serve up to 3 heating circuits. Consequently a cas-
cade facilitates up to 6 heating circuits
