System PACi and PAW-VP380L
Room heating (and cooling)
system with multiple outdoor
units and 380L tanks,
controlled via outdoor unit
This system solution has no limitations on capacity or functionality. To increase capacity, in-
crease the number of PAW-VP380L tanks.
The system solution can be used for heating and cooling.
Remember to always install pressure balancing valve for outlet water for equal water flow. Water
circulation can be increased or decreased for the desired temperature difference between turn
and return water flow.
One controller PAW-VP-RTC5B-PAC for each tank is needed when using PACi.
