Viessmann BW 351.A07 Installation And Service Instructions For Contractors Download Page 16

Page: 16 / 148

With water/water heat pump conversion kit, incl. one common
primary pump

Note
If the first and second stage heat pumps
(type BW and type BWS) are installed
with different rated heating outputs, 2 pri-
mary pumps are required due to the dif-
ferent flow rates.
