Connecting charge
pumps in the case of
multiple heat pumps
GENERAL
This function allows control of up to two extra charge
pumps (GP12). AXC 30 is required for the charge pump
for slave - EB10X, with address 3 or higher. Up to eight
slaves can be combined in one system.
AA25-EB10X-GP12.X corresponds to AA25-EB103-
GP12.3, AA25-EB105-GP12.5 and AA25-EB107-GP12.7.
AA25-EB10Y-GP12.Y corresponds to AA25-EB104-
GP12.4, AA25-EB106-GP12.6 and AA25-EB108-GP12.8.
The control module controls the charge pumps together
with the relevant slave during heating, hot water or
cooling operation via AXC 30.
A type CPD charge pump is recommended to allow the
use of speed control, which guarantees correct delta-t
in the various operating modes during the year. AXC 30
also enables external blocking of each associated slave.
PIPE CONNECTIONS
The charge pump (GP12) is positioned in the relevant
charge circuit before joining with other charge circuits
or branching off different sub-systems via a reversing
valve.
