4.2 Connection of electronically regulated circulating pumps

Electronically regulated circulating pumps have high starting
currents, which may shorten the service life of the heat pump
manager. For this reason, a coupling relay is installed or must be
installed between the output of the heat pump manager and the
electronically regulated circulating pump. This is not necessary if
the permissible operating current of 2 A and a maximum starting
current of 12 A are not exceeded in the electronically regulated
circulating pump or if express approval has been issued by the
pump manufacturer.

NOTE
Two or three connection cables must be laid between Econ5 

NOTE
The high-efficiency brine packages and the high-efficiency pumps (UPH)
are supplied with the relevant coupling relay for connecting and
operating the electronically regulated circulating pump.
ATTENTION!
It is not permitted to connect more than one electronically regulated
circulating pump via a relay output.
