Notes:
1. The example is just for applicaon illustraon; please confirm the exact installaon method according to the installaon manual.
Modularity is perfect when an extension of capacity becomes required as the building cooling/heang demand evolves. 6
units can be controlled in group. The group control system can control and view the operaon of the enre system only by
connecng the master to the wire controller. If the DHW funcon is required, the water tank can only be connected to the
master unit water circuit through a three-way valve, and controlled by the master unit. If AHS is needed, it c
an only be
connected to the master waterway and controlled by the master unit. The Tbt1 temperature sensor must be installed in
the parallel system (otherwise unit cannot be started). If the balance tank is too large, Tbt2 needs to be added in order to
improve the control accuracy. Tbt2 is set in the lower part of the balance tank. The water inlet and outlet pipe joints of
each unit of the parallel system should be connected with so c
on
necons and one-way valves must be installed at the
water outlet pipe.
