1.12 CIRCULATION UNIT.
The pump unit allows to connect the storage tank
to the solar collector, making the water circulate
according to the request of the control unit.
Two types of circulation units are present, single
coupled flat collectors (CP4XL) and double cou-
pled vacuum collectors (CSV14).
