1 Four temperature sensors PT1000 for the
connection of the storage cylinder are
supplied with the product assembly with elec-
tronic control. The number of the required sto-
rage cylinder temperature sensors depends on
the chosen hydronic system.
2 Large pipe diameters and high temperatures
may lead to gravity circulation in the storage
cylinder circuit. If necessary, the installation of
gravity restrictors in the supply pipe near the
storage cylinder is recommended.
