In the example in
, the pump duty point is changed
from (1) to (2) because of a changed system charac-
teristic (thermostatic valves are closed) and conse-
quently a lower water demand.
8. Technical data

Liquid temperature: +2°C to +110°C.
Pumps in domestic hot-water systems: Continuously:
+15°C to +60°C.
To avoid condensation in the terminal box and the
stator, the pumped liquid temperature must always
be higher than the ambient temperature. See table.
