Solar pump stations
NA28237
278-279 series
Function
Solar pump stations are used on the primary
circuit of solar thermal water heating systems to
control the temperature of the hot water storage.
The pump inside the unit is activated by the signal
from a differential temperature controller. The unit
contains the functional and safety devices for
optimum circuit control. They are available with
both supply and return connection or with return
connection only.
The iSolar
™
PLUS temperature differential controller
(optional) is suitable for management and control
of 10 pre-configured solar thermal system
arrangements installed in an optional insulation
jacket that mounts to the top of the pump station
for a nice clean assembly and simplified wiring
(code 278011).
