The iSolar WMZ-G1 is a measurement
and display unit for solar thermal sys-
tems and conventional heating systems.
It is possible to connect up to two
Grundfos Direct Sensors
. Depending
™
on the number and type of sensors
connected, the unit is capable to show
temperature values, flow rates and
relative or differential pressures or a
combination of them.
Heat quantity measurement is possible
if two Grundfos Direct Sensors
connected and at least one of them is
a VFS type sensor. The optional calo-
rimeter especially takes into account
that the density and the specific heat
capacity of the heat transfer medium
depend on the temperature as well as
on the mixing ratio of water / glycol.
Using these parameters and the mea-
surement of flow rate, flow and return
temperature, the unit calculates the
heat quantity.
A power failure protection guarantees
that the adjusted system parameters
and the calculated heat quantity are
maintained in the case of power loss.
Different sensors can be chosen and
configured using the push buttons. The
temperature of the selected measur-
ing point, the heat quantity gained, the
are
™
current power or the flow rate of the
system are indicated on the display.
A control lamp and a relay are inte-
grated to indicate sensor defects and
exceeded or underrun value ranges.
