About the Weishaupt solar controller WRSol 2.0
2
The Weishaupt solar controller (WRSol) allows
easy control of your solar system.
Some characteristics of the WRSol:
•
Easy interrogation of
information
about the solar
system.
•
Temperature setpoint defaults
for DHW, frost
protection, calorifier, valve activation, legionella
and circulation.
•
Easy
reset
to previously set values or to factory
settings.
•
Recording possible with WRSol recording software.
•
Speed controlled solar and/or solid fuel boiler pump.
The WRSol can be used as differential controller for:
•
Solar DHW storage tank
•
Solar calorifier storage tank
•
Return temperature maintenance
•
Swimming pool
•
Solid fuel
•
Storage tank cascade
•
Collector cascade
•
Charge reversal of two storage tanks
•
Single layer function WES 900-C
Easy operation
Three levels
are available to you:
•
The
standard display,
in which up to three selected
values can be displayed.
•
The
selection menu level
, for the selection of one of
seven menus from where the sub-menu level can be
accessed.
•
The
sub-menu level,
where settings for additional
solar, return temperature increase, swimming pool and
solid fuel functions can be set.
2.1 What does the solar controller do
If programmed correctly, the controller, in conjunction with
the relevant hydraulic switching, will ensure that the
solar energy available is used correctly and that the need
for additional heat exchangers is largely avoided.
General operation of the system is possible once the
available hydraulic variation (system type) has been
entered. The parameters, control and safety function
relevant for the system type selected are preset
automatically. This allow immediate operation.
With the potential free contact (MFA output terminals 5
and 6) a fault can be reset, and a burner interlock
(exchanger interlock) or a request (exchanger release) can
be initiated.
Note:
On system variation 20 the potential free
contact (MFA output) acts only as fault
output.
Setting on
Multi funct. output
:
9 or 10.
2.2 What you have to observe
Do not switch off the controller
Switching off the controller can damage the
solar system, if the system is filled with water.
(Frost protection no longer guaranteed).
The controller should only be shut down for
the duration of service and repair work.
Note:
These operating instructions are valid
only
for
solar controller type WRSol 2.0
(see name plate).
