Weishaupt WRSol 1.0 Manual page 37

Variation 53: Storage tank sequence connection for DHW, retrieval function and legionella function
• Legionella function (optional;
• Energy yield calculation (optional;
• Circulation function (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TSU). If a collector flow sensor (TKV) is
fitted this is included in the control.
As soon as the temperature differential is greater than the
value set ( Tank Diff. On ), the solar pump is switched
on and the storage tank is topped up until the switch off
condition ( Tank Diff. Off ) or the maximum storage
tank temperature has been reached.
Depending on the average pump speed and the minimum
storage tank temperature, the external heat exchanger can
be blocked via the potential free Multi-funct. Output
(MFA).
In addition an 18 hour block can be activated.
The DHW function ( Ch. 7.14) can also influence the
MFA output.
By adding cold water the warm water from the DHW tank
is transported into the dual stratification tank.
Using the charge reversal pump-calorifier-tank (PPS) the
energy stored in the calorifier is transferred depending on
the calorifier temperature (TPO) and the storage tank
temperature (TSO).
Possible settings MFA output:
0 . . . 12
Variation 54: Energy storage tank WES
• Energy yield calculation (optional;
• Circulation function (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TSO or TSU). If a collector flow sensor (TKV) is
fitted this is included in the control.
As soon as the temperature differential is greater than the
value set ( Tank Diff. On ), the solar pump is switched
on and the storage tank is topped up until the switch off
condition ( Tank Diff. Off ) or the maximum storage
tank temperature has been reached.
WES function ( Ch. 7.23)
Depending on the average pump speed and the minimum
storage tank temperature, the external heat exchanger can
be blocked via the potential free Multi-funct. Output
(MFA).
In addition an 18 hour block can be activated.
The DHW function (Ch. 7.13) can also influence the MFA
output.
Possible settings MFA output:
0, 1, 2, 7, 8, 9, 10, 11, 12
