Weishaupt WRSol 1.0 Manual page 29

Variation 34: Calorifier with internal tank for DHW with collector cascade and heating circuit support
The WRSol 2.0 determines the temperature differential
between the collector sensors (TKO or TK2) and the
reference sensor (TPU or TSU).
As soon as the temperature differential is greater than the
increase (... Diff. On ) set, the relevant solar pump
(PS or PS2) is activated.
Once the increase ( ... Diff. Off ) or the maximum
calorifier temperature has been reached the solar pump is
switched off. TSU or TPU is selected as reference sensor.
Using the three way valve for return temperature increase
(VRA) the available energy from the calorifier can be
utilised depending on the calorifier temperature (TPO) and
the heating return sensor (THR).
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.
Possible settings MFA output:
0, 1, 2, 5, 6, 7, 8, 9, 10, 11, 12
Variation 35: Storage tank cascade for DHW and heating with collector and solid fuel boiler
• Three way valve
• Energy yield calculation (optional;
• Legionella function (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TSU, TPU).
As soon as the temperature differential is greater than the
value ( ... Diff. On ) set, the solar pump is switched on
and the storage tank is loaded.
Once the (... Temp. Setpoint value) has been
reached the three way valve switches over and loads the
calorifier provided according to the priority setting
( Ch. 7.12).
Release of solid fuel boiler pump (PFK) see Ch. 7.7.
The thermal mixer valve (TV) enables fast heat up of the
solid fuel boiler.
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.
Possible settings MFA output:
0 ... 12
