Weishaupt WRSol 1.0 Manual page 21

Variation 17: Calorifer with internal tank for DHW
• Energy yield calculation (optional;
• Circulation function with sensor (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TPU or TSU). If a collector flow sensor (TKV) is fit-
ted this can be included in the control.
As soon as the temperature differential at the reference
sensor is greater than the value set ( ... Diff. On ), the
solar pump is switched on and the tank is topped up until
the switch off condition ( ... Diff. Off ) or the
maximum calorifer temperature has been reached. TSU or
TPU are selected as reference sensor.
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 18: Calorifier with internal tank for DHW with collector bypass
• Energy yield calculation (optional;
• Circulation function with sensor (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TPU or TSU). If a collector flow sensor (TKV) is
fitted this can be included in the control.
As soon as the temperature differential at the reference
sensor is greater than the value set ( ... Diff. On ), the
solar pump is switched on and the tank is topped up until
the switch off condition ( ... Diff. Off ) or the
maximum calorifer temperature has been reached. TSU or
TPU are selected as reference sensor.
The three way valve (VBY) is switched over depending on
the collector temperature (TKO) and the reference
sensor (TBY).
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
