Weishaupt WRSol 1.0 Manual page 17

Variation 9: Storage tank cascade for DHW and heating support via three way valve
• Heating return temperature increase
• Three way valve
• Circulation function without sensor (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference sen-
sor (TSU, TPU). If a collector flow sensor (TKV) is
fitted this can be included into the control.
As soon as the temperature differential is greater than the
value set ( ... Diff. On ), the solar pump is switched on
and the tank is loaded. Once the (... Temp. Setpoint) is
reached, the three way valve changes over and loads the
calorifier provided, in accordance with the priority
setting ( Ch. 7.12).
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.
With the three way valve used for return temperature
increase (VRA) the energy available from the calorifier can
be used depending on the calorifier temperature (TPO) and
the heating return sensor (THR).
Possible settings MFA output:
0, 1, 2, 5, 6, 7, 8, 9, 10, 11, 12
Variation 10: Storage tank cascade for DHW, heating support via three way valve and retrieval function
• Heating return temperature increase
• Three way valve
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TSU, TPU). If a collector supply sensor (TKV) is
fitted this can be included into the control.
As soon as the temperature differential is greater than the
value set ( ... Diff. On ), the solar pump is switched on
and the tank is loaded. Once the (... Temp. Setpoint)
is reached, the three way valve changes over and loads
the calorifier provided, in accordance with the priority
setting ( Ch. 7.12).
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.
With the three way valve used for return temperature
increase (VRA) the energy available from the calorifier can
be used depending on the calorifier temperature (TPO)
and the heating return sensor (THR). Using the charge
reversal pump calorifier-tank (PPS) the energy stored is
transferred depending on the calorifier temperature (TPO)
and the storage tank temperature (TSO) ( Ch. 7.19).
Possible settings MFA output:
0, 1, 2, 5, 6, 7, 8, 9, 10, 11, 12
