Weishaupt WRSol 1.0 Manual page 31

Variation 38: Storage tank cascade for DHW and heating support with collector and solid fuel boiler
• Three way valve
• Heating return temperature increase
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).
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).
Release of solid fuel boiler pump (PFK) ( 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, 1, 2, 5, 6, 7, 8, 9, 10, 11, 12
Variation 40: Calorifier for heating with collector and solid fuel boiler
• Energy yield calculation (optional;
The WRSol 2.0 determines the temperature differential
between the calorifier sensor (TKO) and the reference
sensor (TPU).
As soon as the temperature differential is greater than the
value set ( Calorifier Diff. On ), the solar pump is
switched on and the storage tank is topped up until the
switch off condition ( Calorifier Temp. Off ) or the
maximum calorifier temperature has been reached.
Release of solid fuel boiler pump (PFK) ( Ch. 7.7).
Switch over three way valve (VUP) ( Ch. 7.22)
The thermal mixer valve (TV) enables fast heat up of the
solid fuel boiler.
The external heat exchanger can be blocked via the
potential free Multi-funct. output (MFA).
Possible settings MFA output:
0, 5, 6, 7, 8, 9, 10, 11, 12
