Energy yield calculation (optional;
➭
Ch. 7.10)
The WRSol 2.0 determines the temperature differential
between the collector 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.
The three way valve (VBY) is switched over depending on
the collector temperature (TKO) and the reference sensor
(TBY).
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).
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
Variation 41: Calorifier for heating with collector/bypass and solid fuel boiler

As soon as the temperature differential is greater than the
value set (

), 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.
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).
