Variation 56: Energy storage tank WES and heating support
• Energy yield calculation (optional;
➭
Ch. 7.10)
• Circulation function (optional;
➭
Ch. 7.15)
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TSO or TSU). If a collector flow sensor (TKV) is
fitted this is included in the control.
As soon as the temperature differential is greater than the
value set (
Tank Diff. On
), the solar pump is switched
on and the storage tank is topped up until the switch off
condition (
Tank Diff. Off ) or the maximum storage
tank temperature has been reached.
WES function (
➭
Ch. 7.23)
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, 7, 8, 9, 10, 11, 12

WES function (

Ch. 7.23)
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
