Variation 74: Calorifier and additional calorifier with bi-directional loading and collector cascade
• Bi-directional loading ( Ch. 7.20)
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO or TK2) and the
reference sensor (TPU).
As soon as the temperature differential is greater than the
value set (Calorifier Diff. On), the relevant solar
pump is switched on and the calorifier is topped up until
the switch off condition (Calorifier Diff. Off) or the
maximum calorifer temperature has been reached.
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.
Using pump calorifier-additional calorifier (PPZ) the energy
stored is transferred to the additional calorifier depending
on the calorifier temperature top (TPO) and the additional
calorifier temperature bottom (TZU). The return loading is
carried out using pump additional calorifier-calorifier (PZP)
depending on TPO and the additional calorifier
temperature top (TZO) ( Ch. 7.20).
Possible settings MFA output:
0, 5, 6, 7, 8, 9, 10, 11, 12
Variation 76: Energy storage tank WES and additional calorifier with bi-directional loading and solid fuel boiler
• Energy yield calculation (optional;
• Bi-directional loading ( Ch. 7.20)
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 and the storage tank is topped up until the
switch off condition (Calorifier Diff, Off) or the
maximum calorifer temperature has been reached.
WES function ( Ch. 7.23)
Release of solid fuel boiler pump ( 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.
Using pump calorifier-additional calorifier (PPZ) the energy
stored is transferred to the additional calorifier depending
on the calorifier temperature top (TPO) and the additional
calorifier temperature bottom (TZU). The return loading is
carried out using pump additional calorifier-calorifier (PZP)
depending on TPO and the additional calorifier
temperature top (TZO) ( Ch. 7.20).
Possible settings MFA output:
0, 5, 6, 7, 8, 9, 10, 11, 12
