Variation 32: Calorifier with internal tank for DHW and collector cascade
The WRSol 2.0 determines the temperature differential
between the collector sensors (TKO or TK2) and the
reference sensor (TPU or TSU).
As soon as the temperature differential is greater than the
increase (... Diff. On ) set, the relevant solar pump
(PS or PS2) is activated.
Once the increase ( ... Diff. Off ) or the maximum
calorifier temperature has been reached the solar pump is
switched off. TSU or TPU is selected as reference sensor.
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 33: Calorifier with internal tank for DHW and collector cascade/bypass
The WRSol 2.0 determines the temperature differential
between the collector sensors (TKO or TK2) and the
reference sensor (TPU or TSU).
As soon as the temperature differential is greater than the
increase (... Diff. On ) set, the relevant solar pump
(PS or PS2) is activated.
Once the increase ( ... Diff. Off ) or the maximum
calorifier temperature has been reached the solar pump is
switched off. TSU or TPU is selected as reference sensor.
The three way valve (VBY) is switched over depending on
the collector temperature (TKO or TK2) 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, 5, 6, 7, 8, 9, 10, 11, 12
