Weishaupt WRSol 1.0 Manual page 33

Variation 43: Calorifier with internal tank for DHW with collector and solid fuel boiler
• Energy yield calculation (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TPU).
As soon as the temperature differential on the reference
sensor is greater than the value set ( ... Diff. On ), the
solar pump is switched on and the storage tank is topped
up until the switch off condition ( ... Diff. Off ) or the
maximum calorifier temperature has been reached. TSU or
TPU is selected as reference sensor.
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 44: Calorifier with internal tank for DHW with collector/bypass and solid fuel boiler
• Energy yield calculation (optional;
The WRSol 2.0 determines the temperature differential
between the collector sensor (TKO) and the reference
sensor (TPU).
As soon as the temperature differential on the reference
sensor is greater than the value set ( ... Diff. On ), the
solar pump is switched on. TSU or TPU is selected as
reference sensor.
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
( ... Diff. 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
