23 = Solar integration (to MF4 because of PT1000
sensor)
T-SOL PANEL [T-MF4] = Temperature of the solar
collector
T-DHW L [F12]= Temperature of hot water storage tank in
infeed area
ON: T-SOL PANEL >
[T-DHW L + MF4 HYST + 5K]
OFF: T-SOL PANEL <
[T-DHW L + MF4 HYST]
The pump is switched on when the temperature of the
solar collector exceeds the temperature of the storage tank
in the infeed area (T-DHW L) by the Hysteresis (MF4
HYST + 5K). Switching off occurs when the temperature
drops 5K below the switch-on temperature.
Safety / system protection:
OFF: T-DHW B > T-MF4 SETP
ON: T-DHW B < [T-MF4 SETP – 5K]
Switching off occurs when storage tank temperature
exceeds the set limit temperature (T-MF4 SETP). The
pump is enabled again when the storage tank temperature
drops below the limit temperature by 5K.
24 = Return flow temperature increase HS1
T-RETURN 1 = Return flow temperature from the
installation [= T-MF1 or 1-4].
ON: T-RETURN 1 < T-MF1 SETP
OFF: T-RETURN 1 > [T-MF1 SETP +MF 1 HYST]
The return flow temperature increase pump is switched on
if the return flow temperature drops below the temperature
setting limit (T-MF1 SETP). It is switched off again when
the return flow temperature exceeds the temperature
setting limit by the Hysteresis (MF 1 HYST).
25 = Return flow temperature increase HS2
T-RETURN 2 = Return temperature of system
ON: T-RETURN 2 < T-MF1 SETP
OFF: T-RETURN 2 > [T-MF1 SETP +MF 1 HYST]
The return flow temperature increase pump is switched on
if the return flow temperature drops below the temperature
setting limit (T-MF1 SETP). It is switched off again when
the return flow temperature exceeds the temperature
setting limit by the Hysteresis (MF 1 HYST).
26 = Return flow temperature increase HS via buffer
storage
ON: T-BUFFER B [F1] > T-MF1 +MF 1 HYST + 5K
OFF: T-BUFFER B < T-MF1+MF 1 HYST
The valve to the return flow temperature increase via the
buffer storage is opened if the temperature buffer storage
low [T-BUFFER B] exceeds the return flow temperature of
the installation [sensor 1 or 1-4] by the Hysteresis (MF 1
HYST + 5K). It is switched off again when the temperature
buffer storage low drops below the return flow
temperature.
