Inputs:
F1
Collector temperature probe
F4
Temperature probe at bottom of stor-
age cylinder
F3
Temperature probe at top of storage
cylinder (max storage cylinder tem-
perature monitoring)
F2
(optional) Storage cylinder tempera-
ture, heat flow measurement
F5
Reference probe (optional) for return
temperature control
Impulse (optional) pulse transducer for volu-
metric flow meter
Switching conditions for A1
Heat production (difference between storage
cylinder and min. temp.)
ON: F1 - F4 > P30 and F1 > P40
OFF: F1 - F4 < P31
or F1 < P41
Maximum storage cylinder temperature
OFF: F3 > P50
or F4 > P50
ON: F3 < P50 - 5°C and F4 < P50 - 5°C
Maximum collector temperature
OFF: F1 > P42
ON: F1 < P42 - 10°C
Switching conditions for A2:
ON: A1 = ON and F2 - F3 > P32
and F3 < (P50 - P32)
OFF: A1 = OFF
or F2 - F3 < P33
or F3 > (P50 - P33)
