Outputs:
A1 Storage cylinder 1 fill pump (speed
control)
A2 Storage cylinder 2 fill pump (speed
control)
A3 Additional relay, freely programmable
function
Inputs:
F1
Collector 1 temperature probe
F4
Temperature probe at bottom of stor-
age cylinder 1 / A1 max. temp. moni-
toring (when F3 not fitted)
F2
Temperature probe at bottom of stor-
age cylinder 2 / A1 max. temp. moni-
toring (when F5 not fitted)
F3
(optional) Temperature probe at top
of storage cylinder 1 / A1 max. temp.
monitoring and reference probe dur-
ing heating
F5
(optional) Temperature probe at top
of storage cylinder 2 / A1 max. temp.
monitoring and reference probe dur-
ing heating or for return temperature
control
Impulse (optional) pulse transducer for volu-
metric meter or circulating pump con-
trolled by impulses
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 (or F4) > P50
ON: F3 (or F4) < P50 - 5°C
Maximum collector temperature
OFF: F1 > P42
ON: F1 < P42 - 10°C
Switching conditions for A2:
Heat production (difference between storage
cylinder and min. temp.)
ON: F1 - F2 > P32 and F1 > P40
and A1 = OFF
OFF: F1 - F2 < P33 or F1 < P41
or A1 = ON
Maximum storage cylinder temperature:
OFF: F5 (or F2) > P51
ON: F5 (or F2) < P51 - 5°C
Maximum collector temperature as for A1!
