140 Function of temperature sensor S5

Circuit
II
For heating system types 2, 2a, 3 and 6a, sensor S5 can be
used optionally as lower DHW tank temperature sensor (cut-
out temperature) or as return temperature sensor in circuit II
(limitation of the return temperature).
ON: Return temperature sensor in circuit II. The
The return temperature limitation of the heating circuit (circuit I)
is carried out by sensor S3 (lines 31-37).
OFF: Lower DHW tank temperature sensor. DHW
The return temperature limitation of the heating circuit (circuit I)
and DHW circuit (circuit II) is carried out by sensor S3 (lines 30-37).
The return temperature limitation is the highest return
temperature limitation of the two limitations in the heating circuit
and the DHW circuit.
The return temperature limitation is defined in lines 31-37
(heating circuit) and in lines 30, 35, 36 and 37 (DHW circuit).
