F1 = temperature probe F1
F2 = temperature probe F2
F3 = temperature probe F3
F4 = temperature probe F4
F5 = temperature probe F5
P30 = parameter 30
Switching conditions:
e.g.
ON: F1 - F4 > P30 and F1 > P40
(temperature F1 minus temperature F4
greater than parameter 30 and tem-
perature F1 greater than parameter
P40)
OFF: F1 - F4 < P31 or F1 < P41 (tempera-
ture F1 minus temperature F4 less
than parameter P31 or temperature F1
less than parameter P41)

Sensor:
The sensor in the collector must
be type KLF 1000 (cable with silicone
sheath). For all other applications, type
SPF 1000 can also be used.
b
For the electrical connections (230V),
flexible wires must be used with prop-
erly attached ferrule cable ends.
b
The BUS wires and sensor lines must be
laid separately from the network wires!
