other and to 24 VAC0.

Relays 1…6, normally-open
contacts
35…39 IN1…5 --
Common contacts of relays
1…5. May be set to common
supply voltage via terminal 40
by inserting jumpers J1…J5 into
their lower positions. When, in
contrast, a jumper is in the
upper position (the so-called
“parking position” = default
setting), the corresponding relay
receives no supply voltage from
terminal 40.
40 IN6 --
Common contact of relay 6,
internally connected to the
middle contact of jumpers
J1…J5. May be used to connect
common supply voltage.
