The sequence contact gap can be specified in °C in relation to the setpoint of
contact I.
(The contact track no. is stamped on the back of the housing par.)
Prefix - = switching before reaching the setpoint value
Prefix + = switching after reaching the setupoint value
For the synchrozized version, specify "0" as the sequence contact gap.
