Operating mode with Direct/Reverse change-over
from digital input [PRO=6]
• When in this mode both outputs operate in direct (with set-point 1 and differential
1) or both in reverse (with set-point 2 and differential 2) depending on digital input
status.. More precisely, in direct if the digital output is open and in reverse if it is
closed. Operating functions are the same as in modes 0 and 1. Therefore both set-
points [ST1] and [ST2] and both differentials [DF1] and [DF2] must be confi gured.

Direct operating mode with set-point and differential change-over
from digital input [PRO=7]
• When in this mode both outputs operate in direct, with set-point 1 /differential 1
or set-point 2/differential 2) depending on digital input status. More precisely, with
set-point 1/differential 1 if the digital input is open and set-point 2/differential 2 if it
is closed. Operating functions are the same as in mode 0. Both set-points [ST1] and
[ST2] and both differentials [DF1] and [DF2] must be confi gured.
