1.Setp+Pband1/2
(15D)
for control circuit 1: Switch over Setpoint 1/2 and Pband 1/1
When programming this function,
“ Setting ” additionally lists
the parameter: “ 1.Pband 1. for control circuit 1 ”
First control circuit Set-
point 2 + Pband 2
Only active in operation with a second control circuit
E1 / E2
(4D)
The output for control circuit 2 is additionally set to “ A2 ” to
“ A1 ” (regardless of the programmed function for “ A1 ” ). The
fi rst control circuit has no output for the duration of the switch
over.
The switch over input
“ E1 ” / “ E2 ” as in operation with one
control circuit is no longer possible.
