Fig. 38 Alternative setpoints
Description
The function allows you to select up to six setpoints (2 to 7) as
alternatives to the primary setpoint (1). The primary setpoint (1) is
set in the menu "Operation".
Every alternative setpoint can be addressed manually to a
separate digital input (DI). When the contact of the input is
closed, the alternative setpoint applies.
If more than one alternative setpoint has been selected, and they
are activated at the same time, CU 352 selects the setpoint with
the lowest number.
