Ă• In heating and cooling control, the manipulated variable output that is
output when controller operation is stopped is dependent on the set valĆ
ue of the MV at reset" parameter (level 2 mode) in the same way as for
standard control.
Ă• However, note that in heating and cooling control, the manipulated variĆ
able at the cooling side is treated as a negative value for the sake of conveĆ
nience. When the manipulated variable at reset is a negative value, the
manipulated variable is output to only the cooling side, and when a posiĆ
tive value, the manipulated variable is output to only the heating side.
Default is 0". If the controller is operated with default, the manipulated
variable is not output to both the heating and cooling sides.
When the overlap band is set, the bumpless function that operates when switching
between manual and automatic operation may not work.
