4.1 Selecting the Control Method
E5EK

•
In heating and cooling control, the manipulated variable output that
is output when controller operation is stopped is dependent on the set
value of the “MV at reset” parameter (level 2 mode) in the same way
as for standard control.
•
However, note that in heating and cooling control, the manipulated
variable at the cooling side is treated as a negative value for the sake
of convenience. When the manipulated variable at reset is a negative
value, the manipulated variable is output to only the cooling side, and
when a positive value, the manipulated variable is output to only the
heating side.
Default is “0”. If the controller is operated with default, the manipu-
lated variable is not output to both the heating and cooling sides.
When the overlap band is set, the bumpless function that operates when switch-
ing between manual and automatic operation may not work.
