5-58 Parameter Functions & Definitions
Table 5.BP
• When the standard control mode is selected, use the Control Period
(cool) parameter. The Control Period (heat) parameter cannot be used.
• When the heating control output is an analog output the control period
cannot be used.
• When the heating and cooling control mode is selected, the Control
Period can be configured independently for the heating and cooling
outputs. Use the Control Period (heat) parameter to set the Control
Output 1 side control period, and use the Control Period (cool)
parameter to set the cooling control period.

Direct/Reverse Operation
Function: This parameter allows you to configure the controller for the direct
or reverse operation of the manipulated variable (MV). Direct operation refers
to the control method where the manipulated variable is increased according
to the increase in the process value. Alternatively, reverse operation refers to
the control method where the manipulated variable is increased according to
the decrease in the process value.
Parameter Configurable Range Units Default Value
Control Period (heat) 0.5 or 1…99 Seconds 20
Control Period (cool) 0.5 or 1…99 Seconds 20
