Parameter Functions & Definitions

5-37

In the heating and cooling control mode, the cooling Control Output side P is
calculated by the following formula to configure the cooling coefficient:

Cooling Control Output side P = Cooling coefficient x P (proportional band)

Dead Band

Conditions of Use:

The control system must be configured for the heating

and cooling control mode.

Function:

This parameter allows you to configure the output dead band width

in a heating and cooling control system. A negative value configures an overlap
band.

This parameter sets an area in which the Control Output is 0 centering around
the set point in a heating and cooling control system (refer to Figure 4.25).

The decimal point setting follows that of the currently configured sensor.
When using an analog input, the decimal point setting follows the Decimal
Point position configuration.
