Name

Type 1

Description

Default Value

Deadband

 

Indicates an area of a signal range or band where no action occurs and the State outputs a Hold.

2

Down Delay

 

Indicates the minimum time after a Stage Down that another operation (Stage Up or Stage Down) can be performed.

10

Display Units: Minutes

HeatingCooling

 

Inverts the action of the Stage Up/Stage Down.

Heating

Set Name: Heating/Cooling
