Positive means that operation of the relay is not inverted:
The relay is energized when the controller activates the function output (e.g. Cooling = ON).
(This means that the contact of a normally open relay is closed.)
The relay is not energized when the controller deactivates the function output (e.g. Cooling = OFF).
(This means that the contact of a normally open relay is open.)
Inverted means that operation of the relay is inverted:
The relay is not energized when the controller activates the function output (e.g. Alarm = ON).
(This means that the contact of a normally open relay is open.)
The relay is energized when the controller deactivates the function output (e.g. Alarm = OFF).
(This means that the contact of a normally open relay is closed.)
