Answers

Answer: 
The Honeywell MARD is a round damper with a 24-Vac, floating-control type modulating motor for bypass and zone damper control. The dampers themselves do not have the ability to sense if the system is in heat or cool. It would rely on the system and zone panel it is wired to, to determine whether or not it needs to be open or closed on a call for heating or cooling.

In the application you describe, you would need to install a temperature controller capable of powering the damper open and then closed, depending on whether it was set for heating or cooling and what the temperature needs were.
