Modulating Reversible Heat Pumps

[Jasmine]

Hello,

I am trying to simulate a system using a reversible, ground source heat pump. In order to achieve the desired regulation, I would need to modulate the output of the heat pump with the desired power output. However, when I enter the reversible heat pump, the modulation column in the heat pump catalog disappears. Is there a way to achieve this?

Thank you for your help,

Jasmine
