hello, I have a Lifebreath 155 Max. We have the switches in our bathrooms and kitchen but I wanted to a a digital controller. I purchased a 99-DXPL02. Currently I have a controller on the unit as shown here (https://ibb.co/ZzqJ2VX)

How do I add the other one too or do I have to remove this one and replace it with something else ?
Only one master control should be installed. Just wire the 99-DXPL02 to the Red, Yellow, Green terminals on the HRV.
I don't have a block like that, mine is the one that is in the link.
I can't see most of the terminals. I see RED. Is there a GRN and YEL? Do you still have the manual by chance? I've never seen one with an integrated controller. Do your existing switches have LED lights?
I would try wiring the 99-DXPL02 to the RED, GRN and YEL terminals and it should work.
