Lifebreath 155max

[nick22]

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

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.
