Hi!
I'm planning to do some automation of my air exchanger. I'd like to control when to exchange/recirculate air and when to switch speeds. I googled around but couldn't find any information concerning the communication protocol between the exchanger and the control unit.
My air exchanger is a Venmar, but from what I can see, vanEE is the same thing.
I think it must be pretty simple. I think it's not hardwired, because of the quantity of modes to choose from (off/min/max + damper opened/closed) which would require 3 wires, + 2 for suply/ground for the leds. There are only 4 wires between the unit and the control. I guess they are using something like RS-485.
Did anyone of you see any info regarding this on the web?
Thanks
Patrick
