I have an Ecobee 4

[newzealandescortspage]

Hi,

I have an Ecobee 4 unit that I would like to get connected to my Air Exchanger.

The Boiler works great.  The Air Exchanger is on it's own connection/circuit.  There are no interconnects.

The original wires going to the wall control were Y R G B.

I tried hooking up most connections to ACC-/ACC+ on the Ecobee and the unit is just not seeing anything to configure.

Wire B and G to the ACC terminals.
