Final Engineer Notes :

We tested Honeywell T6 Pro for an Ecoer system, it did work.

Honeywell tsat G->G2 (indoor unit)
Honeywell tsat Y2->G (indoor unit)
Honeywell tsat Y1->Y (condensing unit)

PS: Y1 had output all the way. Y2 had a delay output from thermostat, even with big temperature difference between space and target one.
The compressor protection time may block the unit from turning on. So we turned it OFF because our condensing unit already equips compressor protection function.

Honeywell uses W2 for AUX/E in heat pump.
