I installed both ecobee thermostats and wired them in with a two-stage option. I change the outdoor capacity setting to its lowest setting of 4 tons. I change the indoor blower speed to low low. I put the Y2 call on blower speed low medium both units are now producing a better temperature split. However, the unit with the supply dock tapped off the end does not perform as well as the other unit unit. Units are operating properly for conditions at this time
