Went through the system and found the slave thermostat was keeping the dampers open even when there wasn’t a call for cooling. This was causing the system to over cool the master bedroom and guest bedroom. Contacted EWC and went through the the troubleshooting procedures. Flipped the ds 1 and 2 switches in the ac to get communication where it should be and set the zone weights. Zone system is operating properly at this time. Air flow: customer is heating a lot of noise in the return duct in the hallway and bedroom near the furnace. Tested airflow and wasn’t getting anything upstairs and a little bit in the master bedroom but it seemed like everthing was going through the return in the hallway. Talked to chad and he needs to come down to see if he can damper it and he also wanted a picture of the register. Thanks Brad
