Upon arrival customer informed me that he wasn’t sure how zoning system was setup and thinks he may have problem with 2nd zone on main system. Checked thermostat settings and changed 2nd zone demand to 70% and 3rd zone to 40%. Basement is unfinished and 2nd zone wasn’t getting signaled quick enough because of % demand setup. Verified all damper actuators are opening and closing on demand. Also found AWL Ethernet plug was inserted into wrong port on AWL. Switched from aid tool to abc port and system connected to AWL. Then found humidifier was getting signal but water not running. Water valve not opened. Opened and tested humidifier operation. When fan is running the humidifier was whistling. Found an air gap, sealed with tape. Found filter was dirty, customer provided replacement. System had faulted on condensate so I cleaned out drain line and tested condensate pump. Packaged unit operating normal. Went to Horizontal unit and found system had tripped on FP1. Found dipswitch was set
