Ruud econet system with EWC ECONET 3 zone panel acting strange

[Btettemer]

I installed the following equipment last July

1-Ruud condenser model UA1736AJ2CB
1- Ruud furnace model U96VA0852521MSB
1- Ruud coil model RCF3621MTAMCA
1- Ruud Econet Thermostat UETST700SYS
2- Ruud Econet zone controllers model RECTL700ZON
1- EWC ECONET zone control panel
3- various size EWC ND motorized dampers

The customer brought to my attention the system wasn't cooling. When I arrived I found that even though all 3 t stats were calling for cooling only the 1st zone (main controller) was lit up in the panel. In addition, the condenser would not come on. There is no error codes on the furnace, condenser, or the thermostat. So I shut it down and powered it back up. All 3 zones lit up and then shut off except for zone 1 again.

The system has worked fine for almost a year. Your thoughts on a zone panel issue?
