⚠ CAUTION ⚠

ZONE VALVE NOTES:
The EWC zone panel opens all dampers
when no zones are calling, which is ne
for dampers, but is not optimal for zone
valves. When using zone valves on the
output (left side), zone 4 should be used
as a “control zone” to make sure that the
zone valves will be closed when there is
no thermostat call. For addtional zones,
use a 2-zone expansion panel, Enertech
part # AZZXM-2.

⚠ CAUTION ⚠
ALL FAN COILS MUST BE 2 TONS OR LARGER FOR
THIS APPLICATION. IF ANY FAN COIL IS SMALLER
