0 to 50°C (32 to 122°F)
-40 to 70°C (-40 to 158°F)
6.3-mm (1/4-in.) spade lugs (Communication has screw terminals.)
N2 Bus and Zone Bus
DIP switch set (1-253) Addresses 254 and 255 are reserved. Software addressable
with the HVAC PRO program Release 7.02 or later, or the VBT program
N2 between VMA and NCM/N30 (3-wire). Zone Bus between VMA and room sensor
(8-pin phone jack or wire to spade lugs or optional plug-on terminals)
One screw (included) mounts the VMA1410/1420 to the VAV box. One screw
attaches damper shaft to the actuator, 8-mm (5/16-in.) square head set screw with
44 N . m (375 lb . in) of axial holding power for up to 13-mm (1/2-in.) round damper
shafts. Minimum damper shaft length is 44.5 mm (1-3/4 in.). Use two screws
(included) to mount the VMA1430 to the VAV box.
