Make sure that communication wires from E1 and E2 terminals at the Command Center mounting bracket are securely
connected at the E1 and E2 terminals respectively on the first controller board in the daisy chain. Make sure all controllers on
the daisy chain network are powered on and properly addressed so the Command Center can find them. For Group Leaders and
Followers, the address is set at each controller under
Settings →Equipment→Group‐Member Cfg.
For standalone units on the
daisy chain, the address is set at each controller under
Settings→Equipment→Network Instance
. Make sure that at least 22
gauge, shielded wire is used. Please refer to the EcoNet Installation Manual for how to daisy chain multiple controllers
together with a Command Center Display.
Make sure that every evaporator controller in the daisy chain network is powered on.
Make sure all controllers on the daisy chain network are powered on and properly addressed so the Command Center can find
them. Every EcoNet board on the daisy chain must have a unique address set. For Group Leaders and Followers, the address is
set at each controller under
Settings →Equipment→Group‐Member Cfg.
For standalone units on the daisy chain, the address is
set at each controller under
Settings→Equipment→Network Instance
.
Make sure that communication wires from E1 and E2 terminals at the Command Center mounting bracket are securely
connected at the E1 and E2 terminals respectively on the first controller board in the daisy chain. Make sure that the
communication wire is securely connected to the E1, E2 and RT terminals between every controller board, and that the wires
are not crossed from terminal to terminal. Make sure that at least
22 gauge, shielded wire
is used. Make sure that the
shielding strands are tied together at every splice and tied to a ground point at one end of the daisy chain only. Make sure all
controllers on the daisy chain network are powered on and properly addressed so the Command Center can find them. Please
refer to wiring diagram the EcoNet Installation Manual for how to daisy chain multiple controllers together with a Command
Center Display.
Make sure that communication wires between
Command Center Display and EcoNet controller
are properly connected.
Command Center Display turns on and is
able to communicate with some
controllers, but not with others on the
daisy chain network.
Command Center Display turns on but is
not communicating with any controllers.
Make sure that communication wires between
Command Center Display and EcoNet controller
are properly connected.
Possible conflict of addresses on the network.
Some Evaporator Controllers in the network bus
may not be powered on.
