6. By default, each thermostat’s board number in the
network list is indicated by a - (dash). To set the ad-
dress and begin communication, press
to
Commission. (If you have more than one MODBUS
network, specify which network you want the de-
vice to belong to.) A screen will open that will allow
you set the address:
7. In the list of MODBUS devices, choose the address
number corresponding to the thermostat’s dip
switch/jumper setting, and press
to select it.
If a network ID has already been selected, its name
will be shown next to the network ID in this list. If
the network ID you are trying to assign has already
been used, you must set the network ID dip switch/
jumper on this device to a different number that is
not being used.
8. Repeat
Steps 5
and
6
until each thermostat device
has been commissioned.
9. When finished, press
to return to the Net-
work Setup menu, then press
- Network Sum-
mary (
Figure 8-5
). Locate the thermostats you set
up, and look at each device’s status in the Status
field. You will see one of the following messages:
•
Online
- The thermostat is communicating normal-
ly.
•
Offline
- The thermostat is not communicating, has
not been commissioned, is not functional, or is not
powered up. Verify the thermostat is powered up,
wired correctly, and has the proper network address,
baud rate, and parity.
•
Unknown
- The thermostat is not communicating or
has not been commissioned. Verify the thermostat is
powered up, wired correctly, and has the proper net-
work address, baud rate, and parity.
•
No Port
- No port is set up in the E2 Serial Config-
uration Manager to be a MODBUS port.
•
Wrong FW Rev
- This message is likely caused by
the thermostat having a firmware version older than
the minimum revision required by E2 for communi-
cation. Replace the thermostat with a new controller
that has the latest version of firmware on it.
