Readdress New Fan
Replacement fans must be readdressed prior to unit operation. Refer to section Fan and Motor Removal & Installation on
Page 31 for instructions on removing and installing fans. Each fan needs to be assigned a unique address, starting with
"1,2,3,...". Replacement fans are pre-programmed with a default Modbus address of 247. Only one new fan should be
readdressed at a time. To address a newly installed fan:
1.
Log in as Technician. Refer to Table 8. Access Levels and Passwords on Page 43.
2.
Navigate to Settings menu, Technician Page 2 of 2 as shown in Figure 78.
3.
Use the dropdown menu titled "Select Fan to Replace" to select the correct fan number. Refer to Figure 79 to identify
the correct fan number.
4.
After selecting the fan that has been replaced, press the "Search" button. "Searching for Fans..." will be displayed to
the left of the Search button.
5.
When the new fan has been detected, a green checkmark icon will appear as shown in Figure 80. Press the
"Readdress" button. Next press the "Readdress Fan" button to confirm readdress. The selected fan will be
readdressed.
