7.2 Setting Up a Work Group
A workgroup can consist of up to eight controllers (I/O boards) with pLAN addresses 1 to 8. Their corresponding display terminals
will be assigned pLAN addresses from 32 down to 25. The E² controller program is defaulted with the controller address set to 1
and its terminal (display) address set to 32. As such, a normal stand-alone controller does not need any changes made to either the
controller or the terminal address. The method to setting up work groups is to retain the fi rst (group lead) controller's pLAN address
as #1 and terminal address as #32 so that the sum of the addresses equals 33. The fi rst controller added to the group is assigned
pLAN address #2 and its terminal is assigned address #31, the sum of which again equals 33.
NOTE:
The sum of the controller and terminal address numbers must always equal 33.
The A/C units in a work group should ALWAYS start with controller address 1 and go up from there. DO NOT skip over controller
addresses. The list of suitable controller/display terminal address pairs is shown below:
Corresponding A/C Unit Controller to Terminal pLAN Addresses
Controller (I/O board) 1 2 3 4 5 6 7 8
Display Terminal 32 31 30 29 28 27 26 25
Assign the terminal and controller I/O board addresses for each controller to be grouped. Review Sections 7.2.1 to 7.2.3 fi rst,
before turning power on and the assigning addresses. Do not interconnect the controllers together before assigning their terminal
and I/O board pLAN addresses.
The fi rst step is to change the terminal address of each controller to 0 referring to Section 7.2.1. Set the terminal address to 0
before assigning the controller (I/O board) address.
NOTE:
If the terminal remains inactive (no key is pressed) for more than 30 seconds, the group set-up procedure is exited
automatically, without saving any changes.Confi gure the Terminal Address
7.2.1 Confi gure the Terminal Address
The address of the terminal (display) can only be confi gured if its RJ11 telephone jack is connected to the I/O control module in
the electric box and power is turned on. The factory default value for the display terminal address is 32. To reassign the terminal
address, press and hold the Up ( ), Down ( ) and Enter ( ) keys simultaneously for fi ve seconds until the Address Confi guration
screen shown below appears with the fl ashing cursor in the top left corner:
1. To change the address of the terminal (Display address setting), press the Enter ( ) key
once. The cursor will move to the address fi eld (nn).
2. Using the Up ( ), Down ( ) keys, select 0 and confi rm by pressing Enter ( ).
The Display Address Changed screen will appear indicating the display address selected
is not the same as the one saved previously and the new value will be saved to the per-
manent memory.
3. Once the terminal address is set to zero, cycle the power to the unit Off and then back On.
NOTE:
If the Display address setting fi eld is set to 0, the terminal will communicate with the
controller using point-to-point protocol (not pLAN). The display fi eld I/O Board address
will disappear as it has no meaning until the controller I/O board pLAN address is set.
7.2.2 Confi gure the I/O Board pLAN Address
Immediately after turning power back on, press and hold the Alarm ( ) and the Up ( ) Arrow keys
simultaneously for 10 to 15 seconds. First a display message “self test please wait” will appear then the pLAN Address Confi guration
screen shown below will appear. Don’t press the ( ) key, the cursor is already in the modifi able fi eld.
Press the ( ) key to set the pLAN address (#1 – 8) for the controller (I/O Board). The pLAN
address #1 is already assigned by default to the fi rst (Lead) controller in the group. Address
#2 is to be assigned to the fi rst controller added to the group (address #3 is to be assigned
to the second controller added and so on). Then press the ( ) key to confi rm the selection.
A message NO LINK will appear.
