SECTION 6 – USER INTERFACE
There are three different methods that can be used to
interface with the Simplicity Elite control:
• Program buttons and display on the Unit Control-
ler
• Communication between the Unit Controller and
a PC or Personal Computer using “Simplicity
PC”.
• Communication between the Unit Controller and
a network
This section of the manual will explain how each of
these interface method is employed.
UNIT CONTROLLER INTERFACE
Four buttons located on the control board allow for
viewing and access to setpoints, alarms, functions,
etc. The buttons are used in conjunction with the two
numerical character displays located on the board.
The character display is a convenient way to access
information on the controller when a computer is not
available. Three of the buttons have multiple functions.
The button functions are discussed in detail below.
PROGRAM BUTTON
This button puts the board into the program mode. In
the program mode, the control displays the parameter
number of the two-digit display and the data for the
parameter of the four-digit display.
For example, the Occupied Cooling Setpoint is parameter
address 10. The addresses are listed on the Parameter
Points list. Pressing the program button once places
the board in program mode. The two-digit display
shows address 1 and the four-digit display shows the
current setting for that address. To scroll up to address
10, press the Test/Up button until address 10 appears
on the two-digit display. Address 10 is the Occupied
Cooling Setpoint. The factory default setting for this
parameter is 72º F. To change this setpoint, address the
Alarm/Change button one time. The temperature is now
fl ashing and may be increased or decreased by pressing
the Test/Up button or the Address/Down button. When
the desired temperature has been selected, pressing the
Alarm/Change button accepts and stores the change.
