Two four-digit passwords provide OPERATOR and MANAGER levels of access to
setpoints. The passwords are preprogrammed into the controller. The Operator
Password is 0100, the Manager Password is 2001. Either password must be entered
using the ENTER PASSWORD screen (15) before a protected setting can be changed.
This screen can be accessed either through the SET OTHER menu, or by simply
pressing the ENTER key while on one of the SET screens. The controller will
automatically go from the screen with the setting change to this screen. After the
correct password has been entered, the controller will automatically return to the
original set screen.
Once a password has been entered, it remains valid for 15 minutes after the last key-
press.
SET UNIT SPs (1)
Unit Enable=OFF
Mode=COOL
Source=KEYPAD
Unit Enable is an external signal, or a keypad setting, that keeps the unit off when the
setting is OFF, and allows it to run if there is a call for cooling when the setting is ON.
The source for the signal is selected in the 4
th
line and can be:
1. KEYPAD, in which case the selection is made in line 2 and would be normally
selected as ON. This is the normal setting when no external signals are controlling
the unit.
2. DIGITAL INPUT, in which an external switch is wired across terminals #52 and
#72. (See wiring diagram page 50).
3. BAS, used with BAS signal.
