Evaporator Refrig
Press Sensor
Offset= 00.0 psi
The pressure offsets on menus 7 and 8 and the temperature offset on menu 9 correct the
controller's display of the parameters. The sensors used in these units have a high degree of
repeatability but may need correction (offset). An accurate pressure gauge or thermometer
is used to determine the correct temperature or pressure. A positive or negative offset value
is then entered to make the controller reading agree with the measured value.

ENTER PASSWORD XXXX
Active Password
Level:None
Two four-digit passwords provide OPERATOR and MANAGER levels of access to
changeable parameters. The passwords are preprogrammed into the controller. The
Operator Password is 0100. Either password must be entered using the ENTER
PASSWORD (12) screen 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.
