display Figure 4.
To turn the unit on, press the ON/OFF key after power is applied. To turn the unit off, press the ON/

Active alarms are indicated on the LCD screen by a ringing bell graphic. Alarms are also annunciated

Setpoints, DIP switch settings, and other selections were made on your unit after testing at the fac-
tory and are kept in nonvolatile memory. Setpoints were chosen based on typical operating experi-
ence. Other selections were made based on options included with your unit. Make adjustments to the
factory default selections ONLY if they do not meet your specifications. When entering setpoints, time
delays, etc., the allowable ranges are displayed and may require a password, if enabled.
