POWERING the Unit ON/OFF

Before powering unit ON, check that power is available and proper connections have been completed.
Turn the disconnect switch to the ON position. The controller display keys and screen will illuminate and the proces-
sor will conduct a self-test (the screen will remain illuminated with no messages until the testing is complete). The
self-test takes approximately 20 seconds. Once completed, the Main Menu screen will be displayed. For initial pro-
gramming of setpoints, alarms, delays, etc., it is not necessary to have the unit ON. With the unit in the "OFF by Key"
mode, all settings are available to view and change (other than Menus J – Factory Settings and L – Configure Inputs/
Outputs) if the proper password is entered.
The Main Menu screen will display the unit type, date and time, and unit status. In addition, the screen will scroll and
display the temperature, relative humidity and operating mode.
The Unit Status will indicate the unit: "OFF by Key"
The unit may be turned ON at any time. Hold the ESC key for approximately 5 seconds. The display will continue to
scroll and display messages. At the same time the unit status is changed to "Unit On". Once powered there will be a
5-600 second start delay indicated by "Time Before Start: XXs".
Note: The start time delay is programmable from 5-600 seconds (Menu J – Factory Settings). The factory setting is 5
seconds.
