Two new chiller states have been added to MCS-Connect:

 #29 “Maximum Run Time”
7.80.2.1. Magnum HVAC software only
Function 1: (Factory authorized startup is required)
When the password for Factory Startup is entered using the MCS-Magnum Keypad/LCD the user is allowed
to activate the function to lockout the Magnum until Factory Startup authorization is given. When activated the
chiller state will be FACTORY STARTUP, the Magnum will not allow the unit to run, and the only screen that
will be enabled is Passwords. If the Magnum is reset the chiller state will be FACTORY STARTUP not UNIT
IN POWER UP. Once the system state is FACTORY STARTUP the system can be accessed from MCS-
Connect but the system will not accept changes to Relay Output states.
When the password for Factory Startup activation is entered and the function is active, the user is allowed to
deactivate it. When deactivated the chiller state will be changed to UNIT IN POWER UP and normal
operations will be allowed.
To activate the Factory Startup function from the Magnum keypad, open the Password menu option and enter
the Factory Startup password. The following pop-up will appear asking if you would like to activate this feature.
When active, the following heading will appear on all Status screens, showing that the unit is locked out until
Factory Startup authorization is entered.
