The Keypad enable signal cannot be modified with the user password level. If it is set to Disable
contact your local maintenance to check if it can be changed to Enable.
The last enable signal is coming through the high level interface, that mean from a Building
Management System. From a BMS connected to the UC using a communication protocol the unit
can be disabled. To see if the enable signal is coming from a BMS in the View/Set Unit and then
Status/Settings check the Control Source, if it is set to Network than the Network En SP setpoint in
the same page will reflect the actual signal coming from the BMS. If the value is set to Disable then
the unit cannot start. In this case check with your BAS company how the chiller is operated.
