The STATUS point can have the following values:
Off > STATUS = 0
Ready > STATUS = 5
Running > STATUS = 1
Override > STATUS = 6
Stopping > STATUS = 2
Defrost > STATUS = 7
Delay > STATUS = 3
Run Test > STATUS = 8
Tripout > STATUS = 4
Test > STATUS = 9
3
Permits starting/stopping the machine, in CCN mode only. The override value is displayed, but only used, if the unit is in CCN mode.
4
Indicates if the unit is in occupied mode or not. In CCN mode the value can be forced and used instead of actual occupancy status,.
7
Demand limit active. This point can be forced in CCN mode and this override value will have priority over the other limit values (external or limit control).
8
Control point. This point can be forced in CCN mode and this override value will have priority over the value calculated by the control.
9
Always active if the unit is not in CCN mode.
10
Setpoint selection. This point can be forced in CCN mode and this override value will have priority over the setpoint selection in Remote mode.
