5 - PRO-DIALOG CONTROL OPERATION
5.1 - Start/stop control
The table below summarises the unit control type and stop or
go status with regard to the following parameters.
- Operating type: this is selected using the start/stop button
on the front of the user interface.
- Remote start/stop contacts: these contacts are used when
the unit is in remote operating type (rEM). See sections
3.6.2 and 3.6.3.
- CHIL_S_S: this network command relates to the chiller
start/stop when the unit is in CCN control (CCn). Vari-
able forced to disable: the unit is halted. Variable forced to
Enable: the unit runs in accordance with schedule 1.
- Start/Stop schedule: occupied or unoccupied status of the
unit as determined by the chiller start/stop program
(Schedule #1). Used when the unit is equipped with an
optional CCN/clock board, otherwise the chiller occupied
mode is forced to occupied all the time.
- Master control type. This parameter is used when the
unit is the master unit in a two chiller lead/lag arrange-
ment. The master control type determines whether the unit
is to be controlled locally, remotely or through CCN (this
parameter is a Service configuration).
- CCN emergency shutdown: if this CCN command is
activated, it shuts the unit down whatever the active
operating type.
- General alarm: the unit is totally stopped due to failure.
