Navigator Display Machine Control - Carrier AQUAFORCE 30XA080-500 Controls, Start-Up, Operation, Service And Troubleshooting Instructions

displayed. Select Remote Mode. The unit will be controlled by
the Enable/Off/Remote Contact switch. Switching the Enable/
Off/Remote Contact switch to the Enable or Remote Con-
tact position (external contacts closed) will force the unit into
an occupied state. In this mode, all CCN network force com-
mands, except the Emergency Stop Command will be ignored.
The Run Status variable will indicate the current status of the
machine (OFF, RUNNING, DELAY, or READY), depending
on the position of the Remote/Off/Enable Switch closure. The
Chiller Occupied? variable will change to YES. The Control
Type variable will change to Remote. The Operating Type
variable will change to Remote.
Master Mode — To activate Dual Chiller Control, each ma-
chine must be individually configured for Dual Chiller Control.
To operate the machines in Dual Chiller Mode, one machine
must be designated as the master unit and one machine as the
slave unit. On the master unit, press the Start/Stop button on the
Touch Pilot display. The Equipment Start screen will be dis-
played. Select Master Mode. Failure to start the Master unit in
this manner will cause both machines to operate in local mode.
The Master Unit Control can be done locally, remotely or
through CCN commands per the master/slave configuration
(Master Control Type). The control will ignore the position of
Enable/Off/Remote Contact switch if the Master Control
Type is configured for Local Control or CCN Control. The
Run Status variable, Chiller Occupied? variable, and Con-
trol Type variable will change based on the Master Control
Type configured above and the Machine On/Off Control de-
fined above. The Operating Type variable will change to
Master.
To Turn Machine Off — To turn the machine off, press the
Start/Stop button on the Touch Pilot display. See Fig. 19. The
machine will shut down. While the unit is in Local Off, it will
remain shut down and ignore all CCN commands as well as
the position of Enable/Off/Remote Contact switch. The Run
Status variable, indicating the current status of the machine,
will change to OFF. The Chiller Occupied? variable will
change to NO. The Control Type variable will indicate
Local. The Operating Type variable will change to L-OFF
(Local Off).
NAVIGATOR™ DISPLAY MACHINE CONTROL —
Machine On/Off control with the Navigator display is deter-
mined by the configuration of the Operating Type Control
(OPER). Options to control the machine locally via a switch,
from a local Time Schedule, or via a Carrier Comfort Net-
work command are offered. See Table 21.
