Table 24 — Configuring Schedules (Example)
When OCC1PxxS is set to a value of 65 or greater and a time
schedule is configured for at least one occupancy period, the
system will assume that the unit is going to be the master ele-
ment for this schedule (the system element doing the broad-
casting). In that case the unit Equipment and Supervisory part
table names will be automatically modified to OCCPCxxE and
OCCPCxxS.
By configuring their appropriate Time Schedule decisions to
the same number, other devices on the network can follow this
same schedule. The Enable-Off-Remote Contact must be in the
Enable position or the Remote Contact position with the con-
tacts closed for the unit to operate.
The Unit Run Status (Main Menu
General Parameters
Run Status) will indicate the current status of the machine de-
pending on the schedule. The unit Occupied status (Main
Menu
General Parameters
Setpoint Occupied) will in-
dicate the current occupied schedule according to the schedule,
either NO or YES.
The Status Unit Control Type (Main Menu
General Pa-
rameters) will be 0 when the switch is Off. The Status Unit
Control Type will be 2 when the Enable-Off-Remote Contact
switch input is On.
CCN Control
To operate under this control, Network must be selected under
the Select Machine Mode accessed by touching the Start/Stop
button (see “MACHINE CONTROL METHOD SELECTION”
on page 26).
An external CCN device such as Chillervisor controls the On/
Off state of the machine. Careful evaluation of Chilled Water
Plant control is necessary. In the event Local Control is estab-
lished, be sure that all pumps, valves, and other devices are ca-
pable of operating properly. In the event of a loss of communi-
cation with the network, the machine will start and be con-
trolled locally. The CCN device forces the variable CHIL_S_S
to control the chiller. The Unit Run Status (Main Menu
General Parameters
Run Status) will indicate the current
status of the machine (OFF, RUNNING, STOPPING or DE-
LAY), depending on the CCN command. The unit Occupied
status (Main Menu
General Parameters) will indicate the
current occupied state according to the CCN command and
will be displayed as either NO or YES. The Status Unit Control
Type (ctrl_typ) will be LOCAL OFF when the Start/Stop but-
ton is Off. The Status Unit Control Type will be CCN when the
Enable-Off-Remote Contact switch input is Closed and the
CHIL_S_S variable is Stop or Start. For dual chiller control
applications, the slave chiller must be enabled using the CCN
CONTROL option.
CHILLED WATER FLUID TYPE SELECTION
The chilled water fluid type must be configured to obtain the
proper leaving water set point control range and freeze protec-
tion. The Evaporator Fluid Type (flui_typ) (Main Menu

Fluid Type) can be set to water or brine.
To configure this option:
Fresh Water
Configure the unit Evaporator Fluid Type to Water for units with-
out brine or glycol installed in the chilled water loop. The factory
default fluid type is fresh water. This option will allow for a water
