APPENDIX F — GLOBAL TIME SCHEDULE CONFIGURATION FOR i-Vu®DEVICE

AND CSM CONTROLLER (cont)

Step 2 — Chiller Mode Selection — There are 3 different mode selections for the chiller which are described below. In order to change the mode from the default configura- tion, a scrolling marquee or handheld Navigator™ device must be used.

1.Using a Navigator device, select Operating Modes → SLCT → OPER, then enter the password.

2.The screen defaults to SWITCH Mode. If using an i-Vu device or CCN Global Scheduling, use the up arrow to select Time Sched and then press Enter.

or

Click the up arrow and select CCN to control the chiller using a CCN Network Command of "CHIL_S_S".

MODE DESCRIPTIONS

Switch — The chiller will be running 24/7 (no time schedule involved). DO NOT use for the i-Vu device or CCN Global Scheduling.

Time Sched — This mode will allow the user to configure a local schedule and control the chiller by either Local Time Schedule or by setpoint tables 1 or 2. This mode needs to be se- lected if i-Vu will be writing to either a Local (S) or Network

(E) Time Schedule.

NOTE: The i-Vu CCN 4.0 device can only write to Network schedules.

CCN — This will be used when a CCN controller, like a CSM, Translator, or CC will be writing to the chiller's CCN point name CHIL_S_S for starting and stopping the equipment.

Step 3 — Chiller Cooling Set Point Selec- tion — There are several options for controlling the Leaving Chilled Water temperature. For the purpose of having i-Vu able to start stop the chiller through the Time Schedule MODE the chiller's "Cooling Set Point Select" decision needs to be con- figured for SETPOINT 1 using a scrolling marquee or Naviga- tor device.

1.Using a Navigator device, select Operating Modes → SLCT → SP.SE, then enter the password.

2.Click the arrow up and select SETPOINT 1 then push Enter.

Step 4 — Chiller Switch Setup

1.Set the Emergency On/Off Switch (SW2) switch to the On Position.

2.Set the Enable-Off-Remote (SW1) switch to the Enable position. (If Remote is used, external contacts will need to be closed or a jumper needs to be installed on TB-5 no. 9, 10.) The chiller will run off either the Switch, Time Schedule, or CCN Mode (see Mode Descriptions in Step 2).

This completes the configuration decisions needed in a 30XW unit to enable i-Vu device scheduling to control the chiller start/stop.

Step 5 — i-Vu Device Scheduling Setup

CONFIGURING THE i-Vu 4.2 DEVICE (LOCAL AND GLOBAL SCHEDULING)

1.After chiller has been scanned into the database, check the Schedule number. To do this, click on the Schedules Tab → CCN Tab. The CCN Schedule Number needs to be the same number that the user edited in Fig. A or C for local or Fig. B or D for global (see Fig. E).

2.Next, create a Schedule by highlighting the chiller.

3.Click on Schedules → Configure → Add.

4.Then select the type of schedule from the drop down menu.

Example: Select Normal → Weekly and the schedule should look like Fig. F.

5.Configure the schedule.

NOTE: Refer to the i-Vu Installation and Startup manual for more information on creating a schedule in i-Vu.

CONFIGURING THE i-Vu 4.0 DEVICE (GLOBAL SCHEDULING)

1.After chiller has been scanned into the database, check the Schedule number. To do this, expand the Chiller on the left-hand navigation pane → click the on the "Schedule" point → Properties tab → Summary Tab. Enter CCN Global Schedule Number. It needs to be the same number that the user edited in Fig. B or D (see Fig. G).

2.Follow Steps 2 through 5 in the Configuring the i-Vu 4.2 device (Local and Global Scheduling) section.

This completes configuring a 30XW Chiller, i-Vu, and CCN Network Time Schedules.
