WCC III Technical Guide 3-192
Caution: DO NOT enter the same output contact on two or
more separate Tenant Utility Lists. Use the “global” feature
if several zones (offi ces) require the same piece of central
equipment to be overridden.
Global Override
Each category of equipment on each screen has a separate
global value which automatically goes ON when that category is
overridden ON.
Tenant Override Screen #1
GL1 goes ON when the lights are overridden ON
GH1 goes ON when the heat is overridden ON
GC1 goes ON when the cooling is overridden ON
Tenant Override Screen #2
GL2 goes ON when the lights are overridden ON
GH2 goes ON when the heat is overridden ON
GC2 goes ON when the cooling is overridden ON
These global values are then used as inputs in a Global Binary
Screen.
Example of Binary Global Screen - Combinatorial Mode
BINARY Global #: _10 name is GB 10
Description: Linux Global On Message #: 1 On
Mode: 1 Combinatorial Off Message #: 2 Off
Value is ON when ANY of the following conditions are met.
GC1 is ON default false
GC2 is ON default false
In Local set this global defaults to Off.
----------------------ALARM-----------------------
Set Condition: None Type: 0 Message: 0
HOME for menu
In this example, assume that air handler #1 (AHU #1) is ON
whenever global binary GB1 is ON.
AHU #1 provides the cooling for the offi ces for the occupants
listed on Tenant Override Screens 1, 2, and 3. When the cooling
is overridden from a tenant listed on screen #1, GC1 will go ON,
causing GB1 to ON, which in turn causes AHU #1 to go on. When
the cooling category is requested from a tenant listed on screen 2,
GC2 goes ON, which will also cause AHU #1 to go ON.
overridden time
The amount of override time remaining will be displayed here in
an hour and minute format. When the override is not active, this
portion of the screen will be blank.
