9.11.9 Lighting Bypass Inputs
The application provides two bypass inputs:
• Bypass ON - When ON, this input will force the digital
lighting output ON.
• Bypass OFF - When ON, this input will force the digital
lighting output OFF.
9.11.10 Demand Shed Behavior
The application provides a demand shed input. When this
input is ON, the Lighting Application turns the lighting output
OFF. Generally, this input is connected to the Demand
Control application.
If the lighting application is configured to use dimming, the
lighting output is set to the “Dim Shed %” value while a shed
event is active.
9.12 Global Data
The Global Data application is the central location for
commonly used data values and limited data calculations
such as degree days and seasonal determination.
The following are the global data outputs:
• SUMMER WINTER - Summer/Winter indication output.
• COOLING DEGREE DAY - Indicates the current cooling
degree day calculation based on the “integration”
method. The calculation starts over at midnight for the
new day and the previous day's calculation is logged.
• HEATING DEGREE DAY - Indicates the current heating
degree day calculation based on the “integration”
method. The calculation starts over at midnight for the
new day and the previous day's calculation is logged.
• ENTHALPHY DEGREE DAY - Indicates the current
enthalpy day calculation based on the “integration”
method. The calculation starts over at midnight for the
new day and the previous day's calculation is logged.
• DAY SCHED OUT - Indicates current day of week or
holiday.
The Global Data function allows property information to be
shared in a mixed site that contains both E2 and E2 Enhanced
Controllers and Supervisory Controllers.
9.12.1 Location From
Sunrise and sunset times are calculated based on either zip
code or latitude/longitude. If US Zip Code is chosen in the
Unit Location From field, enter the zip code in which the
controller is located. If outside the United States, choose Lat/
Long and enter the latitude and longitude values in which the
controller is located. Once a value has been chosen, the
controller is able to calculate the sunrise and sunset times.
The Sunset output will turn ON at sunset, and OFF at sunrise
and can be connected to a lighting circuit.
9.12.2 Sundown
Sundown is an output that calculates when the sun sets
based on latitude and longitude, and is ON when the sun sets.
(When a Lighting Schedule is configured to use Sundown
information, the Lighting Schedule application automatically
connects to the Sundown output).
9.13 HVAC Control
The HVAC control application controls HVAC equipment,
rooftop units, or air handlers.
The number of AHU applications allowed is based on the total
number of applications allowed on the device. The AHU
application provides basic functionality to control a typical
packaged HVAC unit. The packaged HVAC units have up to
four stages of heating and cooling and may have a fresh air
damper installed to allow free-air cooling (economization)
when conditions permit.
9.13.1 Active Setpoint Determination
The active setpoint used by the heating and cooling logic is
selected from the following setpoint inputs:
• SUMMER HEAT OCC - This field is the setpoint that is
used for heating control during summer occupied mode.
If this AHU has been assigned to a Zone application, this
input is automatically be defined so that the Zone
application supplies the setpoint value. You do not need
to change this definition.
• SUMMER HEAT UOC - This field is the setpoint that is
used for heating control during Summer Unoccupied
mode. If this AHU has been assigned to a Zone
application, this input is automatically defined so that the
Zone application supplies the setpoint value. You do not
need to change this definition.
NOTE
NOTE: The AHU application provides support for
Constant Air Volume (CAV) systems only. The
Variable Air Volume (VAV) systems are not
supported.
