INTRODUCTION
Carrierr’s Energy Demand System provides reliable and
automated processes to manage the costs of energy consumption.
Carrier’s Energy Demand System uses wireless devices
incorporating patented Swarm Energy Management algorithms to
create a network of coordinated rooftop units to reduce and
optimize their energy usage. This system creates a wireless
network of rooftop units with Energy Demand Load Controllers
communicating through the Energy Demand Gateway.
Each individual Load Controller can independently decide whether
it should allow its unit to run by a relay that can break the
connection between the rooftop unit and the thermostat. By
communicating energy information through the Gateway, units are
prevented from running simultaneously when it is not necessary,
thereby smoothing out peak demand over time. This method
provides the ability to accomplish Demand Management, Demand
Response, and energy trending over time.
Carrier offers two accessories that, when combined, make up the
Energy Demand System. This technology utilizes Swarm Energy
Managementt methodology as a basis for the operating sequence:
S Energy Management Gateway (Coordinator)
(Model Nos. CRDMNDGW001A00, CRDMNDGW002A00):
This model is packaged with a cellular modem and modem
enclosure, and is the first controller to be attached to a packaged
rooftop unit and powered up. This controller will both
monitor/control the attached rooftop unit, as well as act as a
communicationsgateway back to the Swarm Energy
Management Web Portal, a service provided by REGEN Energy,
Inc..
Table 1 – Kit Voltage Requirements
Kit No. Unit Voltage
CRDMNDGW001A00 208/230/460V
CRDMNDGW002A00 575V
S Energy Demand Load Controller
(Model Nos. CRDMNDMD001A00, CRDMNDMD002A00):
This load controller is installed on the remaining packaged
rooftop units that are to be monitored and controlled.
NOTE: Please ensure you have the correct Installation
Instructions for the given type of controller before continuing.
INSTALLATION CONSIDERATIONS
RTU Checklist
Toward the end of this document, there is a RTU checklist that
must be filled out for every Gateway (Coordinator) installed. The
RTU checklist must be legible. The RTU checklists need to be
scanned and emailed to support@regenenergy.com within 48
hours of the completion of the installation. Providing this
checklist is vital to completing device set--up for operation.
Wiring Diagram
A diagram noting all components and their proper wiring is
provided. (See Fig. 11)
Installation Report
An Installation Report is provided at the end of this document,
where you should record installation notes for each Gateway
(Coordinator), and issues encountered.
Recommended Order of Operation To Install the
Gateway (Coordinator):
1. Determine where to mount each component.
2. Mount the components.
3. Wire all components.
4. Power up and test the Gateway (Coordinator).
5. Fill out the required RTU Installation Checklist.
6. Fill out the Installation Report.
7. Scan and email “RTU Checklist” and “Installation Report”
to fieldops@regenenergy.com within 48 hours of completing device setup.
Preferred Location
(Please note the central location on the rooftop)
Equipment Location:
The first step is to decide which rooftop unit should have the
Gateway (Coordinator). This device should be mounted preferably
in the middle of the rooftop or on a rooftop unit where other
controllers have line of sight access to this rooftop unit. (See Fig.
1.)
Overview Schematic
The components listed below must be installed. Refer to the
diagram in Fig. 2. when deciding where to mount each component
in relation to the rooftop unit.

Suggested Installation Sequence
1. Disable all power to the rooftop unit.
WARNING
!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
Disconnect power before opening unit.
WARNING
!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing, modifying, or servicing system, the main
electrical disconnect switch must be in the OFF position. There
may be more than one disconnect switch. Lock out and tag
switch with a suitable warning label.
2. Open the main cabinet and control board cover
!
CAUTION
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when handling
parts.
3. Determine where each component will be mounted:
S Modem Enclosure: Mounted vertically, on a side of the
cabinet’s exterior
S Gateway (Coordinator): Mounted inside the cabinet,
such that allows access to the keypad and display.
Mounting location examples include, mounting within
the unit control box, on a side wall within the unit, or
any available panel. Ensure the selected mounting location does not cause damage to coils or existing components.
S Antenna & Mounting Base: Mounted on top of the cabi-
net
S Relay: Located inside the cabinet such that it reaches
cooling and heating control lines
S Transformer: Located inside the cabinet such that it can
reach:
a. Transformer primary--side wires will be attached to the
rooftop unit’s load--side leads
b. Transformer secondary--side wires will be attached to
the Gateway (Coordinator) power wires (1 & 2) and
modem power lines (24 & 25). See wiring diagram.
Mount Modem Enclosure:
S Modem enclosure should be mounted vertically on an exterior
fixed panel as close to the top of the cabinet as possible
position that allows the cover to be opened.
S DO NOT MOUNT THE MODEM ENCLOSURE ON ANY
REMOVABLE DOORS
!
CAUTION
ACCESSORY RELIABILITY HAZARD
Failure to follow this caution may result in accessory
component damage.
Installation of Modem Enclosure on moveable doors may
make it difficult or impossible to remove doors. This may
also result in dropping the door and damaging the attached
component or severing wires.
S Choose a side of the cabinet with the least exposure to the sun if
possible.
S Ensure the enclosure’s cables can reach the Gateway
(Coordinator)’s cable inside the cabinet.
S Pass the cables to the cabinet inside the rooftop unit using
existing holes if available, or drill one so the cables can reach the
control panel.
S Secure the cables using the black plastic gland (Hand--tighten).
,ina
Mount Gateway (Coordinator):
S Ensure the selected location for the Gateway (Coordinator)
allows access to see the display & use the keypad. (See Fig.4 )
S Ensure extension wire from the Antenna Mounting Base can
reach the top of the Gateway (Coordinator).
S Securely mount the Gateway (Coordinator) using four of the
Mounting Screws
