1. Introduction
This manual introduces the DryGair Smart DG interface, which lets growers
monitor and control their DryGair units – remotely and locally.
Smart DG includes a physical interface that is attached to the unit, as well
as a virtual interface that is accessible via a computer or a mobile device.
Both systems provide growers with full control over their DryGair units,
allowing them to collect climate data and operational data.
The Smart DG feature can be enabled and used on any DryGair
dehumidification unit configured with the c.pCO programmable controller.
Please note that DryGair continuously develops and updates its machines to
maximize their potential. This manual, though entirely up to date when
issued, is subject to changes without notice.

Danger: Electrical Shock Hazard. High voltage is present at points throughout the
unit. Contact with high voltage can result in injury or death. Before performing any
operation related to electricity, open the electric compartment cover, switch off the
Main Power switch and switch off the Circuit Breaker. Doing so ensures no voltage
is present.
Danger: Hot Surface Hazard.The heat exchangers and their pipes, and the
compressor may have a high temperature during unit operation. Do not touch the
compressor and the heat exchanger pipes and coils while the unit is operating.
Verify the unit has cooled down before touching them.

Smart DG Set-Up Procedure
Registering the Units and Creating a Customer Map
DryGair Energies Ltd.
14
5. Smart DG Set-Up Procedure
The following are the basic set up steps for setting-up Smart DG units:
•Registering the Units (section 5.1)
•Activating the Smart-hub License (section 5.2)
•Assigning the Unit Address (section 5.3)
•Connecting the Units to the Internet (section 5.4).
5.1 Registering the Units and Creating a Customer Map
Each project and its units need to be registered in the Smart-hub controller,
enabling the user to monitor, analyze, receive alerts, and control the DryGair
Smart DG units.
To register each of the units in the Smart-hub controller, the distributor
must fill out the following information sheet and send it to the DryGair team.
(see Appendix A).
1. Notify the DryGair team of each Smart-hub serial number.
Note
This process can take 2–3 business days. Therefore, it is advised notifying
ahead of time.
2. Upon receiving the above information, the DryGair team will set up an
account with the customer's details.
3. Once the Smart-hub and the units are connected to the internet network,
the customer will be able to see the units online.
