General Description
INTRODUCTION OF DMS (DATA MANAGEMENT SERVER)
The DMS is an Internet based device for central management of
Samsung system air-conditioners. It supports LAN & WAN and
operates 24 hours without a separate PC.
ADVANTAGES OF DMS SYSTEM
The DMS provides the following advantages:
 Everyday Device –The DMS is operational all year long
24 hours.
 Independent Operation–The DMS can operate schedule
control, peak power control, and power distribution
without a PC.
Note
In order to run peak power control and power
distribution, relevant controllers need to be installed.
 Internet Control
Web – The DMS has a built-in web server function and
can be accessed from a remote location to operate status
monitoring, control, error history, and schedule setting of
the system air-conditioners.
Using an Upper Level Controller–When a separate upper
level controller (SNET series) is used, a number of DMS can
be controlled with one central management system.
 Data Storage –The DMS has its own database built-in,
therefore, error history, indoor unit installation information,
and power distribution data can be saved and retrieved.
 Large Scale Management–At most 256 indoor units can be
connected to one DMS and therefore, only one DMS can
manage small and medium size buildings.

Main Function
Interface with Upper Level Controller
The DMS receives control data from the upper level controller and sends
the received data to the lower level system.
The upper level controllers of the DMS are the SNET series and the connectible SNET
series are SNET-III, SNET-i and SNET mini. SNET-III is a program that is used by
installing on a PC: SNET-i and SNET mini are touch screen type controllers.
Save Error History
The DMS saves at most 256 cases of error history. If the number of errors exceeds
256, only the latest 256 cases are stored by deleting the oldest error history.
The following errors can be detected by the DMS:
Device
Type
Indoor Unit
Indoor unit communication error
Indoor unit sensor related error
Other errors
Outdoor Unit
Outdoor unit communication error
Pipe inspection error
Outdoor unit sensor related error
Outdoor unit related other errors
Solution Products such as
the Centralized Controller

Select indoor units to receive schedule control
At most
Set indoor unit operation modes
10 events
- Indoor unit On time
- Indoor unit Off time
- Set temperature
- Control mode: Heat, Cool, Dry, Fan, and Auto
- Allow/Disable the use of remote controllers
Both the On time and the Off time can not be set at
the same time and only one must be set.
 Each schedule can be used selectively by using the run schedule/stop schedule order.
At most 256 schedules can be set.
The indoor units can be controlled by the schedule function of
the DMS in at least 1 min. intervals.
Save Integrated Power Distribution Data
Overview
 The DMS calculates and distributes the power consumed by each indoor unit by
receiving the total power usage from the power meter interface modules (SIM) and
taking into account the operation status of the indoor units.
 The DMS saves at most 62 days worth of data. After 62 days, the oldest data is deleted
and the latest data is saved. This data can be viewed through the built-in Web page of
the DMS or by SNET-III.

Time Segmentation
 Time segmentation is used to divide 24 hours into different
sections and to distribute power according to each section.
This function is used when the power consumption fee is
different according to different time slots or when a building is
charged differently depending on the consumption time.
 Time can be divided into 1 section (a), 2 sections (a,b,a), and 3
sections (a,b,c,b,a).
 1 section implies using the whole 24 hours as one section.
The default DMS setting is set to 1 section.
 For 2 sections, 24 hours can be divided as follow:
00 : 00
08 : 30

Execute Peak Power Control and View Status
1) Overview
 The peak power control function is used to minimize instantaneous power usage
by switching the indoor units to Fan mode or turning the indoor units off.
However, since the DMS has priority over user control when using this function,
indoor unit operations by the users are somewhat limited.
  In order to maintain the peak power control, the DMS performs a function that
modulates the indoor unit control by the level signal received from the peak
interface module.
  The peak level consists of 4 steps from 0 to 3 and this level is received from the
peak interface module.

2) Operation Mode
 Peak power control runs in one of the 3 modes:
‘No Control’, ‘Priority Control Mode’, and ‘Circulation Control Mode.’
 No Control:
If the peak power control mode is set to ‘No Control’, peak power control will not run.
The default DMS setting is set to ‘No Control’ mode.
 Priority Control Mode:
In Priority Control Mode, priorities are set for each indoor unit and the indoor units are
controlled according to the priorities set when the peak level is received.
 The operation is as follow:
Input Peak
Peak Power Control Applied Group
Level
Level 0
Peak power control not performed.
Level 1
Only groups with priority set to 1 receive peak control.
Level 2
Only groups with priority set to 1 and 2 receive peak control.
Level 3
Only groups with priorities set to 1, 2, and 3 receive peak control.
 The priority of each indoor unit can be set through the Web or using the upper level
controller of the DMS.
 Circulation Control Mode:
In Circulation Control Mode, indoor units are classified into several groups and each group or
groups are controlled by the peak power function periodically.
 The operation is as follow:
Input Peak
Level
Level 0
Peak Power Control Applied Group
Peak power control not performed.
Level 1
1 group circulation control (Peak control for only 1 group)
Level 2
2 groups circulation control (Peak control for only 2 groups)
Level 3
3 groups circulation control (Peak control for only 3 groups)
 A group or a groups of indoor units are controlled by the peak power function for a set
period of time and the following group or groups are controlled after the set period of
time and so on. The group or groups of indoor units released from peak power function
restore their operation status to before being controlled by the peak power function.

3) Restrictions of indoor unit use
 If operation mode of an indoor unit is Dry, Cool, and Auto, each indoor
unit is converted to Fan mode when peak power control is applied.
 If an indoor unit is operated under Heat, run with one operation among
change to Fan mode, power off, and set temperature change
(16 degree.) It can be set on the upper controller or the Web.
 If an indoor unit which the power is off belongs to a peak power
control group and a user turns on this indoor unit during peak
control, the DMS turns off the indoor unit again.
 If an indoor unit which is operated under Fan mode is a peak
power control applied group and user changes the mode of an
indoor unit that belongs to the applied group to Cool/Heat,
the DMS converts the indoor unit to Fan mode again.
 During peak power control for an indoor unit of peak power control
applied groups, all mode change orders from the upper controller
are constrained to indoor unit ON control, Cool, Auto, and Dry.
 Mode change orders are constrained to indoor unit ON control, Cool,
Auto, and Dry by a Schedule during peak power control and Schedule
Events that is expired during peak power control is nullified.
 If users want mode change to a centralized controller about the
peak power control applied groups and indoor unit ON control,
Cool, Auto, and Dry from a cable/wireless remote control during
peak power control, the DMS checks the condition of the indoor
unit and turns off or converts to the Dry again.
 If a user turns off an indoor unit under peak power control or an
indoor unit is turned off by a Schedule, keep the off status after
finishing peak power control.
4) Other Options
 If Tracking is executed during peak power control, the indoor
unit or the indoor units that was under peak power control
does not restore its previous status.
 Changing the system time of the DMS during peak power
control does not affect the peak control circulation time.
