Installation

Power supply should adopt an independent transformer source and should not be shared with other controllers or converters so
as to prevent short circuit and device burn-out.

Allow other TCP client devices to Read/Write data. TCP/IP port number is defaulted to 502 and configurable otherwise.

MODBUS RTU/ASCII communication port is configurable to be either RS-485 port or RS-232 as it shares the same system
resource.

MODBUS RTU/ASCII communication port can connect, in field application, to an indefinite number of devices, depending on
device characteristics, data quantity and data format. An RS-232 network can allow only one standard RS-232 device
connection. In case of an additional device connection, a PC-ME11 or PC-MP11 protocol converter should be added in.

The PC-ME11 is a master device in MODBUS RTU/ASCII communication, therefore it can only integrate with and connect to a
slave device. Every slave device on the same network has to have the same communication speed and data format.

MODBUS RS-485 communication port can integrate an indefinite number of connected slave devices, depending on device
characteristics, data quantity and data format. The load should be estimated by professional personnel, otherwise it will cause
system overload and result in instability.

MODBUS RS-485 network should be properly terminated with 120Ω terminal resistors to avoid signal fading. Devices to be
integrated within the RS-485 network should be ready for MODBUS RS-485 communication, specifically running as the standard
MODBUS RTU or MODBUS ASCII Slave format.

Installation

Power supplies should be configured on a one-to-one basis and do share the same power supply with other controllers or power
adapters.

The MODBUS communication port is can be either RS-485 port or RS-232 only as it shares the same system resource. Do not
connect to two types of devices at the same time.

MODBUS RTU/ASCII communication port can connect, in field application, to an indefinite number of devices, depending on
device characteristics, data quantity and data format. Generally, an RS-485 network can accommodate a maximum of 32
standard devices. In case of more connected devices, a repeater should be added in; An RS-232 network can allow only one
standard RS-232 device connection. In case of an additional device connection, a PC-MP11 protocol converter should be added
in.

The MODBUS communication port uses master mode to connect to slave devices. Slave devices on the same network has to
use the same communication speed and data format.

MODBUS network should be properly terminated with 120Ω terminal resistors to avoid signal fading.

Devices to be integrated within the network should be ready for MODBUS RS-485 or RS-232 communication, specifically
running as the standard MODBUS RTU or MODBUS ASCII Slave format for the data.

Installation Tips

When the controller shares a power adapter with a ratio control valve, please take care not to connect their common wire
(negative) in the wrong way, or damage might happen to the equipment.

When wiring for fan start/stop, it is recommended to use 1.25mm2 control wire in independent piping. Do not put in the same piping
with other wires to prevent mutual interference.

Apart from fan start/stop control points, it is recommended to use AWG 18 twisted pair shielded cables for other wires and use EMT
to get the best control effects.

Network wiring should be done in a daisy-chain manner (as shown in Network Architecture Diagram). Do not use a junction box
or parallel connection. The beginning and terminal ends of the wires should connect to a 120Ω termination resistor.

This controller is an all-in-one controller. Please do not install the panel and the base plate separately to avoid interference to
the controller and the network and cause control malfunctions.

To display the time or not can be determined by internal parameters of the DT4211B. The time has to be synchronized by the upper
layer control system.

When installing the panel a screwdriver is needed to secure the metal plate in place first and then fit the controller in and push
downward to secure it. When removing the unit, follow the instructions in reverse order.

AI input signals are 0~10 VDC or 4~20 mA selectable. The signal selection jumper at t he back of panel needs to be switched to
do so.

When connecting the network, each DT4211B has to be set with a unique network address by way of button inputs. Please refer to
the technical manual that came with your device for the way to set the address and other technical data.

points in total Backlight function
Installation
When the controller shares a power adapter with a ratio control valve, please take care not to connect their common wire

(negative) in the wrong way, or damage might happen to the equipment.
When wiring for fan start/stop, it is recommended to use 1.25mm2 control wire in independent piping. Do not put in the same piping

with other wires to prevent mutual interference.
Apart from fan start/stop control points, it is recommended to use AWG 22 twisted pair shielded cables for other wires and use EMT

to get the best control effects.
Network wiring should be done in a daisy-chain manner (as shown in Network Architecture Diagram). Do not use a junction box

or parallel connection. The beginning and terminal ends of the wires should connect to a 120Ω termination resistor.
This controller is an all-in-one controller. Please do not install the panel and the base plate separately to avoid interference to the

controller and the network and cause control malfunctions.
To display the time or not can be determined by internal parameters of the DT4211M. The time has to be synchronized by the upper

layer control system.
When installing the panel a screwdriver is needed to secure the metal plate in place first and then fit the controller in and push

downward to secure it. When removing the unit, follow the instructions in reverse order.

AI input signals are 0~10 VDC selectable. The signal selection jumper at the back of panel needs to be switched to do so.

When connecting the network, each DT4211M has to be set with a unique network address by way of button inputs. Please refer to
the technical manual that came with your device for the way to set the address and other technical data.

Wiring

The EIM..M can use the exclusive 24 VAC or 24 VDC power supply and it is forbidden to share the same power supply with other
devices.

The RS-485 network cable has to be run in a daisy-chain manner. Do not use a tree or star topology. Both ends of the network
should be terminated with a 120Ω termination resistor. The total length of the network cables cannot exceed 1,200 meters.

The input/output control line of the EIM..M is recommended to use #AWG 22 shielded cables to get the best control quality.

The BO Manual/Auto switch of the EIM..M has to be set to Auto to receive commands. When manual tests are complete, it has to
be set back to Auto.
The binary outputs on the EIM..M are 7 A/250 VAC dry contacts. Do not use electromechanical equipment exceeding this capacity.
Should it be exceeded, an auxiliary relay or electromagnetic switch is needed.

I/O Expansion Module
EIMnet Communications
Protocol Module EIMXM
Application
The EIMXM is a remote control unit that follows the MODBUS RTU communication
format. It is primarily used for integrated expansion of WC, GC, DAC, DSC and other
series of products. The major application is equipment integration of inverters, two-wire
sensors, multimeters and the like that follow the MODBUS RTU format. The EIMXM has
a 32-bit high-speed microprocessor. When coupled with Delta Electronics products,
there would be various combinations to complement the various integration needs.
Through connection with the EIMnet port of the controller, it can directly convert the
BI/AI/BO/AO/PI on the EIM to the BI/AI/BO/AO/PI on the DAC so that control
procedures can be completed on the same DAC to ensure the feature of independent
operation to increase completeness of the programs and even reduce the overall cost.
Product Features

EIMnet communication port that follows MODBUS RTU communication format, uses RS-485 transmission and the distance can
reach 1,200 meters

Each module has an Address DIP switch to set addresses in the range of 1~24, but each controller is recommended to connect to
one EIMXM only.

Each module has communication and equipment status indicators to facilitate onsite engineers getting hold of system op eration
status and performing troubleshooting in real time.

When coupled with a Delta Electronics WC, GC, DAC or DSC microcomputer programmable controller, it can adjust points flexibly
as well as reduce equipment cost and increase the completeness of the control programs.

Through connection with the EIMnet of a DAC, it can directly convert the BI/AI/BO/AO soft points on the EIM to BI/AI/BO/AO on the
controller without complex setting and conversion.

Each module can convert a maximum of BI*32 or AI*32 or BO*16 or AO*16, that is also the physical hard points 4 EIM..M devices
can connect to. Please be noted that points over the amount cannot be mapped. And the amount of EIM..M devices EIMXM
corresponds to will take up the total amount of the EIMnet communication connections. This is to be noted in its application.

When connected to a Delta Electronics CP2000 inverter, please choose the EIMDM inverter specific module to save editing work on
the corresponding points.

Sliding track design that saves space with ease of installation. The terminal connectors are pluggable by design with
communication and equipment status indicators for easy troubleshooting.

RS-232 communication port with communication parameters modifiable through AD-Linker coupled with the specific EIMXM editor

Analog data reads and writes support floating point, double-precision floating point, long integer, BCD encoding and many
nonstandard numeric value forms

Each analog read/write command supports one add/minus/multiply/divide operation for use in numeric shift or multiplier
adjustment.

Wiring

When the power supply and the FCU use the same power source, please confirm if the voltage is correct first.

Please secure the controller to the ceiling that is easy to examine and repair next to the FCU . Do not secure it to the FCU to avoid
controller malfunctioning.

Please use 2-wire AWG #22 twisted pair shielded cable to wire the cable between two DSx1150B controllers in a daisy-chain
manner (refer to the wiring and architecture diagrams). Do not use a junction box or parallel connection. When wiring is
conducted, please take note to make sure the electrical polarity is consistent, or the network might not connect.

All network cables should be in independent EMT and must keep some distance from power lines to avoid interference and
ensure good network communication quality.

This controller has a 2/3 piping iced/hot water control valve design. When used in 2 piping electric valve control scenarios, just
connect the electric valve control point to OPEN.

The juncture of the electric valve and the fan should be connected to the ground wire of the power source. Incorrectly wired
equipment will not operate normally.

Application

When the power supply and the FCU use the same power source, the first step is to confirm if the voltage is correct first. The power
line, fan 3-speed control line and electric valve control line should use control lines in the range 0.5~1.25mm 2. Too big a wire diameter
will cause damage to the controller terminator and too small a wire diameter might not withstand the current of the equipment.

The DFC is applicable in central air conditioning 2 piping or 4 piping fan coils and direct expansion air conditioners. Setting of internal
DFC parameters is needed for different forms of control functions. Please refer to technical manuals for more information.

Please use 2-wire AWG #22 twisted pair shielded cable to wire the cable between two DFC controllers in a daisy-chain manner (refer
to the wiring and architecture diagrams). Do not use a junction box or parallel connection. When wiring is conducted, please take note
to make sure the electrical polarity is consistent, or the network might not connect.

Please use 4-wire AWG #22 twisted pair shielded cables in wiring the cable between NFC32V and DFC controllers, in which two wires
act as power lines for the NFC32V.

All network cables should be in independent EMT and must keep some distance from power lines to avoid interference and ensure
good network communication quality.

Binary inputs must be the dry contacts. If equipment like a mobile sensor that needs external power is used, please provide a
power source for it.

The DFC can control 2 or piping electric iced/hot water valves. When used in 2 piping valve control scenarios, just connect the
electric valve to OPEN.

The juncture of the electric valve and the fan should be connected to the ground wire of the power source. Incorrectly wired
equipment will not operate normally.

The DFC is equipped with an 5A fuse as factory default. When equipment needing more than 5A of current is used, an auxiliary relay is
needed, or it might cause the fuse to blow.

RF Network FCU Controller DFR…A
Application
The DFR...A series RF Network FCU Controller is a multifunction,
economical, stand-alone controller. Through RF communication, it can
connect a maximum of 16 FCU controllers to a PF series protocol
converter to form a wireless local area network to realize central
management of equipment in different locations. It can also connect to a
panel to perform single machine or group control. Through HMI operation
the user can change the action of a group or individual DFR controllers.
Examples are fan on/off, AC mode, fan speed, temperature setup,
shutdown timer and scheduled on/off actions. It can also monitor DFR
statuses like onsite temperature, system operation, fan speed, malfunction
alarm, and so on. This controller is applicable for use in office buildings,
hotels, shopping malls, factories, or energy-saving improvement projects.
Product Features

output control points

AC operating modes of cooling, heating and fan. Additional energy saving operating function to save energy and increase
comfort.

Scheduled on/off functions. Additionally a quick 0~24 hour timed shutdown function that is suitable for office occasions.

When connected, it has network time auto synchronization function. It can accept time adjustment from the monitoring network
to make all controllers in the system have the same time.

Delayed automatic recovery function by order of power outage. If the unit was on before the outage, automatic start will be
delayed according to the address sequence when power comes back on.

Can connect to monitor and control points, fan on/off, AC mode, fan speed, indoor and set temperatures, timed shutdown and
scheduled on/off, water leak, fire alarm, abnormal temperature alarm and others. Parameters can be stored when power for the
controller is cut off. When power comes back on normally, it will be restarted to operate according to the stored memory data.

Wiring

When the power supply and the FCU use the same power source, please confirm if the voltage is correct first. The power line, fan
3-speed control line and electric valve control line should use control lines in the range 0.5~1.25mm2. Too big a wire diameter will
cause damage to the controller terminator and too small a wire diameter might not withstand the current of the equipment.

The DFR is applicable in central air conditioning 2 piping or 4 piping fan coils and direct expansion air conditioners. Please refer to
technical manuals for more information.

Please use 4-wire AWG #22 twisted pair shielded cables to wire the communication line between DFR and MFC/NFC control
panels.

All network cables should be in independent EMT and must keep some distance from power lines to avoid interference and ensure
good network communication quality.

The DFR uses RF communications so care has to be taken regarding partition obstruction and interference when installing it. T he
radio frequencies the DFR uses can go through 1-2 light partitions or 1 concrete wall, but cannot go through a metal compartment
(clean room compartment or steel/aluminum compartment). In an open, unobstructed and interference-free area, it can transmit
around 100 meters.

Binary inputs must be the dry contacts. If equipment like a mobile sensor that needs external power is used, please provide a power
source for it.

The DFR can control 2 or
electric valve to OPEN.

The juncture of the electric valve and the fan should be connected to the ground wire of the power source. Incorrectly wired
equipment will not operate normally.

When the DFR is used in a local area network, a different channel and address has to be set. It uses DIP switches to set the
channel from 0~15 (16 in total) and the network address from 0~15 (16 in total) in a binary manner. Controllers sharing the s ame
channel cannot use the same address.

The DFR is equipped with an 5A fuse as factory default. When equipment needing more than 5A of current is used, an auxiliary
relay is needed, or it might cause the fuse to blow.
