installation can result in a risk of electrical fires, shocks and short circuits. Some states
have specific building codes that govern HVAC systems, including their wiring. Electrical
codes also apply to HVAC wiring and require electricians and builders to use wires and
devices that are compliant and safe.
Safety instructions
we recommend to connect a proper fuse or MCB to the power input
The tightening torque do not exceed 0.4Nm,
Power cable require( Switch)：0.75mm2 to 2.5mm2wire.
Mounting position: DB
Do not make wrong connection on Bus interface, it may cause a damage to the Bus
interface
void the rain or water into module, it will damage this devices
Do not get AC220V voltage into Bus wire , it will damage all of devices in system
check the type of the valve on working voltage , make sure the input voltage is
matched with valve
Type of FAN - check the FAN type, make sure the type is AC or 0-10V .

6. Operation
6.1: commissioning
Method One:
1. Run the HDL-BUS Pro Setup tool.
2. Long press the “programming button” and keep pressing it for 3 seconds until it turns to
a red color.
3. On the software, click the “Address management”, and select
“Modify address (when device button is pressed)” option, it will show a window like
below:
4. click on “Indicate initial address”, then it will show the current subnet/device ID of this
device. to modify the address, fill in the new address, and click the “Modify initial
address ”Click the “+Add” button, the device will be added to “ON-line devices “list.
Method two:
1- Run HDL-bus pro tool
2- Search for the online devices by clicking on search button and the device will be
showed on “online device list”
6.2: software configurations
Normally we need to use a HDL panel with air-conditioning function to control this module,
which means in this manual both the configuration of HDL HVAC module and DLP
air-condition function will be covered.
6.2.1 Basic settings
This tab displays the basic information of this device.

6.2.1.1: Change the address (Subnet / Device ID)
Each HDL-device has subnet and Device ID and each module’s Device ID must be unique
and different from other devices on the same Bus, the subnet ID should be the same as
the HDL-Bus gateway (typically the SB-DN-1IPorHDL-MBUS01IP.431). .
6.2.1.2 Remark
To give a name to the module so you can recognize it from other modules.
6.2.2 Setting
The setting tab is the main page to set all the configuration of this module：-

6.2.2.1 Test the wiring
The wiring test ensures that every relay has been wired correctly and that the system can
operate safely, so before programming an end-user panel, the relay wiring can be tested
here.
Steps: To test the wiring of this module:
a) On the “setting” tab tick the option “model of test relay enable ”to enter the test mode.
b) You can read each relays status by clicking on “read” button
c) Then click on “set “to check and test each relay.
6.2.2.2 Air-condition delay settings
The compressor delay helps to protect the HVAC module from several problems, so it’s
better to set some delay for each compressor.
6.2.2.3 AC model configuration

User Manual
SB-DN-MAC01.331
AC controller –User Manual 7
6.2.2.3.1 Ac model configuration types
There two different modes for the AC model settings regarding the wiring diagram:-
a) Normal Mode: this mode is the default mode and its correspondent to this module’s
default wiring diagram, below is the normal wiring for this module:-
Default wiring: Relay-1=Cooling, Relay-2=Heating, Relay-3=Dehumidification.
b) Complex Mode: this mode is only used when the wiring is not the default wiring so you
can optimize and configure the module according to your own wiring.
For example: suppose that relay#1 is heating, relay#2 is dehumidification and relay#3 is
cooling, in this case we need to make some modification in the Complex mode as the
below figure shows.
Steps: To modify HVAC complex settings according to specific wiring
a) Select Complex mode
b) Double click on “HVAC setting“ table to modify the settings and change the settings in
the pop-up window.
Relay power restore: if this is selected, this module will recover each mode’s status
before power off.
P.s: this function is only assured when the mode is relay and not for HVAC as below
screenshot shows.
2) Compressor protection

User Manual
SB-DN-MAC01.331
AC controller –User Manual 8
If this feature is selected the AC will stop working after period of time“ Compressor work
time” for specified period of time “ compressor protect time “for protection and will restart
working again after that period.
For example: if we set the compressor time as 120minutes and Compressor protect time
as 10minutes, thus after 120m of non-stop using, the compressor will stop for 10m and
restart again automatically.
6.2.2.4: VAV fan voltage settings
This is the DC0-10V fan speed controlling voltage settings, the speed of the fan will
increase when the voltage increased and decrease with the voltage is reduced.
Note: -The parameters could be different from one fan to another, so its better to contact
with the manufacturer, the minimum voltage is 0V and the maximum is 10V.
6.2.3: Air setup
6.2.3.1: Operation type
There are two different operation modes.
