1. SB-DN-HVAC (MAC01.331)
Air-Condition controller

2. Description
SB-DN-HVAC (MAC01.31) module designed to control centralized HVAC or FCU, through HDL control panel with air-conditioning function, depending on the preset ,current temperature and with the built-in algorithm

3. Main functions
It has three relays to control modes ( cooling, heating and dehumidification)
Three relays to control fun speed ( low, medium and high)
Built-in controlling algorithm which can control the air-conditioner smartly.
Can be connected up to 4 PCS of DS18B20( Digital Temperature Sensor, supplied by HDL)
One master module can control about 8 slave modules.
Support s online upgrading

4. Wiring

5. Settings
the main tab for setting main configurations

6. Test settings:
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.

7. 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.

8. AC model settings:
There two different modes for the AC model settings regarding the wiring diagram
a) normal mode b)complex mode

9. 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 when the voltage is reduced.

10. Air setup
This tab focuses on operation mode, host and temperature settings

11. There are two different operation modes.
a) Fully control b) Slave control

12. Temperature settings
It can support up to 4-pieces of digital temperature sensors(supplied by HDL).
Temperature broadcasting mode:-
a) refer to inside sensor b)refer to outside sensor

13. Host settings
one master HVAC module can host and control about 8 slave modules.

14. model and statue
