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

2. Description
SB-DN-HVAC (MAC01.331) 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 online upgrading

4. Wiring

5. Setting page
The main tab for setting main configurations

6. Setting page 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. (refer to the manual of FCU)

7. Setting page VAV fan voltage output settings
If the fan of FCU is controlled by DC 0-10V, then connected the fan to the DC 0-10V port of HVAC module, and set the fan speed controlling voltage in ‘VAV Fan voltage Setting’. (the voltage of fan speed, you can refer to the manual of FCU)

8. Setting page
AC model settings:
There three different modes for the AC model settings regarding the wiring diagram
a) Normal mode:
the wiring should be like this: relay1=cooling; relay2=heating; relay3=humidity.

9. Setting page AC model settings:
b)complex mode:
if the cooling/heating/humidity/fan/close mode need to use more than one channel to control, you can use complex mode.

10. Air setup page There are two different operation ways.
a) Fully control: the module has ability to control itself, and can be controlled directly from iLife app. the time for compressor, you can refer to the manual of FCU.

11. The temperature can refer to inner sensor or bus sensor, when refer to bus sensor, click “help” button, it would detect the device which can broadcast temperature automatically.
Read sensor every 3s

12. Air setup page
Operation way:
b) Slave control: the module can only be controlled via a DLP, other device (e.g. iLife) can only control HVAC through the DLP.

13. Setting page AC model settings:
example for complex mode: cooling=relay1 on; heating=relay1 & relay2 on.
Attention: Enable simple mode means disable this function

14. Air setup page Host settings
one master HVAC module can control up to 8 slave HVAC modules synchronously.
e.g. below screen shot control the slave HVAC (1-5) synchronously.
Click “Help”, it would detect the HVAC module automatically

15. AC model settings:
c) Force cooling mode:
the wiring should be like this: ModeⅠ=Normal cooling;ModeⅡ=Force cooling channel; Mode Ⅲ=Narmal relay.
Tip: when it is more than 2degree difference between setpoint and current temp, would open the force cooling chanel.

16. Test page 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.

17. Application 1 HVAC in Slave control mode, DLP in Fully control mode.
