Hardware to bacnet/Ip - Home Automation

Hii,

I have a question regarding the AC unit interface with home automation. I have in the AC unit 5 cables for the control as follow :
- On/Off.
- Fan High.
- Fan Med.
- Fan Low.
- Cooling.
I want to control these options via Bacnet/IP but I have only a hardware connection, so can you please advise any controller who can convert the hardware command to BACnet/IP.
