Lua script on SE8350 and Intesis AC interface - integration to control a Daikin VRV indoor unit.

[Lightman]

Hi Team,

I need assistance to make adjustments to a Lua script that is currently being used to control a Daikin vrv indoor unit system using an ASP and Daikin master station. This system is being used in a hotel room setup and includes a room lighting logic. The lighting logic uses a wireless door contact and a wired ceiling PIR. The conditions are:

1. That the lights immediately switch on when the door is opened and the room is occupied and will only go off if the door is opened and the room is left unoccupied for 15min.

2. when the room goes unoccupied, the aircon setpoint should change to 24 degrees Celsius and fan speed should change to low. 

3. If the room goes occupied again, the temp setpoint should change back to what the occupied set point was before it changed to 24 degrees and a similar action should happen for the fan speed.

Currently the SE8350 controller in the room is sending commands to the Daikin via the ASP. The systems works ok except for when there is power failure and the network switch between the Daikin and the ASP. 

We want to send these commands locally within the room between the SE8000 and the Indoor VRV unit.

I have attached the working Lua script, the system design and Intesis BACnet guide.
