Daikinrc
Daikin air-conditioning systems in combination with the intelligent Touch Controller (iTC) or the intelligent Touch Manager (iTM) allow for remote control and supervision, via Ethernet communication, of the whole framework.
This driver is compatible with iTC and iTM modules respectively compliant with the DCS007A51 and DCM007A51 http protocol.

Daikin Configuration and discovery
All units must be connected to the same LAN of the HSYCO Server. When the DAIKINRC I/O Server starts, and then periodically every 30 to 60 seconds, a discovery request is sent to the LAN. New units responding to the discovery request will start to be polled by the I/O Server and become online.
System Architecture
The system can handle devices of the following typologies: HRV, VRV, D3Dio, and D3Di. The driver allows to address each device individually, or grouped by type, or as a whole system. The following image shows a simple system configuration:
Depending on the type of the device, different settings can be monitored and/or set.
The following table shows the items that can be monitored (M) and set (S) for each type:
| Item | VRV | HRV | D3Dio | D3Di |
|---|---|---|---|---|
| Power status | M/S | M/S | M/S | M |
| Operation mode | M/S | -- | -- | -- |
| Ventilation modes and level | -- | M/S | -- | -- |
| Suction temperature | M | -- | -- | -- |
| Set-point temperature | M/S | -- | -- | -- |
| Fan speed and direction | M/S | -- | -- | -- |
| Filter signal | M/S | -- | -- | -- |
| Malfunction status and code | M | M | M | M |
HSYCO Configuration
Add a DAIKIN I/O Server in the I/O Servers section of the Settings and set its parameters:
Communication
- IP Address: IP address set on the iTC/iTM
- IP Port: TCP/IP port set on the iTC/iTM.
High Availability
- Shutdown when inactive: defaults to true.

- Note 1
Events concerning a group of devices (i.e. broadcast and type-related events) assume the value of the last updated device in the group. That is, for instance, if all VRVs are in operation mode “cool” and only one of them is changed to “heat” then the event <ioserver_id>.vrv.opmode = heat will trigger.

USER Commands
The Daikin I/O Server supports a few system commands to be inserted within the Web interface. The controls are directly supported as ordinary user objects, by setting the name and param fields according to the corresponding datapoints table.
For instance, setting the name of a user object to “dkn.1.power” and its param field to “on”, will result in having a switch for the device with address 1. Naming it “dkn.1.opmode” with a valid working mode as param (e.g. “heat” or “cold”) will result in a button for setting the mode of the device.
