Daikin

Daikin air-conditioning systems in combination with the intelligent Touch Controller (iTC) allow for remote control and supervision, via Ethernet communication, of the whole framework.

This driver is compatible with the intelligent Touch Controller DCS601C51 and complies with the DCS007A51 http open protocol.

 The HTTP license provide by Daikin is required.

Communication

Use an Ethernet straight cable to connect the iTC to the network.

In order to be able to control the system with HSYCO some initial configuration is needed:

• From the main screen, press the S button:

• Select System:

• Select Network and press Execute:

• Configure the network settings:

• Go back to the System Settings page, select Web Server and press Execute:

• Set the port number of the Web server:

System Architecture

The system can handle up to 64 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

Options

ID	Default	Values	Description
gui	true	true	enable support for the UI object, UISET actions and USER commands
		false	disable UI support
startupevents	false	true	generate IO events also during the driver’s start-up phase
		false	start generating events only after HSYCO is aligned with the current status of the system
pollinterval	20	n > 0	the data acquisition interval, in seconds

Datapoints

ID	Value	R/W	Description
connection	online	R	connection established to the device
	offline	R	HSYCO can’t connect to the device
power	0	R	the whole system is off
		W	turn all devices off
	1	R	at least one device is on
	W	turn all devices off

User Interface

UISET Actions

ID	Attribute	Set to

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.
