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	--	--	--

	up	W	increase the set-point temperature of 0.5 °C
	down	W	decrease the set-point temperature of 0.5 °C
<n>.temp	<val>	R	the measured temperature from the target is <val> (expressed in °C/10)
fan.speed <n>.fan.speed <type>.fan.speed	low mid high	R	the fan speed of the target is set to the specified value[Note 1]
		W	set the fan speed to the specified value
	switch	W	switch the fan speed cycling among the values low, mid, and high
	unknown	R	the fan speed is not known

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 Interface

UISET Actions

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.
