Domekt Komfovent C4 control board is a AHU (Air Handling Unit) for use in a balanced HVAC system. The C4 is an older standard use from approx. 2010 to 2016.
If you have a unit without a control panel or want to interface the unit with an external automation. ex. Home Assistant, the following data will make that possible.
To make sure the unit works at all, jump the FC-wires together and the unit should start spinning at max. after three seconds. This confirms that the MCU works as expected.
- Domekt Komfovent C4 Modbus Register Document (PDF)
- Domekt Komfovent C4 Plus Modbus Register Document (PDF)
- Domekt Komfovent C4 (buttons) Installation and Operation Manual (PDF)
- Domekt Komfovent C4 (buttons) and C4 Plus (LCD) Installation and Operation Manual (PDF)
Tools
To manually interface with the unit over Modbus, I would recommend trying the trail version of Modbus Poll. You will have a complete control interface and can easily send queries and receive responses from the unit.
Later you can use Home Assistant to build an entire control panel, better than what is provided by the OEM.
Connection
Connect the unit to a computer using the provided RS485/ModBus cable extruding from the top. There is no need to add 820 Ohm 5V pull-up/gnd pull-down or 120 Ohm termination. It works fine as is.
The pin-out is as the following:
| RJ-45 flat cable | Wire color | Function |
|---|---|---|
| Pin 1 | - | Not used |
| Pin 2 | - | Not used |
| Pin 3 | Red | +24VDC |
| Pin 4 | Yellow | RS485 A+ |
| Pin 5 | Green | RS485 B- |
| Pin 6 | White | Gnd |
| Pin 7 | - | Not used |
| Pin 8 | - | Not used |
Modbus settings
To establish a working connection, it's important to match the following connection parameters. A single wrong setting will make the connection not work at all.
| Bits per second/baudrate | 19200 |
| Data bits/word length | 8 |
| Parity | Even |
| Stop bits | 1 |
It is also important to use the correct Modbus ID. It's the identifier on the bus and has to be correct in order for communication to happen with the AHU.
The C4 unit has a different Modbus ID than later models, so make sure to double check. Either of the following will work with only one unit on the Modbus line.
| Modbus ID | 20 (specific C4 identification address) 254 (common identification address) |
Register list
The C4 unit uses the following Modbus data register functions to read and write data.
A CR2032 battery keeps the registers concurrent when the unit is unplugged, ex. the time and date. Needs replacing after 8 years.
The unit will respond 01 Illegal register or 01 Illegal data register if you are trying to access something that does not exist. If you receive Timeout responses, make sure you use Modbus ID 20, cabling is correct, and the unit is plugged into the mains.
| Description | Modbus protocol | Function description | Unit properties |
|---|---|---|---|
| Read data | Function code 03 | Read Holding Registers / analog output holding registers | Operation status, temperatures, fans speed, and etc. |
| Write data single register | Function code 06 | Preset Single Register / analog output holding register | Turn on/off unit, set temperature, change auto/manual mode |
| Write multiple data registers | Function code 16 | Preset Multiple Registers / two analog output holding registers | Set multiple individual registers at once, similar to 06 |
Controller registers available on the C4 unit. When manually inquiring the unit, use the actual register address. This is because Domekt offsets the register address by add 9000 and subtract -1, ex. register address 1000 => 99999.
- EC = Stepper type fan motor, digitally controlled - DIP switch 3 set to ON
- AC = Regular alternating current type motor, transformer controlled - DIP switch 3 set to OFF
