Modbus register addesses and info

Note that the product code Swegon SDHW corresponds to the code CWW in the calculation program, followed by the duct size and then the number pipe rows.
SDHW125 = CWW 125-3-2,5
SDHW160 = CWW 160-3-2,5
SDHW200 = CWW 200-3-2,5
SDHW250 = CWW 250-2-2,5
SDHW315 = CWW 315-2-2,5

Note that the product code Swegon SDCW corresponds to the code CWK in the calculation program, followed by the duct size and then the number pipe rows.
SDCW160 = CWK 160-3-2,5
SDCW200 = CWK 200-3-2,5
SDCW250 = CWK 250-3-2,5
SDCW315 = CWK 315-3-2,5
Select “Cooling” from the calculation program!

Airflow can either be extracted from a seperate roof fan, or via by-pass from the AHU (selected models). In both cases without heat recovery.

Central = DCV with one sensor
Local = DCV with more than one

Measurements made according to EN 13141-7.

Heating the supply air is energy consumption consumed when supply air is heated to 21 °C degrees.

Warming of infiltrated air is energy consumption consumed when leakage air (outdoor air coming inside from cracks etc.) is heated to 21 °C

The part of the annual energy that the unit recovers up to room temperature 21 °C

The part of the annual energy that the unit recovers up to selected supply air temperature

Heat exchanger efficiency according to SFS-EN308

SFS-EN13141-7 (including fans)

Calculations are done according Finnish national building regulations part D3, D5:2012 and annex 122 by The Ministry of Environment
