VENTILATION
System example with AHU connection kit MAH4M and Mini ECOi outdoor unit.
· AHU connection kit in an IP 65 casing, contains PCBs and
terminal connections mounted inside
· Select the size of the expansion valve pack based on the
capacity
· Direct Modbus communication with a built‑in Modbus
S‑Link interface
· The heat exchanger, fan, and fan motor to be mounted in
the AHU are field‑supplied
2 options for external BMS connection
AHU connection kit +
expansion valve pack
Modbus: RS485
Other BMS: Hardwired
Mini ECOi or ECOi EX
2-Pipe outdoor unit
Air handling unit
(AHU)
Demand control on the outdoor unit managed by external 0-10 V signal.
0-10 V control
With 0‑10 V demand control, the outdoor unit capacity can be adjusted in each 5% demand step. Temperature set control
(default discharge temperature control) is also available in each 0,5 K step.
