CZ-CAPBC2 Mini seri-para I/O unit (advanced version only).
· Easy integration in external AHU control systems and BMS
· Demand control: 40 to 115 % (5 % steps) of nominal current by 0–10 V
input signal*
· Target temperature setting by 0–10 V or 0–140 Ω input signal*
· Mode select or/and ON/OFF control
· Fan operation control
· Operation status output/ Alarm output
· Thermostat ON/OFF control
* Demand control by external BMS cannot be combined with the demand control or target temperature
setting accomplished by the thermostat. However, if simultaneous demand control and target temperature
setting is needed, this can only be achieved by using a second (optional) CZ-CAPBC2 interface.
