Control functions provided as standard by integral components
CZ-RTC6BL remote controller
● Operation-ON/OFF
● Mode selection
● Temperature setting
● Parameter settings
CZ-CAPBC2 Mini seri-para I/O unit
● 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 signal1
● Suction air temperature (TA sensor) output by 4–20 mA signal
● Mode select and/or ON/OFF control
● Fan operation control
● Operation status output/ Alarm output
● Thermostat ON/OFF control
1 Demand control by external BMS cannot be combined with the demand control or target temperature setting accom-
plished by the integrated controller. However, if simultaneous demand control and target temperature setting is needed,
this can only be achieved by using a second (optional) CZ-CAPBC2 interface.
2 Mode select and/or ON/OFF control cannot be combined with fan operation control nor Thermostat ON/OFF control.
However, if simultaneous control of 2 options is needed, this can be achieved by using a second (optional) CZ-CAPBC2
interface. All 3 options cannot be used at the same time.
