· Maximum capacity / system: 10 HP (28 kW)
· Maximum piping length: 100 m (120 m equivalent)
· Elevation difference (indoor unit / indoor unit): 4 m
· In / out capacity ratio: 50~100%
· Maximum number of AHU connection kits: 4 units*
· Outdoor temperature range in heating: ‑20 ~ +15 °C
· Available temperature range for the suction air at AHU
connection kit: cool: +18 ~ +32 °C / heat: +16 ~ +30 °C
· The systems is controlled by the suction air (or room
return air) temperature (same as standard indoor unit)
· The discharge air temperature is also controlled to
prevent too‑low air discharge in cooling or too‑high air
discharge in heating (in case of VRF)
· Demand control (forcible thermostat‑OFF control by
operating current)

· Defrost operation signal, Thermo‑ON / OFF states output
· Drain pump control (drain pump and the float switch to
be supplied in local)
· External target temperature setting via indoor / outdoor
signal interface is available with CZ‑CAPBC2 (Ex. 0‑10 V)
· Demand control 40% to 120% (5% steps) by 0‑10 V input
signal
· Connectable with S‑Link system. Special care for
electrical noise may be necessary depending on the
on‑site system
· Fan control signal from the PCB can be used to control
the air flow (high / mid / low and LL for Th‑OFF). Need to
change the fan control circuit wiring at field
*To be simultaneous operation controlled by one remote controller sensor.
