CLOSE CONTROL UNITS

Pre‑programmed for typical CCU tasks: defrost cycles, fan/compressor sequencing, humidity control, door/pressure switch logic, airflow, fans (on‑off/modulating), secondary sources, free‑cooling, dry‑coolers
Energy efficiency: adaptive defrost, night‑setpoint profiles (“Day & Night”), fan cycling, energy‑saving modes, condenser temp supervision
User accessibility: dual LED displays with icons, hot‑key or tool‑kit for rapid parameter programming, key‑lock, alarm buzzer
Communications & integration: Modbus‑RTU/TTL, optional real‑time clock, HACCP logging, remote display, XWEB monitoring, email/SMS alarm option
Robust built‑in protection: compressor/fan relays up to 20‑30 A, safety control over high/low pressure, overflow, condenser/evaporator temp, defrost termination.
Manage faults in temperature, humidity, fans, compressors, pumps, with logging and remote access.

Designed specifically for Close Control Units – diverse CCU types supported (DX, chilled water, hybrid).
True modularity – expand sensors/outputs as needs evolve.
Built-in BACnet/IP and Modbus for BMS connectivity.
Sophisticated valve and fan control, especially with EC fans and stepper valves.
Rich UI options enhance operator experience and serviceability.
