Dehumidification Unit with Air Mixing Function
Type CAC
GEA CAIRfricostar
Control and regulation system:
The switch cabinet is
supplied with the following
main components:
– Consists of a separate switch cabinet for mounting on units or separate installation
(depending in unit size), with all necessary components for control functions, wired
according to VDE specifications. IP55. Electrical connection (via plug or screw
terminals) between control cabinet and unit using factory prepared lines. Electrical
installation for voltage supply, valve mixing control, reheater pump, if necessary
external sensor for the pool water pump and possibly other functions like remote
control inputs to be installed by others. The cabinet is supplied loose depending on
the unit size as a stand alone cabinet or for mounting on the unit;
– Main isolating switch for all pole shut-down of the electrical unit, lockable
– Group fuses for fan and compressor
– Fuses for reheater and PWC pump 230V/N/PE/50Hz (types 015-083) (if necessary
- motor protection by others)
– Control fuses, control transformer 230 V and control voltage supply unit 24V DC for
the digital control
– Control fuse and control supply voltage unit 24V AC for actuators
– Automatic phase controller (option)
– Indoor installation, frost free
Digital control: – Modular automation station built into switch cabinet with deletion-proof software
modules and digital and analogue inputs and outputs, equipped with all control
functions for swimming pool dehumidifier, consisting of:
– Control unit with 32 bit processor in network based, interdisciplinary, free programmable
automation system
– Watchdog function, data buffering (FLASH-ROM), hardware clock
– Interface:1 x CAN (Controller Area Network) as a central bus between control
unit and I/O modules; 1 x LIN (Local Interconnect Network) for additional module
monitoring and configuration functions;1 x CAN for external integration;
– 2 x RS232/RS485, RS232 can operate with a modem
– Optional: Ethernet; USB plug
– As an optional various communication functions can be implemented (e.g: OPC;
LON; MODBUS; OSPA; BACnet ® ). As a native BACnet ® -Building Controller
(B-BC) the system can integrate every BACnet ® third system with little extra
expense or can integrate itself in such a system.
– In and output modules with an integrated microcontroller and memory for recording
a programme specifically designed for the relevant module. Status indicator
for every input or output. CAN provided via top hat-rail bus plug.
