The 30PA control is basically comprised of a μPC SMALL control board, a pGD1 graphic terminal, a TCO user terminal (optional for remote control) and sensors. This control allows the connection to a centralised technical management system by using a speciﬁc BMS card for some of the following communication protocols: Carel, Modbus, LonWorks®, BACnetTM MSTP, Konnex, Modbus TCP/IP, BACnetTM Ethernet, TCP/IP, SNMP V1-2-3, FTP and HTTP. Main functions: - Control in COOLING mode. - Selection of inlet water temperature setpoints for COOLING mode. - Permanent control and optimization of the operating parameters - Safety management. - Timing of the compressor. - Control of condensation and evaporation pressures. - Control of outdoor electronic plug-fan (HEE version). - Control of the circulation pump. - Regulation of the water outlet temperature. - Compensation of the setpoint based on the outdoor temperature. - Timer and weekly programming. - Failure diagnosis and main alarm. pGD1 terminal
This graphic terminal, installed on the electric panel of the machine, allows: - The initial programming of the unit - Modiﬁcation of operating parameters. - Unit ON / OFF. - Selection of the operating mode. - Setting of setpoints. - On-screen display of controlled variables and sensor values measured. - On-screen display of active alarms and historical record of alarms. TCO user terminal (optional for remote control):
The TCO user terminal, for remote control, allows: - Modiﬁcation of some operating parameters. - Unit ON / OFF. - Selection of the operating mode and setting of setpoints. - On-screen display some controlled variables and probe values. - On-screen display of alarms codes.
