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.
■■ pGD1 terminal
■■ 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.
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.
