NOTE: Under no circumstance should the unit be started without having read the brochure completely.

30PA electronic control

 

The 

30PA control

 is basically comprised of a 

μ

PC SMALL control 

board, a pGD1 graphic terminal, a TCO user terminal (optional for 
remote control) and sensors.

 

Main functions:

 -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
 -Modi

fi

 cation 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:

 -Modi

fi

 cation 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.

Installation norms

In order to establish the unit's electric power supply (cable inlet, 
calculation of the lead section, protections etc.), refer to:

 

The information supplied in this document (table of technical 
characteristics). 

 

Data plate.

 

The wiring diagram and the legend supplied with the unit. 

 

The electronic control brochure which is supplied with the unit.

 

The regulations and norms in force which regulate the 
installation of air-conditioning units and electric receivers.

The electric power supply of the unit must be sized in accordance 
with the maximum power input by the unit taking into account all 
the options it features (if necessary, refer to the technical brochure).
Verify that electrical power corresponds to the one on the data 
plate and that the voltage remains constant.

Check that the electrical connections are correct and 
tight (an electrical diagram is included with each unit, 
along with its legend).

Note:

 All connections in the site are the responsibility 

of the installer. These connections are always made as 
per the current regulation.

To prevent electrical shocks, make all electrical 
connections before energizing the unit. Check that the 
automatic switch is closed. Omitting this can cause 
personal damage. Make the ground connection before 
any other electrical connection.

The installer must 

fi

 x line protection elements according 

to the e

 ective legislation.
