7 Technical description
7.1
Features
The product uses temperature differential and hysteresis to manage the capacity of
the chiller in single or multistage application. The controller has a PGD1 or PGD1 LCD
display.
The user can select between Cool, Heat, or Electric Heat (EH) mode
operation in single or multistage configuration.
The system is internally grounded with isolation between inputs and outputs.
Additionally, the output relays offer double isolation so that different voltages can be
used for groups of relays.
The system uses various sensor types for measuring analog temperatures and pressures.
For temperature measurements, the system uses NTC type 10 kΩ @ 77°F (25°C)
thermistors. Pressure transducers are ratiometric 0 psi (0 bar) ... 650 psi (44.82 bar)
(45 bar) range for both suction and discharge monitoring.
Available options:
• Compressor current monitoring
• Pump current monitoring (SW and CW)
• Condenser freeze protection
• Electric heat
• EEV control
• Pressure transducers
• Load shedding input signal
