2.6.4 Temperature sensors:
The system uses temperature sensors to measure and control the temperatures in the unit. There are three types
of temperature sensors, 5K thermistor (standard), 10K thermistor and RTD (three wires) based on the IOB
channel configurations.
Wiring information (see chiller wiring diagram)
