6. Chilled Water Reset Outdoor Air Temperatures
Provides for outdoor air temperature reset of the UCP2 front panel chilled water setpoint.
Includes display of outdoor air temperature.
7. Water Pressure Sensors For Evap And Cond System Pressure Less Than 150 Psig.
Includes sensing of the entering and leaving water pressures of the evaporator and condenser,
factory-mounted in the water boxes. The Options module is not required. The following data will
be shown:
~ Entering/leaving evaporator & condenser water pressure (psig)
~ Evaporator and condenser differential water pressure (psid)
~ Evaporator/condenser GPM
~ Evaporator tons (Approximate)
Water Pressure Sensors For Evap And Cond System Greater Than 150 Psig includes
sensing of the differential evaporator and condenser water pressures. The Options module is
included and required. The following data will be shown:
~ Evaporator and condenser differential water pressure (PSID)
~ Evaporator/condenser GPM
~ Evaporator tons (Approximate)
8. Bearing Oil Temperature Sensors
Includes factory installed sensors and safety cutouts (On high temp) to monitor the leaving
bearing oil temperature: Sensor (#1) monitors the journal bearing temperature and Sensor (#2)
monitors the Thrust bearing temperature.
9. Phase Voltage Sensors
Includes factory installed potential transformers in the starter for monitoring/displaying phase
voltage and this provides over/under voltage protection. The following is displayed: Compressor
phase voltage, Kilowatts, Power Factor.
10. Enhanced Condenser Limit
Includes factory installed cond pressure tranducer, piping and wiring.
Provides enhanced high pressure cut-out over cond limit which is standard.
The head relief request relay will energize when cond. limit is approached. The Options module
is included.
11. Discharge Temp Sensor
Includes a factory installed sensor and safety cutout on high compressor discharge temp. Allows
the UCP2 to monitor compressor discharge temperature. When the chiller is selected with hot
gas bypass this sensor is included.
12. Starter By Others
When the starter is being furnished by others, Trane furnishes the Starter module in the UCP2,
and other wiring/components as needed. The starter must be built per Trane starter
specifications.
