Options
LonTalk/Tracer Summit Interface
LonTalk (LCI-C) or Tracer Summit communications capabilities are available, with communication
link via single twisted-pair wiring to factory-installed, tested communication board.
Low Ambient Fan Control - Two Speed (RTUD only)
The fan control shall provide for the first fan to be a two speed fan and the microprocessor can be
programmed to control the low and high speed of that fan.
Low Ambient Fan Control - Variable Speed (RTUD only)
The fan control shall operate a fixed speed fan or a single inverter driven fan and the controls
include the enabling and speed command signals to the variable speed inverter.
Motor Current Analog Output
Control system indicates the active chiller percent of full run load amps, based on a 0–10 Vdc.
Power Meter
Tracks energy consumption (compressors only) with kWh meter.
Programmable Relays
Predefined, factory-installed, programmable relays allow the operator to select four relay outputs.
Available outputs are: Alarm-Latching, Alarm-Auto Reset, General Alarm, Warning, Chiller Limit
Mode, Compressor Running, Head Pressure Relief Request, and Tracer Control.
Time of Day Scheduling
Time of day scheduling capabilities are available for scheduling single chiller applications through
Trance CH530 panel (without the need for building automation system-BAS). This feature allows
the user to set up to 10 events in a 7 day time period.
Trane Air-Cooled Remote Condenser Options (RTUD only)
Low Ambient
Allows the condenser to start and operate down to 14°F and up to 125°F (-10°C-52°C).
Condenser Voltage
Voltages available 208-230, 460, and 575.
CompleteCoat Condenser Coil
Allows for the operation in coastal environments. This option includes condenser coil box coating
that resists bi-metallic corrosion.
