Options
Low Ambient Option
The low ambient option provides special control logic, oil coolers, and variable frequency drives
on the condenser fan circuits to permit low temperature startup and operation down to 0°F (-18°C).
High Ambient Option
The high ambient option consists of special control logic and oil coolers to permit high ambient
(up to 125°F [51°C]) operation.This option offers the best performance when coupled with the high
efficiency performance option.
Remote Evaporator
The remote evaporator option is available on the RTAC 140-250 ton units.This option provides a
pre-engineered method of installing the evaporator and all related components indoors. Remote
evaporator installations allow the water loop to remain indoors to prevent freezing, thus
eliminating the addition of glycol to the system and the resulting performance degradation. Please
contact yourTrane Sales Representative for split system design guidelines found in Engineering
Bulletin RLC-PRB014-EN.
Electrical Options
Circuit Breaker
A HACR rated molded case capacity circuit breaker (UL approved) is available.The circuit breaker
can also be used to disconnect the chiller from main power with a through the door handle and
comes pre-wired from the factory with terminal block power connections.The external operator
handle is lockable.
Non-Fused Power Disconnect Switch
The non-fused molded case disconnect switch (UL approved) is used to disconnect the chiller from
main power and comes pre-wired from the factory with terminal block power connections.The
external operator handle is lockable.
Single/Dual Incoming Power Line Connection
Single or dual points of termination are available for incoming power line connections*. Units with
3-4 compressors must order circuit breakers with the single point connection option.*Some
restrictions may apply.
Wye-Delta Compressor Start Type
This option provides a reduced inrush starter. Wye-Delta starters are standard on 200-230 volt
machines.
Control Options
BACnet Communications Interface
Allows the user to easily interface with BACnet via a single twisted pair wiring to a factory installed
and tested communication board.
LonTalk (LCI-C) Communications Interface
Provides the LonMark chiller profile inputs/outputs for use with a generic building automation
system.
Remote Input Options
Permits remote chilled liquid setpoint, remote current limit setpoint, or both by accepting a 4-20
mA or 2-10 Vdc analog signal.
