Miscellaneous Options

Trane Communications Interface Module (TCI)

Provides capability to communicate with a Trane ICS^® system.

Compressor Current Sensing (CSM)

This option measures and averages amp draw on each compressor.

Unit Mounted Disconnect

Non-fused, factory installed, and located inside the main control box, this disconnect switch features an external handle that allows the operator to disconnect unit power without having to open the control box door.

Isolators Spring or neoprene-in-shear isolators available for jobsite installation.

Superheat/Sub-Cooling

In place of externally mounted refrigerant gauges, a module can be ordered that will calculate and display on the Human Interface (HI) each circuit’s superheat and subcooling temperatures.

Hot Gas Bypass

Although unnecessary on scroll chillers for comfort applications (due to scroll cycling capabilities), hot gas bypass is still available for applications requiring close temperature control at low load conditions.

Generic Building Automation System (GBAS)

Two modules are available to integrate building automation systems other than Trane. The modules are designed for either 0-5 vdc or 0-10 vdc signals.

Remote Human Interface (RHI) Panel The Remote Human Interface Panel can perform all the same functions as unit mounted Human Interface Panel, with the exception of the Service Mode.

The field installed RHI can monitor and control up to 4 chillers. The RHI is suitable for mounting inside a building, up to 5,000 feet from the unit. The RHI is wired to the IPCB mounted in each chiller with a wire pair communication wiring and 24V control wiring.

Remote Setpoint Potentiometer

Field installed option that allows remote adjustment of the leaving solution setpoint.

Zone Sensor (Chilled Solution Reset)

Field installed zone sensor that allows the leaving chilled solution temperature to be reset by the zone temperature.

Phase/Voltage Monitoring

This device will monitor phase loss, phase reversal on the main power terminal. The module will detect high and low incoming line voltage When these values are out of range, a diagnostic is sent to the Human Interface.

Flow Switch

This field installed option indicates loss of evaporator flow — available for field installation.

Copper Fin Condenser Coils

Copper fins mechanically bonded to seamless copper tubes are available for use in corrosive atmospheres

Electronic Low Ambient Damper(s)

Allows the unit to operate down to 0°F outdoor ambient conditions.

Inter-Processor Communication Bridge (IPCB)

This module provides an amplified and filtered version of the IPC link for connection to a Remote Human Interface (RHI) Panel. Each chiller that is tied into a RHI must have a IPCB installed.

Other Options

In addition to all of these options, Trane can offer in-house design for many ap-plications, including special coil coating.
