unit must be equipped with an optional InterProcessor Communications Bridge (IPCB).The RHI can be located up to 1,000 feet from the unit. A single RHI can be used to monitor and control up to 4 rooftops, each containing an IPCB.

Human Interface Panel Main Menu

STATUS — used to monitor all temperatures, pressures, humidities, setpoints, input and output status.The

CUSTOM key allows the user to customize a status report—consisting of up to (4) screens of the data available in the main Status menu.

SET POINTS — used to edit all factory preset Default setpoints

DIAGNOSTICS — used to review active and historical lists of diagnostic conditions. A total of 49 different diagnostics can be read at the Human Interface Panel and the last 20 diagnostics can be held in a active history buffer log at the Human Interface Panel.

SETUP — Control parameters, sensor selections, setpoint source selections, output definitions, and numerous other points can be edited in this menu. All points have factory preset values so unnecessary editing is kept to a minimum.

CONFIGURATION — Preset with the proper configuration for the unit as it ships from the factory, this information would be edited only if certain features were physically added or deleted from the unit. For example, if a field supplied Trane Communication Interface (TCI) module or Ventilation Override Module was added to the unLitorder it in the field, the unit configuration would need to be edited to reflect that feature.

SERVICE — used to selectively control outputs (for compressors, fans, damper position, etc.) for servicing or troubleshooting the unit.This menu is accessible only at the unit-mounted Human Interface Panel.

Generic Building Automation System odule (GBAS)

The Generic Building Automation System Module (GBAS) is used to

provide broad control capabilities for building automation systems other than theTrane’sTracer® system. A field provided potentiometer or a 0-5 vdc signal can be applied to any of the inputs of the GBAS to provide:

a

Analog Inputs — 4 Analog inputs that can be configured to be any of the following:

(1)Occupied Zone Cooling

(2)Unoccupied Zone Cooling

(3)Occupied Zone Heating

(4)Unoccupied Zone Heating

(5)SA Cooling Setpoint

(6)SA Heating Setpoint

(7)Space Static Pressure Setpoint

(8)SA Static Pressure Setpoint

b

Binary Outputs — each of the five (5) relay outputs can be mapped to any/all of the available diagnostics.

c

Demand Limiting Binary Input —This function is operational on units with a GBAS and is used to reduce electrical consumption at peak load times.There are two types of demand limiting, 50% and 100%. When demand limiting is needed, mechanical cooling and heating operation are either partially (50%), or completely disabled (100%), in order to save energy.The definition of Demand Limit is user definable at the Human Interface Panel. Demand Limit binary input accepts a field supplied switch or contact closure. When the need for demand limiting has been discontinued, the unit’s cooling/heating functions will again become fully enabled.

6

Evaporator Coil Frost Protection —

FROSTAT™

A temperature sensor on the evaporator is used to determine if the coil is getting close to a freezing condition. Mechanical cooling capacity is shed as necessary to prevent icing.

The FROSTAT™ system eliminates the need for hot gas bypass and adds a suction line surface temperature sensor
