Input 5 -- This input is a discrete input and can be

configured to be one of six different functions: No Function,

Fire Shutdown, Fan Status, Filter Status, Remote Occupancy,

or Door Contact. This input can also be configured to be

either a Normally Open (N/O) or a Normally Closed (N/C)

switch. Input 5 is factory wired to pin J1-10. Field

accessories can be wired to its parallel pin J5-3.

Software Default = Fire Shutdown and N/C

Factory Default = Fire Shutdown and N/O

Input 8 -- This input is a discrete input and can be

configured to be one of six different functions: No

Function, Enthalpy Switch, Fan Status, Filter Status,

Remote Occupancy, or Door Contact. This input can also

be configured to be either a Normally Open (N/O) or a

Normally Closed (N/C) switch. Input 8 is factory wired to

pin J2-6. Field accessories can be wired to its parallel pin

J5-1.

Software Default= Enthalpy Switch and N/O

Factory Default = No Function and N/O without

factory installed enthalpy sensor

Input 9 -- This input is a discrete input and can be

configured to be one of seven different functions: No

Function, Humidistat, Fan Status, Filter Status, Remote

Occupancy, or Door Contact. This input can also be

configured to be either a Normally Open (N/O) or a

Normally Closed (N/C) switch. Input 9 is factory and field

wiredtopinJ5-7.

Factory Default = Humidistat and N/O

Space Sensor Type – This tells the controller what type

of space sensor is installed to run the unit. The four types

that can be used are: a standard 10k Type II thermistor

(T55), sensor with a setpoint offset slider bar (T56), or a

communicating sensor (SPT Sensor) and, ZS Sensor.

Range =T55, T56 (Use for T59), SPT Sensor,

or ZS Sensor

Default = T55

ZS Sensor Type -- The type of local space temperature

sensor.

Range =ZS Base, ZS Plus, ZS Pro

Default = None

T5x Override Duration – Sets the override time duration

the unit will change from unoccupied to occupied when

the override button is pushed on the space sensor.

Range = 0-24 hours Default = 1 hour

Rnet Port -- input for communicating sensor

Range = SPT Sensor or ZS Sensor

Default= None

Service Configuration

Unit Type – This tells the control what type of unit it is

controlling. Heat/Cool refers to gas and electric heat units.

HP O/B Ctrl refers to a heat pump unit which requires

reversing valve control. HP Y1/W1 Ctrl refers to a heat

pump unit whose reversing valve is built in to the cooling

or heating call. This decision is factory configured for the

specific unit type as supplied.

Compressor Stages – This refers to the number of

mechanical cooling stages available on a specific unit.

Factory Default = “One Stage” for 1 compressor

units or “Two Stages” for 2

compressor units.

Economizer Exists – This indicates if there is an

economizer installed on the unit.

Factory Default =NO if no economizer, or YES if

there is an economizer installed

Fan Control -- This refers to the type of fan control for

the unit.

Range = Single Speed, Two Speed,

or Variable Speed

Factory Default = Single Speed --

(04--07 and A08--A12)

Two Speed--

(units with VFD option)

VFD Input -- Defines the electrical control signal used by

the VFD’s input.

Range = 2--10VDC or 0--10VDC

Factory Default = 2--10 VDC

Max VFD Output --ThemaximumVFDsignalRTUOpen

supplies to the VFD as a percentage of its range. The

balancer can set this to adjust the unit’s maximum airflow.

Applies to Variable Speed fan control.

Range = 33--100% Default = 100%

Min VFD Output -- The minimum VFD signal RTU Open

supplies to the VFD as a percentage of its range. The

balancer can set this to adjust the unit’s minimum airflow.

Applies to Variable Speed fan control only.

Range = 33--100% Default = 40%

Dehum Min VFD Output -- The minimum output signal

supplied by RTU Open during dehumidification as a

percentage of its range. Applies to Variable Speed fan

control only .

Range = 50--100% Default = 100%

Stage 1 SAT Setpoint -- The VFD Supply Air Setpoint

during stage 1 cooling. Must be at least 4_F greater than

Minimum Cooling SAT parameter

Range = 45 -- 75_F Default = 57_F

Stage 2 SAT Setpoint -- The VFD Supply Air Setpoint

during stage 2 cooling. Must be at least 4_F greater than

Minimum Cooling SAT parameter

Range = 45 -- 75_F Default = 57_F

Stage 3 SAT Setpoint -- The VFD Supply Air Setpoint

during stage 3 cooling. Must be at least 4_F greater than

Minimum Cooling SAT parameter

Range = 45 -- 75_F Default = 56_F

Heat Type – Indicates the type of heat which is installed in

the unit. Electric is any unit without gas and a Gas unit is

one which requires gas input for heating.

Factory Default = Gas for gas units and Electric for

all other units (cooling only units and heat pumps)
