Compressor 2 Service Alarm Timer
A Compressor 2 Runtime alarm is generated when the compressor
2 run hours exceed this value. Set to 0 to disable.
Range = 0 to 9999 hr
Default = 0 hr
Filter Service Alarm Timer
The amount of time the fan will run before generating a Filter
Alarm. Set to 0 to disable the alarm and reset accumulated fan
hours.
Range = 0 to 9999 hr
Default = 600 hr
Heat 1 Service Alarm Timer
A Heat 1 Runtime alarm is generated when the Heat Stage 1 run
hours exceed this value. Set to 0 to disable.
Range = 0 to 9999 hr
Default = 0 hr
Heat 2 Service Alarm Timer
A Heat 2 Runtime alarm is generated when the Heat Stage 2 run
hours exceed this value. Set to 0 to disable.
Range = 0 to 9999 hr
Default = 0 hr
Door Alarm Delay
Determines the amount of delay before a door alarm is generated.
Range = 0 to 3600 seconds
Default = 60 seconds
Cooling Lockout Temperature
Cooling is inhibited below this outdoor air temperature.
Range = –65 to 80°F
Default = 45°F
Economizer High OAT Lockout Temp
The outdoor air temperature above which economizer cooling is
inhibited.
Range = 55 to 80°F
Default = 75°F
Heating Lockout Temperature
Heating is inhibited above this outdoor air temperature.
Range = 35 to 150°F
Default = 65°F
Unocc Free Cool
Enables or disables the use of the economizer to provide unoccu-
pied free cooling (NTFC).
Range = Disable/Enable
Default = Disable
Minimum Setpoint Separation
The minimum amount of temperature separation between the
heating and cooling setpoints.

INPUTS
Input 2 Function
This input is an analog (4-20mA) input and can be configured to
be one of four different inputs: No Sensor, IAQ Sensor, OAQ Sen-
sor, or Space RH Se sor. Input 2 is wired to pin J4-1,2,3.
Software Default = No Sensor
Factory Default = IAQ Sensor with factory installed CO
sensor
NOTE: For Input 2, if using Carrier air quality sensors do not use
24Vdc from VAV-RTU Open board. External 24Vdc power sup-
ply required.
Δ

2
Input 3
This input is a discrete input and can be configured to be one of
four different functions: No Function, Compressor Safety, Fan
Status, and Filter Status. This input can also be configured to be
either a Normally Open (N/O) or a Normally Closed (N/C) switch.
Input 3 is factory wired to pin J1-2. Field accessories can be wired
to its parallel pin J5-5. You must also set Input 3 Switch
Configuration.
Software Default = No Function
Input 5
This input is a discrete input and can be configured to be one of
four different functions: No Function, Fire Shutdown, Fan Status,
and Filter Status. 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. You must also set Input 3 Switch Configuration.
Software Default = Fire Shutdown and N/C
Factory Default = Fire Shutdown and N/O
Input 5 Switch Configuration
The normal (de-energized) state for the set of contacts terminated
at Input 5.
Range = NO/NC (normally open/normally closed)
Default = NO
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, and
Filter Status. 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 8 Switch Configuration
The normal (de-energized) state for the set of contacts terminated
at Input 8.
Range = NO/NC (normally open/normally closed)
Default = NO
Input 9
This input is a discrete input and can be configured to be one of
seven different functions: No Function, Fan Status, and Filter Sta-
tus, or IGC Override. This input can also be configured to be ei-
ther a Normally Open (N/O) or a Normally Closed (N/C) switch.
Input 9 is factory and field wired to pin J5-7.
Factory Default = N/O
NOTE: For 48LC*B 07-26 Units (gas heat units) this decision is
automatically set to IGC Override and is factory wired.
Input 9 Switch Configuration
The normal (de-energized) state for the set of contacts terminated
at Input 9.
Range = NO/NC (normally open/normally closed)
Default = NO
ZS Sensor Type
The type of local space temperature sensor.
Range =ZS Base, ZS Plus, ZS Pro
Default =None
Rnet Port
Input for communicating sensor or Equipment Touch Terminal
J13 - 1, 2, 3, 4
Range = SPT Sensor, ZS Sensor, or Equipment Touch
Default = None
