Inputs
NOTE: For installation of inputs and field installed
accessories, refer to the appropriate sections.
Input 3
This input is a discrete input and can be configured to be
one of five different inputs: No Function, Compressor
Safety, Fan Status, Filter Status, or Remote Occupancy.
This input can also be configured to be either Normally
Open (N/O) or Normally Closed (N/C). Input 3 is factory
wired to pin J1--2. Field accessories get wired to its
parallel pin J5--5. Do not connect inputs to both locations,
one function per input.
Factory Default = Compressor Safety and N/O
NOTE: Compressor Safety input comes from the CLO
board. J1--2 is always factory wired to TB1--8 (X) terminal
on the unit. If the unit has a CLO board, do not configure
input 3 for anything but Compressor Safety.
Input 5
This input is a discrete input and can be configured to be
one of five different inputs: No Function, Fire Shutdown,
Fan Status, Filter Status, or Remote Occupancy. This
input can also be configured to be either Normally Open
(N/O) or Normally Closed (N/C). Input 5 is factory wired
to pin J1--10. Field accessories get wired to its parallel pin
J5--3. Do not connect inputs to both locations, one
function per input.
Factory Default = Fire Shutdown and N/C
NOTE: Fire Shutdown input comes from TB4--7. J1--10
is always factory wired to TB4--7. Only change input 5s
function if absolutely needed.
Input 8
This input is a discrete input and can be configured to be
one of five different inputs: No Function, Enthalpy
Switch, Fan Status, Filter Status, or Remote Occupancy.
This input can also be configured to be either Normally
Open (N/O) or Normally Closed (N/C). Input 8 is factory
wired to pin J2--6. Field accessories get wired to its
parallel pin J5--1. Do not connect inputs to both locations,
one function per input.
Factory Default = No Function and N/O
Input 9
This input is a discrete input and can be configured to be
one of five different inputs: No Function, Humidistat, Fan
Status, Filter Status, or Remote Occupancy. This input can
also be configured to be either Normally Open (N/O) or
Normally Closed (N/C). Input 9 is factory and field wired
to pin J5--7. Do not connect inputs to both locations, one
function per input.
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 three types that can be used
are the T55 space sensor, the T56 space sensor, or the RS
space sensor.
Factory Default = T55 Type
Input 1 Function
This input is an analog input and can be configured to be
one of five different inputs: No Sensor, IAQ Sensor, OAQ
Sensor, Space RH Sensor, or Outdoor RH Sensor. Input 1
iswiredtopinJ4--5.
Factory Default = No Sensor
Input 2 Function
This input is an analog input and can be configured to be
one of five different inputs: No Sensor, IAQ Sensor, OAQ
Sensor, Space RH Sensor, or Outdoor RH Sensor. Input 2
iswiredtopinJ4--2.
Factory Default = No Sensor
Setpoint Slider Range
This sets the slider range of the space sensor (with this
built in function). The slider is used to offset the current
control setpoint.
Factory Default = 5 n_F
Range = 0--15 n_F
T55/56 Override Duration
This sets the occupancy override duration when the
override button is pushed on the space sensor.
Factory Default = 1 hr
Range = 0--24 hr
IAQ Low Reference @ 4mA
This is used when an IAQ sensor is installed on Input 1 or
2. This value is displayed and used when 4mA is seen at
the input.
Factory Default = 0 PPM
Range = 0--400 PPM
IAQ High Reference @ 20mA
This is used when an IAQ sensor is installed on Input 1 or
2. This value is displayed and used when 20mA is seen at
the input.
Factory Default = 2000 PPM
Range = 0--5000 PPM
NOTE: IAQ low Reference @ 4mA and IAQ High
Reference @ 20mA are used to set the linear curve of mA
vs. PPM.
OAQ Low Reference @ 4mA
This is used when an OAQ sensor is installed on Input 1
or 2. This value is displayed and used when 4mA is seen
at the input.
Factory Default = 0 PPM
Range = 0--400 PPM
OAQ High Reference @ 20mA
This is used when an OAQ sensor is installed on Input 1
or 2. This value is displayed and used when 20mA is seen
at the input.
Factory Default = 2000 PPM
Range = 0--5000 PPM
NOTE: OAQ low Reference @ 4mA and OAQ High
Reference @ 20mA are used to set the linear curve of mA
vs. PPM.
