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 six 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 wired to pin J5-7.
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 three 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).
Range = T55, T56, or SPT Sensor
Default = T55
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
Service
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.
Factory Default = Heat/Cool for non-heat pump
units, or HP Y1/W1 Ctrl for heat pump units.
Compressor Stages – This refers to the number of
mechanical cooling stages available on a specific unit.
Set this point to “One Stage” if there is one compressor in
the specific unit, set to “Two Stage” if there are two
compressors in the unit, and set to “None” if economizer
cooling ONLY is desired.
Factory Default = “One Stage” for 1 compressor
units, or “Two Stages” for 2 compressor units
Economizer Exists – This tells the controller if there is an
economizer installed on the unit.
Factory Default = NO if no economizer, or YES if
there is an economizer installed
Reversing Valve Type – Sets the heat pump’s (HP O/B
Ctrl type) reversing valve function. O output type refers
to a valve that is energized for cooling, and B output type
refers to a valve that is energized for heating.
Default = O output type
Heat Type – Tells the controller which type of heat the
unit is capable of. Electric is any unit without gas and a
Gas unit is one which requires gas input for heating.
Factory Default = Electric for cooling only units
and heat pumps, or Gas for gas units.
Number of Heat Stages – Tells the controller how many
heat stages outputs are available for use. See
configuration in Appendix A for details on specific unit
configuration.
Factory Default = 1 for single heat stage units,
2 for duel stage units, or 0 for cooling only units.
Continuous Occupied Exhaust – This point tells the
controller when to run the power exhaust if equipped on
the unit.
If set to YES, the power exhaust will be on all the time
when in occupied mode and will be off when in
unoccupied mode. If set to NO the power exhaust will be
controlled by the Power Exhaust Setpoint.
Default = NO
Indoor CO
2
Sensor Value @ Min mA – Sets the indoor
CO
2
value when the board reads 4 mA at input 1 or 2.
Default 0 ppm
Indoor CO
2
Sensor Value @ Max mA – Sets the indoor
CO
2
value when the board reads 20 mA at input 1 or 2.
Default 2000 ppm
Outdoor CO
2
Sensor Value @ Min mA – Sets the
outdoor CO
2
value when the board reads 4 mA at input 1
or 2.
Default 0 ppm
Outdoor CO
2
Sensor Value @ Max mA – Sets the
outdoor CO
2
value when the board reads 20 mA at input 1
or 2.
Default 2000 ppm
NOTE: The indoor and outdoor min and max mA setting
are used to set the linear curve of mA vs. PPM.
Clockset
This submenu screen allows you to set the date and time
manually. The Daylight Savings Time (DST) can also be
changed here. The date and time is automatically set
whenever software is downloaded. The clock is a 24 hour
clock and not am/pm. The time should be verified (and
maybe changed) according to unit location and time zone.
Factory Default = Eastern Standard Time
