DCV Max Vent Damper Pos – This is the greatest

position the economizer can open to while trying to

control the indoor air quality levels

Range = 0 -- 75% open Default = 50% open

Supply Fan Service Alarm Timer – The timer set for the

Supply Fan Runtime Alarm. After the number of hours set

on this point is exceeded the corresponding alarm will be

generated, and must be manually cleared in the maintenance

menu after the maintenance has been completed. The timer

will then begin counting its runtime again for the next due

maintenance.

Range = 0 to 9999 hr Default = 600 hr

NOTE: If set to 0 hr this setpoint is disabled and its alarm

will never be generated.

Comp 1 Service Alarm Timer – The timer set for the

Compressor 1 Runtime Alarm. After the number of hours

set on this point is exceeded the corresponding alarm will

be generated, and must be manually cleared in the

maintenance menu after the maintenance has been

completed. The timer will then begin counting its runtime

again for the next due maintenance.

Range = 0 to 9999 hr Default = 0 hr

NOTE: Default = 0 hours, if set = 0 hr this point is

disabled and its alarm will never be generated.

Comp 2 Service Alarm Timer – The timer set for the

Compressor 2 Runtime Alarm. After the number of hours

set on this point is exceeded the corresponding alarm will

be generated, and must be manually cleared in the

maintenance menu after the maintenance has been

completed. The timer will then begin counting its runtime

again for the next due maintenance.

Range = 0 to 9999 hr Default = 0 hr

NOTE: Default = 0 hours, if set = 0 hr this point is

disabled and its alarm will never be generated.

Filter Service Alarm Timer – The timer set for the Dirty

Filter Alarm. After the number of hours set on this point is

exceeded the corresponding alarm will be generated, and

must be manually cleared in the maintenance menu after the

maintenance has been completed. The timer will then begin

counting its runtime again for the next due maintenance.

Range = 0 to 9999 hr Default = 600 hr

NOTE: Default = 600 hours, if set = 0 hr this point is

disabled and its alarm will never be generated.

Pushbutton Override – Set to enable or disable the push-

button override function of the locally installed space sensor.

Range = Disable/Enable Default = Enable

Door Alarm Delay -- Determines the amount of delay

before a door alarm is generated.

Range = 0 to 3600 seconds Default = 60 seconds

Setpoint Adjustment – Set to enable or disable the setpoint

adjustment function of the locally installed space sensor.

Range = Disable/Enable Default = Enable

Setpoint Adjustment Range -- Sets the slider range of a

space sensor (with built in function). The slider is used to

offset the control setpoint

Range = 0 to 5_F Default = 5_F

Cooling Lockout Temperature -- This defines the

minimum outdoor air temperature that cooling mode can

be enabled and run. If the OAT falls below this number

during cooling the compressors will be de-energized

Range = --65 - 80_F Default = 45_F

Economizer High OAT Lockout Temp – If the outdoor

air temperature rises above this value, economizer cooling

will be disabled and dampers will return and stay at

minimum position.

Range = 55 - 80_F Default = 75_F

Heating Lockout Temperature – This defines the

maximum outdoor air temperature that heating mode can

be enabled and run. If the OAT rises above this number

during heating the heat stages will be de-energized.

Range = 35 -- 150_F Default = 65_

Pre--Occupancy Purge -- Enables or disables the use of a

purge cycle immediately prior to the start of a scheduled

occupied period.

Range = Enable/Disable Default = Disable

Purge Time -- The maximum amount of time used for a

pre--occupancy purge.

Range = 0 to 240 minutes Default = 60 minutes

Unocc Free Cool Enable – Set to enable or disable the

economizer for night time free cooling (NTFC) operation.

Range = Disable/Enable Default = Disable

Setpoint Separation – Sets the minimum separation gap

in which setpoints can be set.

Range = 2 - 10_F Default = 5_F

Occupancy Source – Tells the controller which method of

occupancy control to use in determining occupancy of the

rooftop. Refer to Occupancy in the operation section for

detail on each specific operation function.

Range = Always Occupied, BACnet Schedule,

BAS On/Off, or Remote Occ Input

Default =Always Occupied

Inputs

Input 1 Function – This input is an analog input and can

be configured to be one of four different inputs: No

Sensor, IAQ Sensor, OAQ Sensor, or Space RH Sensor.

Input 1 is wired to pin J4--4,5,6.

Default = No Sensor

Input 2 Function – This input is an analog input and can

be configured to be one of four different inputs: No

Sensor, IAQ Sensor, OAQ Sensor, or Space RH Sensor.

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 Inputs 1 & 2, if using Bryant air quality

sensors do not use 24Vdc from RTU Open board. External

24Vdc power supply required.

Input 3 -- This input is a discrete input and can be

configured to be one of six different functions: No

Function, Compressor Safety, 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 3 is factory wired to

pin J1-2. Field accessories can be wired to its parallel pin

J5-5.

Factory Default = Compressor Safety and N/O
