Carrier 50XJ064-104 Configure Schedules , Program Set Points

8. Enter the last two digits of the current year. Press

thenpress .The LID display will show:

UpdateClock

9. Press 1 and then to cause the controller to

update the clock. The LID display will flash. Press

twice to view the default display and the clock

shouldupdate to the input time and date.

Configure Schedules — Schedules are one method of

starting and stopping the unit at specified intervals. Toconfig-

urethe schedules, perform t he following procedure:

1. Press1 and then .The LID display will show:

OccupancyAlgorit hm

2. Press .The LID display will show:

TimeSchedule

Entert o select

3. Press .If the LID display shows“MODE 0” then

the user is in Maintenance mode and theLID display is

showing the maintenanceinformation for the occupancy

schedule. Press to enter the configuration

mode. The LID display will show:

ManualOverride Hours

0hours

This is the first configuration for each occupancy

algorithm and is used to put theschedule in or out of

occupancy override for the number of hours entered.

4. Press .The L ID display will show:

Period1: Day of week

00000000

Theeight dig its represent if this period should apply to

certain days of the week or holidays. The digits repre-

sentM,Tu,W,Th,F,Sa,Su,andHol,respectively.

Entera seriesof 0s or 1s with a 1 corresponding to the

days that this period should apply to and a 0 for the

days that this schedule should not apply to. As an

example, entering 11111000would make the schedule

applyto days Monday through Friday and not apply to

Saturday,Sunday, or Holidays.

5. Pressthe button.The LIDdisplay will show:

Period1 occupiedfrom

00:00

6. Inputthe Occupancy Starttimef or this period.

NOTE:12.00 represents 12:00 pm.

7. Pressthe toinput the Occupied To time for period 1.

8. Input the days and times for periods 2 through 8 as

required.

9. Pressclear to leavethe occupancy programming.

Program Set Points— To program the set points,

performthe following procedure:

1. Press2 and then . The LID display will show:

Setpoint Schedule

2. Press .The LID display will show:

Supply Fan Status

SETPT01

3. Press .

4. If “No maintenance” is displayed, press to

view the set point information. The LID display will

show:

OccupiedLo S et point

0.30″H2O

This is the pressure set point below which the fan is

consideredto be off.

5. Press .The LID display w ill show:

OccupiedHi Set point

0.40″H2O

This is the pressure set point above which the fan is

consideredto be on.

The down or up arrow will also display the Unoccu-

pied Low and High Temperature set points. These

valuesshould be kept the same as the occupied values.

6. Setpoint 02 internally coordinates the supplyair set point

resetin several of the algorithms and can not be modified.

Setpoint 03 is used for comparison by the unit to return

air, Space temperature or Average space temperature

through linkage to determine when to start reset of the

supply air when occupied, when to turn on heat and

disablecooling when occupied and when tobringthe unit

onfor unoccupied heating or cooling.

Setpoint04 is used to set the head pressure set point if

the unit is ordered with the head pressure control

option. Only the Occupied Low set point may be

modified the other values will change to the Occupied

low valued shortly after it is modified so that all the

valuesremain the same.

Setpoint05 is used to set the supply air static pressure the

unit should maintain. Only the Occupied Low set point

may be modified the other values will change to the

Occupied low value shortly after it is modified so that all

the values remain the same. The set point in the static

pressurecont rolal gorithm will alsofol low and cannot be

modifiedin the algorithm confi guration screens.

Setpoint 06 is the Supply air temperature set point.

Only the Occupied Low set point may be modified the

other values will change to the Occupied low value

shortly after it is modified so that all the values remain

the same. The set point in DX VAV staging and some

of the other algorithms will also follow and cannot be

modified in the algorithm configuration screens.

Setpoint 07 is the building pressure set point for the

building pressure control of a variable speed exhaust

fan from a field-supplied module. Only the Occupie d

Low set point may be modified the other values will

change to the Occupied low value shortly after it is

modifiedso that all thevalues remain the same.

Setpoint 08 is the raw milliamp set point for the build-

ing pressure control and is tied to Setpoint 07 for the

sensor range selected in the custom programming

configuration. Several choices of building static

pressure sensors may be purchased and supplied for

building pressure control.

Setpoint09 is used for the humidification/dehumidification

outputfrom a fi eld-supplied module. This set point may be

modifiedto enable the Humidity output to either humidify

or dehumidify when the indoor relative humidity (IRH)

exceeds the set point.

Table7 lists the available controller set poin ts and their

defaultvalues.

7. Pressing the button will take the user out of the

setpoint configuration mode.
