S7760A COMMAND DISPLAY

FOR RAPIDZONE SOLUTION

GENERAL

The command display shows system variables and alarms.

You can also modify setpoints, schedules, basic system

parameters and acknowledge alarms at the display. Easy

navigation between building, zone and diagnostic views allow

you to quickly tailor the RapidZone system for comfort and

energy savings.

The system must first be configured using the RapidZone

Software package. The RapidZone software is designed pri-

marily for your HVAC contractor to configure and monitor your

rooftop unit (RTU) and zone controllers. For more information

refer to the RapidZone Application Guide 74-3449 and the

S7760A Command Display User Guide 74-2974.

The command display is an easy way to make changes to the

schedules and other configuration options after the Rapid-

Zone application is downloaded.

Room temperature, setpoints, occupancy schedules, equip-

ment alarms, current date and password access are some

data screens that you are able to work with when using the

RapidZone command display.

ZONES

Control data and settings for individual zones can be viewed

and modified using the RapidZone command display. A

typical screen is displayed below.

TO CHANGE TEMPERATURE SETPOINTS

Starting at the Main screen, make the following selections to

select the specific zone whose setpoint you want to change.

Main—>BuildngVw—>Zone Data—>Zone Name

• Press ChngValue to view and modify setpoints.

— Highlight Details and press the down arrow key to

display the setpoint screen below. Use + or - and

press Apply to change the temperature setpoint.

NOTE: Standby setpoints must always be set equal to the

unoccupied temperature setpoint.

• Press the Back key to return to the first Zone Name

screen.

• Press OccOvride to display the override screen where

you can set timed or continuous Occupied or Unoccupied

override.

NOTES:

— The Occupied setpoint defines the comfort level

desired during periods when a given area or zone

is in use. The Unoccupied setpoint captures

operational, equipment and energy savings

during periods when a given area or zone is not

in use.

— In zones with temperature sensor and setpoint

adjustment, the occupied temperature setpoint is

controlled by the zone sensor. The command

display should not be used to modify the

occupied setpoints for these zones.

— Be sure to press the Apply key after you’ve made

any changes that you want saved.

Schedules

The RapidZone solution allows the user to define up to eight

separate schedules that specify different periods throughout

the day where temperatures in the assigned zones will be

maintained at the occupied setpoint for comfort, or the unoc-

cupied setpoint for energy savings. Each of these schedules

can be assigned to any single zone or combination of zones

using the RapidZone software. Each RapidZone schedule

consists of a normal daily schedule (Monday through Sunday)

that allows the operating hours for each day to be separately

defined. Each RapidZone schedule also provides for up to

two temporary periods that can be programmed for unusual

days where occupancy periods do not follow normal daily or

special holiday hours, e.g. inventory or vacation times.

Finally, each RapidZone schedule allows for the programming

of up to three special days whose occupancy periods can be

assigned to the various scheduled holidays throughout the

year. Each of these components - daily, temporary and spe-

cial, are unique to the schedule being programmed and apply

only to the zone(s) assigned to that schedule. Holidays are

defined for, and available to, all schedules. Holidays may be

assigned to include or exclude individual schedules as

appropriate.

The following is an illustration of the various components that

make up a RapidZone schedule.

For more detailed information regarding schedules, refer to

the XL15 Command Display Users Guide 74-2974.

To view or modify a schedule, from the Main screen select

BuildngVw then Zone Data. Highlight the zone whose sched-

ule you want to view/modify and press the Schedule softkey.

Enter the required password and press Apply. (Refer to the

password section.)

There are four types of schedules:

• Days—for daily operating hours under normal conditions.

• Temp—for temporary operating hours not associated with

holidays.

• Special—for special hours that can be assigned to

holidays.

• Holiday—for holidays.

NOTE: When changing schedules, always press Apply to

save the updates.

DAYS

Pressing the Days softkey allows you to modify separate

daily schedules Monday through Sunday. A typical schedule

is shown below with an Occupied period for Monday from

7:00 AM (E1) to 6:00 PM (E2).

• Press the Days softkey:

All schedule changes for the selected zone automatically

apply to all zones assigned to that schedule.

• Press plus (+) or (-) soft keys to change values.

The Occ on line E1 indicates that RapidZone will control to

the occupied setpoint from 7:00 AM until the next scheduled

event (E2). The Unocc on line E2 indicates that RapidZone

will control to the unoccupied setpoint from 6:00 PM on.

UNCNFIG (unconfigured) indicates that no change occurs

from the previously programmed event (e.g. E2).

NOTE: The STNDBY is not used in the RapidZone applica-

tion and should not be programmed.

TEMP

The Temp softkey allows the user to program up to 2 sets of

temporary hours for one or more days that override the daily

(and holiday) schedules.

• Press the Temp softkey:

Diagnostics

The Rooftop Unit Diagnostics screen provides a quick status

of critical system parameters.

Main—>BuildngVw—>Rooftop Unit Diagnostics

NOTES:

— FanFailure appears only when monitoring a

system with a proof of air flow sensor.

— EconoFailure appears only when the system has

an economizer.

— Alarms feature will not be active unless the

system has an Excel 15A building manager.

Alarms

Use this screen to check for alarms and get information if an

alarm has occurred. Use Next and Prev to navigate through

the alarms. Use Ack to acknowledge alarms. Once an alarm

has been acknowledged it is no longer viewable via the

command display. Use Silence if the beep function is

activated.

To View Alarms

Press the Alarm softkey and enter the required password.

Main—>Alarms

Alarms are another diagnostic tool provided by RapidZone.

Critical system parameters are constantly monitored within

the RapidZone application. Any deviation outside of preset

limits will trigger an alarm. The RapidZone Command Display

indicates an active alarm by sounding an intermittent beep

and/or by flashing the !! indicator. Active alarms can be dis-

played by pressing the Alarms softkey.

NOTE: Once the conditions that triggered the alarm have

been cleared, a second alarm is issued with the orig-

inal text preceded by RTN (return to normal).
