STEP 7: CONFIGURING UNITS

Prism 2 Technical Guide

Configuring Units

Select <Setpoints> to view each setpoint screen associated with

the control type. You must have a Level 3 passcode to access most

of the setpoints on these screens.

Select

<Trendlogs> to open the normal trend log screen and

perform whatever task you normally would from that screen.

Select <Print> to send the printout to a preview window where you

can then select the printer. The printout will be in text format with

a list of the important status information.

Select <Cancel Force Modes> to immediately cancel all force

modes. Force Modes will automatically cancel on their own 10

minutes after Prism 2 goes Off Line.

Controller Override, Schedule, and Holiday

Conﬁ guration

At the top of the status screen next to the Occupied/Unoccupied

indicator are the buttons < Override>, < Schedule>, < Holidays>,

and <ALARM>.

The <Override> button overrides the current occupied/unoccupied

operating mode. The <Schedule> button accesses the weekly

schedule and the <Holiday> button accesses the holiday schedule.

The <ALARM> button accesses the Unit Alarm Status &

Conﬁ guration Screen, discussed on page 27.

Controller Overrides

If the controller supports it, you can override the

schedule mode of operations by clicking on the

<Override> button. The Overrides Window will

appear.

You can choose

Force Schedule

ON or Force Schedule OFF or

you can choose Fan Only Mode

to force the Main Fan to operate

without any cooling or heating

being activated due to space

temperature demands.

A scheduled force override will

remain in effect until cancelled.

To cancel an override, select the

Auto Scheduling option.

NOTE: Not all units support the Fan Only Mode. In

these cases, it will not be displayed as an option.

Controller Weekly Time Schedules

When you select the <Schedule> button, the

Schedules Window will appear.

The Schedules Window in the example shows an 8:00 AM to 5:00

PM operating schedule for Monday through Friday. The bars on

the right side of the screen give a visual indication of the selected

time periods.

NOTE: Some controllers do not have two start/stop events per

day. The Schedules Window will reﬂ ect this by having the Event

#2 columns grayed out.

When you enter a time in any ﬁ eld, you must designate AM or PM

and press <ENTER>.

NOTE: You MUST press <ENTER> to have the system accept

your entry. If you do not press <ENTER>, the bar graph to the

right will either not display or will not change.

The holiday start and stop times will override the standard

operating hours. The holidays themselves are scheduled in the

Holiday Schedule Window described on page 24.

To eliminate a schedule from any event, simply type a zero and

press <ENTER> for the Start and Stop time for that day. The screen

will display 12:00 AM for both the Start and Stop times, indicating

that the equipment will not activate for that day.

If you want the controller to run the full 24 hours, type a zero and

press <ENTER> to set 12:00 AM for the Start time and type 11:59

PM and press <ENTER> for the Stop time. This ensures the full 24-

hour period will remain in the occupied mode without interruption.

Select < Save> to save your schedule. Select < Restore> to restore

a previously saved schedule. Select < Copy to All> to copy the

schedule to all like controllers, and select < Erase Schedules> to

completely erase the schedule appearing in the window.
