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.
