Understanding 5-2 Day Programming
It is recommended that you read and understand these instructions
before you attempt to program your new thermostat.
Events and Temperatures (Setpoints)
Programming a 5-2 day thermostat is easy once you understand how it
works. The 5 refers to the 5 weekday period, Monday through Friday. The 2
refers to the 2 weekend days, Saturday and Sunday. The weekday period is
divided into 4 events. An event is a designated period of time during the
day. The events are called Morning, Day, Evening and Night. Thus, the
weekdays are divided into Morning, Day, Evening and Night or 4 events.
The same holds true for the weekend days. Each of the 4 events is pro-
grammed for a cooling temperature. To exit programming at any time press
and release the RESUME button, or 15 seconds after pressing the last but-
ton the display will automatically change to the normal display.

Skipping an Event (2 Methods)
Your personal schedule may not require the use of all 4 events on a partic-
ular day. For example, if you wish to go from the Day event directly to the
Night event and skip over the Evening event, there are 2 methods you can
apply:
A. - Press and release the PROGRAM button until you come to the week-
day or weekend event hour that you wish to skip.
- Press and hold down the PROGRAM button and at the same time
press and release the MODE button. In the time display area you will
see _ _ : _ _ indicating that the event is skipped.
B. If any two or more events have the same start time, the latest event
in the day has priority and therefore uses its setpoints.
Reviewing Scheduled Times and Setpoints
You may wish to review the program schedule. You may do this by repeat-
edly pressing and releasing the PROGRAM button. Each of the scheduled
events will be displayed starting with the weekday start times and tempera-
tures. To cancel your review, simply press and release the RESUME button,
or wait 15 seconds for the thermostat to resume the display automatically.
Viewing the Outdoor Temperature (Option)
If your thermostat has been installed with an electronic outdoor remote
sensor, you may view the outdoor temperature simply by pressing the
OUTDOOR button. Upon releasing the button, the thermostat will once
again display the indoor temperature.

For example, you may begin by programming the weekday Morning event
setpoint to cool to 70˚F. As a result, every weekday Morning event will cool
to 70˚F. Next select the Day event and cooling setpoint. Continue until you
have programmed all 4 events in the same fashion. The setpoints that you
have selected to represent your events will be consistent for the 5 week-
days, Monday through Friday. You will go through the same procedure to
set the weekend (Saturday and Sunday) events. If you change a setpoint
in any of the weekday or weekend events, it will change the corre-
sponding setpoint for that particular event in either the weekday or
weekend programs, whichever period the event occurs in.
Event Times
You are required only to set a starting time for each event. An event ends
at the same time that the next event begins. For example, you may choose
to have the Morning event begin at 6:00 AM and the Day event set to begin
at 9:00 AM. The Morning event and the temperature will automatically
change to the Day event setpoint at 9:00 AM.
You must program the 4 events and their corresponding setpoints into your
thermostat for both the weekday and weekend periods.
Temporary Temperature Override
6
You may wish on occasion to temporarily change the scheduled setpoint
during an event. You may do this at any time without affecting the pro-
gram. Simply press the ✞ or ✟ buttons to lower or raise the setpoints. The
new setpoint will be retained for 3 hours and will not affect the program-
ming schedule. You may return to the regular program schedule by press-
ing the RESUME button.
Temporary Temperature Override with Keypad Locked
(The keypad may be locked to prevent tampering by selecting the ON posi-
tion of DIP switch #2.)
If the keypad is locked to prevent tampering you may still temporarily
adjust the setpoint by ±3°C or ±6°F of the programmed Morning (4 event) or
Day (2 event) setpoint without affecting the program. Press the ✞ or ✟ but-
ton to raise or lower the setpoint for a 1 hour period. This override may not
be cancelled by pressing the RESUME button.
Constant Override
To maintain a temperature setting for an indefinite period of time, press
and release the HOLD button. The word HOLD will appear on the LCD. The
current scheduled setpoint will be maintained. To select a different set-
point, press the ✞ or ✟ button to raise or lower it. The last setpoint select-
ed (scheduled or new) will be maintained continuously until the RESUME
button is pressed.
Off Mode
To turn off the cooling system, press the MODE button until the word OFF
appears on the LCD. It will remain displayed until the mode is changed.
The OFF mode prevents the system from being energized.
