Once you have gone through the programming procedure for
Monday, ending at the Night
✠
event, the word COPY will appear.
You may choose to copy the 4 event start times to other days of
the week. Press the
✞
button to display all the days of the week.
Press the
✟
button to select the consecutive days of the week
that you want the events to apply to. Press the PROGRAM button
to do the copy or press the RESUME button to return to the nor-
mal display.
Individual Days
If certain days of the week require different event starting times,
follow the procedure below.
1. Press and release the PROGRAM button.
2. Press the
✞
or
✟
button to advance the day indicator to the
desired day.
3. Press and release the PROGRAM button to change the event
hours and minutes to the desired starting times as in “Setting
the Event Start Times.”
4. Press the RESUME button to return to the normal display.
Skipping an Event (2 Methods)
Your personal schedule may not require the use of all 4 events on
a weekday. 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 use:
A. Press and release the PROGRAM button until you come to the
day and event hour on the day that you wish to skip.
A)
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
To review the program schedule, repeatedly press and release the
PROGRAM button. Each of the scheduled events is displayed
starting with the temperature, day, hour and minute for each day
of the week. To cancel your review, press the RESUME button, or
simply wait 2 minutes for the thermostat to resume the display
automatically.
Reviewing Programmed Temperatures
To review your programmed temperatures, repeatedly press the
SET TEMP button. The display will change to show the mode,
event, and the setpoint selected.
Viewing the Outdoor Temperature (Option)
If your thermostat has been installed with an electronic outdoor
remote sensor ( SLIDS), 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.
Temporary Temperature Override
To temporarily change the scheduled setpoint during an event
without affecting the program, press the
✞
or
✟
buttons to lower
or raise the setpoints. The new setpoint will be retained for 3
hours and will not affect the programming schedule. You may
return to the regular program schedule by pressing the RESUME
button.
Temporary Temperature Override with Keypad Locked
(The keypad may be locked to prevent tampering by selecting the
ON position of DIP switch #4.)
With the keypad locked to prevent tampering you may temporarily
adjust the setpoint by ±3°C or ±6°F of the programmed Morning
(4 event) or Day (2 event) setpoint without affecting the regular
program. Press the
✞
or
✟
button to raise or lower the setpoint
for a 1 hour period. This override may not be cancelled by press-
ing the RESUME button.
Constant Override
To maintain a temperature setting for an indefinite period of time,
press the HOLD button. The word HOLD will appear on the LCD.
The current scheduled setpoint will be maintained. To select a dif-
ferent setpoint, press the
✞
or
✟
button to raise or lower it. The
last setpoint selected (scheduled or new) will be maintained con-
tinuously until the RESUME button is pressed.
Off Mode
To turn off the heating or 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. Avoid using the OFF mode during extreme-
ly cold weather to prevent damage to the equipment from freez-
ing.
Auto Changeover Mode
To set the thermostat to automatically switch from heating to
cooling, press the MODE button until the word AUTO and both
the heating
,
and cooling
☛
icons appear on the LCD. The ther-
mostat energizes the heating or cooling system based on the
temperatures established for both modes.
SET YOUR PERSONAL SCHEDULE
This blank chart is for your use. Start by selecting your heating and cooling temperature
setpoints. Determine the time you want the temperatures to be active. Write the desired
times in the appropriate box. Typically, programming would begin on Monday, allowing
you to copy the Monday schedule to the consecutive days of the week.
To skip a particular event for a particular day,
select the day and event, hold the PROGRAM
button in at the hour or minute section, then press
the MODE button. This will put four dashes in the
hour and minute section.
INSTALLATION INSTRUCTIONS
Location
Mount the thermostat on an inside wall in a frequently occupied
area of the building. Its position must be at least 18" (46cm) from
any outside wall, and approximately 5' (1.5m) above the floor in a
location with freely circulating air of average temperature. Avoid
the following locations:
- behind doors or in corners where circulating air is unavailable
- where radiant heat from appliances might affect control operation
- on an outside wall or door, in direct sunlight or in stairwells
- adjacent to, or in line with, conditioned air discharge grilles
- where operation may be affected by steam or water pipes or
warm air stacks in an adjacent partition space, or by an unheat-
ed/uncooled area behind the thermostat
- where its operation is affected by supply air of an adjacent unit
- near electrical interference (e.g., arcing relay contacts)
Removing the Thermostat from the Subbase
1. Insert a flat blade screwdriver or coin
1
⁄
8
" (3mm) into the slot located in
the bottom center of the thermostat case and twist
1
⁄

turn.
When you feel or hear a click, grasp the case from the bottom
two corners and separate from the subbase. Some models
require more force than others when separating.
2. Swing the thermostat out from the bottom.
3. Lift the thermostat up and off the subbase.
4. Place the rectangular opening in the subbase over the equip-
ment control wires protruding from the wall and, using the sub-
base as a template, mark the location of the two mounting holes.
(Exact vertical mounting is necessary only for appearance.)
5. Use supplied anchors and screws for mounting on drywall or

COULD RESULT IN A HAZARDOUS CONDITION
plaster; drill two

⁄
16
" (5mm) diameter holes at marked locations;
use a hammer to tap nylon anchors in flush to the wall surface
and fasten subbase using supplied screws. (Do not overtighten!)
6. Connect the system wires to the thermostat terminals as shown
in the wiring diagrams. Carefully dress the wires so that any
excess is pushed back into the wall cavity or junction box.
Ensure that wires are flush to the plastic subbase. The access
hole should be sealed or stuffed to prevent drafts from affecting
the thermostat.
7. Before the thermostat is reinstalled on the subbase, install the
optional clock/timer, indoor remote sensor and outdoor remote
sensor, if used. Refer to installation instructions supplied with
each. Also check DIP switch positions on the back of thermostat.
Replacing the Thermostat on Subbase
1. Position the thermostat on the hinged
tabs at the top of the subbase.
2. Gently swing the thermostat down and
press on the bottom center until it
snaps into place.
Thermostat Cover Lock
Insert the plastic lock piece into the bot-
tom of the mounted base. The ends of the
lock piece fit snugly under the lock pins
extending from the bottom of the mounted
base. The tab in the middle of the lock
piece extends down from the base.
To release the locking mechanism, press
the lock piece up and into the base while
gently prying open.
Thermistor location Instructions
When placing the front cover on the ther-
mostat, ensure the thermistor is not bent
or misaligned. Ensure that the thermistor
does not touch the thermostat case. The
thermistor should be placed horizontal to the wall.
Thermistor location Instructions (cont’d)
Ensure the thermistor is not pushed upward into the case. The
thermistor should be aligned so it is visible between the ribs on
the bottom of the subbase.
WIRING DIAGRAM
This thermostat may
be used with 24V DC.
The negative side of
the DC supply must
be wired to the 24V(c)
terminal. Note: If the
24V(c) is not available
from the equipment,
the jumper may be
removed and a sepa-
rate 24V transformer
must then be used to
power the thermostat.
To remove jumper
(labeled JP1) from the
printed circuit board,
pull straight out.
