1) Install the base onto an electrical box.
2) Place the FAN switch as follows:
Place at Yes if you have a fan-forced
heater (to prevent premature burnout
of the motor).
Leave at No for better temperature
regulation if you do not have a
fan-forced heater.
3) Reinstall the faceplate on the base and
secure it in place with the screw.
4) Apply power to the thermostat at the
main electrical panel.
Installing the thermostat
Keep air vents at top and
bottom of thermostat clean and
unobstructed at all times.
FAN switch
If you change the FAN switch position after you
have already applied power to the thermostat,
disconnect power to the thermostat at the
electrical panel for 3 seconds. The thermostat
will use the new setting when you reapply power.

The Away mode can be used when you are away for an undetermined length of time. For frost
protection while saving energy, the Away temperature is set by default at 15°C (59°F) and
cannot be modified by simply pressing the Up or Down button. To modify the Away
temperature, see page 16.
NOTE: The Away mode can also be used to prevent tampering of the setpoint temperature in
the summer season when heating is not required.

Use the Countdown mode if you wish to keep the same temperature for a predetermined length of
time. The choices of countdown times are: 15, 30 or 45 min, or 1, 2, 4, 8, 12 or 18 hr, or 1 to 14 days.
At the end of the countdown, the thermostat automatically returns to the previous mode and uses the

When placed in Automatic mode (see page 8), the thermostat follows the programmed
schedule. By default, the thermostat is programmed with the following schedule:
The schedule consists of 4 periods per day, which represents a typical work day. However, you
can program the thermostat to skip (cancel) the periods that do not apply to your situation. For
example,
Leave and Return periods are skipped for the weekend in the default schedule.
You can choose a different program every day; i.e., each period can have a different starting
time and a different temperature every day.

To modify the schedule, proceed as follows:
To skip a period : When the hour or the temperature of the period is flashing, press the Up and Down
buttons at the same time. (Alternatively, set its hour between 23:00 [11:00 PM] and 0:00 [midnight] or
its temperature below 5°C [41°F].) Its time and temperature display will be replaced by dashes (-).
NOTE: If you do not press any button for one minute, the thermostat will automatically save any
changes you have made and will
return to its normal display .

1Away temperature
Set the temperature you wish to use when the thermostat is in Away mode (see page 10).
2Daylight Saving Time
When the Daylight Saving Time function is enabled (On), the thermostat automatically switches to Daylight
Saving Time on the second Sunday of March and to normal time on the first Sunday of November.
3Early Start
Early Start is used in Automatic mode only. When Early Start is enabled (On), the thermostat determines
when to start heating so the desired temperature is attained at the beginning of Wake and Return periods.
When Early Start is disabled (Off), heating starts only at the beginning of Wake and Return periods; thus
there is a delay before you reach the desired temperature.
4Minimum and maximum setpoints
These parameters are used to modify the setpoint range and are applicable in all operating modes.
5Keypad Lock
When keypad lock is enabled (On), no other setting change is permitted on the thermostat. The message
Lock appears when you try to change any other setting.

In case of difficulty
PROBLEMS SOLUTIONS
Thermostat is hot.
This is normal. Ensure that the heater capacity does not exceed the thermostat’s maximum
load. Keep thermostat air vents clean and unobstructed at all times.
Displayed temperature is incor-
rect.
Remediate if any the following conditions exists:
• The thermostat is exposed to air draft.
• The thermostat is located near or above a heat source such as a light dimmer.
• The thermostat displays LP
instead of the temperature.
• The screen is blank.
The thermostat is currently without power. This can happen in either condition:
• There is a power outage.
• The thermal protection device on the heater is opened. This can happen if the heater is
obstructed by furniture or curtain and has overheated, or if the heater’s thermal protection
device is too sensitive.
LP appears for the first five minutes. Then the screen becomes blank.
TIME is flashing. The thermostat was without power for more than 4 hours. Set its clock and date (Time menu).
Temperature does not change
according to the programmed
schedule.
• Ensure the thermostat is in Automatic mode.
• Check the clock (Time menu) and the schedule (Prog menu). If the thermostat is config-
ured for 12-hour format, ensure that AM or PM appears on the screen.
