Programmable
Thermostat
Application
This thermostat is designed to control an electric heating system such as a baseboard
heater, a radiant ceiling, a convector or a fan-forced heater.
The thermostat CANNOT be used with:
• a resistive load under 0.83 A
• a resistive load over 14.6 A
• a system driven by a contactor or a relay (inductive load)
• a central heating system.
WARNING Electrical Shock Hazard.
This thermostat is a line voltage control (120240 Volts). Do not install it if you
are not completely familiar with house wiring. If handled improperly, there is risk
of electric shock hazard, which may cause serious injury or death.
Do you need assistance? We are here to help.
Call 18008312823 for wiring assistance before returning the
thermostat to the store.

Automatic mode
In Automatic mode, the thermostat adjusts its temperature setpoint
according to the period of the day. To place the thermostat in this
mode, press the Mode button until Auto appears on the screen. The
current period name also appears (unless the thermostat has not
been programmed with a schedule).
You can program up to 4 periods (Wake, Leave, Return or Sleep) in a day. You
can set 2 different programs: one for the weekdays (Monday to Friday) and
another one for the weekend (Saturday and Sunday).
The thermostat uses the following default schedule:
Monday to Friday Saturday & Sunday
Period Start Time Temperature Start Time Temperature
Wake 6:00 am 70°F (21.0°C) 6:00 am 70°F (21.0°C)
Leave 8:00 am 62°F (16.5°C) --:-- - -
Return 6:00 pm 70°F (21.0°C) --:-- - -
Sleep 10:00 pm 62°F (16.5°C) 10:00 pm 62°F (16.5°C)
Temporary Override
You can temporarily modify the setpoint temperature while the thermostat is
in Automatic mode using the Up or Down button. The new setpoint will be used
until the beginning of the next period. During the override, Auto flashes on the
screen. You can cancel the override by pressing the button.

6
Manual (Man) mode
To place the thermostat in Manual mode, press the Mode button
until Man appears on the screen. In this mode, any modification
to the temperature setpoint must be done manually. To set the
temperature, press the Up or Down button. The default setting is 70°F
(21.0°C).
Away mode
To place the thermostat in Away mode, press the Mode button until
Away appears on the screen. This mode is a quick way to lower the
temperature to a predetermined setting before you go away for
an extended length of time. The temperature is 59 °F (15.0 °C) by
default and can be modified using the setup menu (see page 7).
Standby mode
To disable heating, press the Mode button until Standby appears on the
screen. In this mode, the setpoint temperature cannot be displayed
or modified. For frost protection, heating will turn on only to prevent
the room temperature from dropping below 41 °F (5 °C).
2. Press the Hour and Min buttons to set the
start time of the displayed period.
NOTE: To cancel the period, press the Mode button.
Instead of displaying the start time of the period, the
thermostat will display --:--. During operation, the
thermostat will skip over that period.
3. Press the Up or Down button to set the
temperature.
4. To set another period, press the Pgm button
and repeat steps 2 and 3.
5. Press the button to return to normal
display.
To modify the schedule:
1. Press the Pgm button. Each time you press the Pgm button, the thermostat
displays one of the periods of the schedule in the following order:

fan-forced heater.

Set the temperature you wish to use when the thermostat is in Away mode
(see page 6).
3Daylight Saving Time
When the Daylight Saving Time function is enabled (On), the thermostat au-
tomatically switches to Daylight Saving Time on the second Sunday of March
and to normal time on the first Sunday of November.
4Year, Month, Day
These parameters are available only if the Daylight Saving Time function is
enabled (On).
5Early 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 peri-
ods; thus there is a delay before you reach the desired temperature.
6Keypad lock
The settings are locked. The temperature adjustment buttons only allow you
to view the temperature setpoint.
Troubleshooting
Your thermostat requires little or no attention. Most problems can generally
be traced to the following:
Problem Solution(s)
Thermostat is hot. This condition is normal. Ensure that the heater capacity does not
exceed the thermostat’s maximum load.
Wrong temperature is
displayed.
Correct it if any of the following situations exists:
• The thermostat is exposed to an air draft.
• The thermostat is located near or above a heat source such as a
light dimmer
Wrong time is displayed. The thermostat was without power for more than 5 hours.
Temperature does not
change according to the
programmed schedule.
Check that the thermostat is in Automatic mode.
Check the schedule and clock settings. If the thermostat is
configured in 12-hour format, ensure that PM appears on the screen
when afternoon times are displayed.
LP appears on the
screen or the screen is
blank despite there is no
power outage.
The thermal circuit breaker in the heater is opened.
This can happen if the heater is obstructed by furniture or curtain
and has overheated, or if the thermal circuit breaker is defective or
too sensitive.
The settings cannot be
changed.
The settings are locked (see page 7).

9
LO is displayed The measured temperature is below the display range. Heating is
activated.
HI is displayed The measured temperature is above the display range.
E1, E2 is displayed The thermostat performance is reduced due to a sensor error. Please
contact technical support for more information.
Resetting the thermostat (default settings)
NOTE: All parameters, except the clock (time and day), return to their default
settings when the thermostat is reset.
1. Press the Mode button until Standby appears on the screen.
2. Press the button for 6 seconds.
3. The thermostat will display rSt (reset) for 2 seconds to indicate it is reset
and will then return to normal display.
Power outage
During a power outage, the thermostat display remains lit for the first 2
minutes. During this time, the LP (low power) indicator appears and all
buttons are disabled. Then the screen turns blank. The settings are stored
in memory. When power returns, the thermostat returns to the mode of
operation preceding the power outage. If the power failure has exceeded 5
hours, the clock and date must be re-adjusted.
