SUPPLIED PARTS
- One (1) thermostat
- Two (2) 6-32 mounting screws
- Two (2) solderless connectors
Installation
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK.
- All cables and connections must comply with local electrical codes.
- This thermostat has tinned copper wires for line and load connections.
- Special CO/ALR solderless connectors must be used if these wires will be connected to aluminum conductors.
- Install the thermostat onto an electrical box
- Install the thermostat about 5 ft. (1.5 m) high, on an inside wall facing the heater.
- Avoid locations where there are air drafts (such as the top of a staircase or an air outlet), dead air spots (such as behind a door), or direct sunlight. · Do not install the thermostat on a wall that conceals chimneys or stove pipes.
- The thermostat wires are not polarized; either wire can be connected to the load or to the power supply.
Wiring
Connect the thermostat wires to the heating system (load) and to the power supply using solderless connectors for copper wires.
Mounting the thermostat
Loosen the screw underneath the thermostat and separate the faceplate from the wallplate.
NOTE: The screw remains captive and cannot be completely removed. Mount the wallplate to the electrical box using the provided screws. Insert the screws through the two left or the two right mounting holes of the wallplate. Reinstall the faceplate onto the wallplate and tighten the screw underneath the thermostat.
NOTE: If there is a protective film or sticker on the thermostat’s screen, peel it off. Apply power to the heating system. Verify the installation by checking that the heating system can be turned On by raising the setpoint using the Up button or turned Off by lowering the setpoint using the Down button.
WARNING
Keep the thermostat’s air vents clean and free from obstructions.
Controls
Display
Clock and day setting
The clock must be set when Time appears on the screen.
- Pull the cover down.
- Press the Day button to set the day.
- Use the Hour and Min buttons to set the clock.
- Press the Ret button to exit.
Temperature display and setting
The thermostat normally displays the room (measured) temperature.

- To change the setpoint temperature, press the Up or Down button repeatedly until the desired temperature is displayed.
- The screen is backlit for 12 seconds when any button is pressed.
Automatic mode
To place the thermostat in Automatic mode, press the Mode button until Auto appears on the screen. The current period number also appears.
In this mode, the thermostat follows the programmed schedule. You can program up to 4 periods 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).
By default, the thermostat is programmed with the following schedule:
| Monday to Friday | Saturday & Sunday | ||||
| Period | Start Time | Temperature | Start Time | Temperature | |
| 1 | Wake | 6:00 | 21.0 °C (70 °F) | 6:00 | 21.0 °C (70 °F) |
| 2 | Leave | 8:00 | 16.5 °C (62 °F) | –:– | – – |
| 3 | Return | 18:00 | 21.0 °C (70 °F) | –:– | – – |
| 4 | Sleep | 22:00 | 16.5 °C (62 °F) | 22:00 | 16.5 °C (62 °F) |
Temporary Override
You can temporarily override the current temperature using the Up or Down button. The new setpoint will be used until the end of the current period. During the override, Auto flashes on the screen.
To modify the schedule:
- Press the Mode button until Auto appears on the screen.
- Press the Pgm button. Period 1 of the weekday (Monday to Friday) program is displayed.
- To display another period, press the Pgm button.
- To toggle between the weekday (Mon to Fri) program and the weekend (Sat & Sun) program, press the Day button.
- Press the Hour and Min buttons to set the start time of the displayed period.
NOTE: To cancel the period, press the Mode button. The thermostat will display –:–. During operation, the thermostat will skip over that period. - Press the Up or Down button to set the temperature of the displayed period.
- Repeat steps 3 through 6 to set another period
- Press the Ret button to end programming.
Manual mode (a permanent override of schedule)
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 must be done manually. Press the Up or Down button to set the temperature. The default setting is 21°C (70°F).
Economy mode
To place the thermostat in Economy mode, press the Mode button until Econo appears on the screen. This mode is ideal for weekend residences (cottages) as it can be used to keep the temperature at an economy level during most of your absence and raise the temperature to a comfortable level by your usual arrival time. If you do not show up at your cottage, the temperature will return to the economic level until the following weekend.
| Period | Temperature | Start Time |
| 1 | Set to a comfortable level (e.g., 22°C). | Set the day and time that you want the temperature to start rising so that the comfort level is reached by the time you arrive (e.g., Friday at 3:00 pm). |
| 2 | Set to an economical level (e.g., 16.5°C). | Set the day and time that you want the temperature to start dropping to the economy level if you do not show up (e.g., Friday at 8:00 pm). |
The Economy mode can be used as follows:
- Place the thermostat in Economy mode during your absence.
- When you arrive, place the thermostat in Automatic mode or in Manual mode before the temperature drops to the economic level.
- When you leave, switch the thermostat back to Economy mode.
To program the two periods of the Economy mode:
- Press the Mode button until Econo appears on the screen.
- Press the Pgm button. Period 1 is displayed.
- Press the Day button to set the start day of the displayed period.
- Press the Hour and Min buttons to set the start time of the displayed period.
- Press the Up or Down button to set the temperature.
- Press the Pgm button to select Period 2.
- Repeat steps 3 through 5 to set Period 2.
- Press the Ret button to end programming.
Temporary Override
You can temporarily override the current temperature using the Up or Down button. The new setpoint will be used until the end of the current period. Econo flashes during the override.
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.
Advanced settings
- Pull the cover down.
- Briefly insert a pointed object (e.g., paperclip) through the advanced setting opening. The first parameter will appear.
- To display the next parameter, press the Mode button.
- To modify a parameter, press the Up or Down button.
- To exit the menu, press the Ret button or do not press any button for 1 minute.

* 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 be reached at the beginning of periods 1 and 3. When Early Start is disabled (Off), heating does not start in advance, and therefore the desired temperature will not yet be reached at the beginning of these periods.
** When Automatic Daylight Saving Time 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.
*** Available only if Daylight Saving Time is enabled (On).
**** Generally set to a 15-second cycle (Std) as it provides better temperature control. However, set it to a 5-minute cycle (Fan) if you have a fan-forced heater to prevent premature fan motor burnout. Fan appears on the thermostat’s screen when the 5-minute cycle is selected.
Troubleshooting
| Problem | Solution(s) |
| The thermostat’s housing is hot. | This condition is normal. Ensure that the heater capacity does not exceed the thermostat’s maximum load. |
| The wrong temperature is displayed. | Correct it if any of the following situations exists:
|
| The wrong time is displayed | The time is not yet set or the thermostat was without power for more than 5 hours. |
| Temperature does not change according to the programmed schedule. |
|
| 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. |
