The screen is backlit for 12 seconds when you press any button.
To display the set temperature (setpoint), press the Up or Down button once. The thermostat will display the setpoint instead of the clock for 5 seconds.
TURN OFF POWER TO THE HEATING SYSTEM AT THE MAIN POWER PANEL TO AVOID ELECTRICAL SHOCK.
Connect the thermostat wires to the power and to the load using solderless connectors for copper wires.
Push the excess wires back inside the electrical box. Secure the thermostat to the electrical box using the provided screws. Insert the screws through either the right or left pair of mounting holes on 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 heater can be turned on by raising the setpoint using the Up button and off by lowering the setpoint using the Down button.
WARNING: Keep the thermostat’s air vents clean and free from obstructions.
In Automatic mode, the thermostat adjusts its temperature set-point 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 ther-mostat 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 | 21.0°C (70°F) | 6:00 | 21.0°C (70°F) |
Leave | 8:00 | 16.5°C (62°F) | –:– | – – |
Return | 18:00 | 21.0°C (70°F) | –:– | – – |
Sleep | 22:00 | 16.5°C (62°F) | 22:00 | 16.5°C (62°F) |
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
To modify the schedule:
Weekdays (MO TU WE TH FR) | Weekend (SA SU) | ||||||

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 21.0°C (70°F).
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 15.0°C (59°F) by default and can be modified using the setup menu (see page 11).
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 5°C (41°F).

PROBLEM | SOLUTIONS |
Thermostat is hot. | This condition is normal. Ensure that the heater capac-ity 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. See page 7 to set time. |
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 thermo-stat is configured in 12-hour format, ensure that PM appears on the screen when afternoon times are dis-played. |
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 13). |
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)
WARNING: All parameters, except the clock (time and day), return to their default settings when the thermostat is reset.
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.
