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:

1. Press the Mode button until Econo appears on the screen.
2. Press the Pgm button. Period 1 is displayed.
3. Press the Day button to set the start day of the displayed period.
4. Press the Hour and Min buttons to set the start time of the displayed period.
5. Press the Up or Down button to set the temperature.
6. Press the Pgm button to select Period 2.
7. Repeat steps 3 through 5 to set Period 2.
8. 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

1. Pull the cover down.
2. Briefly insert a pointed object (e.g., paperclip) through the advanced setting opening. The first parameter will appear.
3. To display the next parameter, press the Mode button.
4. To modify a parameter, press the Up or Down button.
5. To exit the menu, press the Ret button or do not press any button for 1 minute.

Parameter and options	Display and Default Setting	Parameter and options	Display and Default Setting
Temperature display format °C / °F		Time display format 24 h / 12 h
Early Start * OF (Off) / On		Automatic Daylight Saving Time ** OF (Off) / On
Year *** 00 – 99		Month *** 1 – 12
Day *** 1 – 31		Cycle length **** Std / Fan

* 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 thermostat is exposed to an air draft. The sticker on the thermostat’s screen has not been removed. The thermostat is located near or above a heat source such as a light dimmer
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.	Ensure the thermostat is in Automatic mode Check the clock and the schedule. If the thermostat is configured for a 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.
