- Page 2 WARNING WARNING Before installing and operating this product, the owner and/or installer must read, understand and follow these instructions and keep them handy for future reference. If these instructions are not followed, the warranty will be considered null and void and the manufacturer deems no further responsibility for this product.
- Page 3 1. Description This thermostat can be used to control electric heating units such as electric baseboards, convectors, or aeroconvectors. It keeps the temperature of a room at the requested set point with a high degree of accuracy. This product is designed for installations with electrical current - with a resistive load - ranging from 1.25 A to 12.5 A (120/240 VAC).
- Page 4 2. Installation Selection of the thermostat location The thermostat must be mounted on a connection box on a wall facing the heating unit, at around 1.5 m (5 feet) above the floor level, on a section of the wall exempt from pipes or air ducts. Do not install the thermostat in a location where temperature measurements could be altered.
- Page 5 3. Using a screwdriver, loosen the screw retaining the mounting base of the thermostat until you feel a loose (do not completely remove the screw). Then, remove the mounting base at the back of the thermostat by tilting it downward, then towards you. 4.
- Page 6 5. Take the wires from the wall through the hole at the base of the mounting base and connect them using the supplied solderless connectors. When making the connection with aluminum wire, make sure that you are using connectors identified CO/ALR. Please note that the thermostat wires do not have polarity. Therefore, the way they are connected is not important.
- Page 7 6. Place all the wires into the connection box. 7. Align the little slots located on the top of the thermostat with those on the the mounting base and secure the thermostat to the mounting base. Note that you can also position the thermostat on the left or the right side of the junction box (see the illustrations below).

3. Operation ambient temperature/ timer heating power used indicator pictograms fan mode frost-free warning automatic mode day mode lock mode night mode top button bottom button Powering on for the first time When powering on for the first time, the thermostat is initially set to Day mode The temperature is displayed in Celsius and is set at 21 degrees by default. - Page 9 To adjust the set point, just press down the top button to increase the value, or the bottom button to decrease it. Set points can be adjusted by increments of 0.5°C (1°F). To quickly scroll through the set point values, press and hold down the button. The minimum set point is 3°C (37°F), and the maximum set point is 30°C (86°F).
- Page 10 Night mode timer The Night mode features a timer that automatically returns to the Day mode after a selectable time period. This timer allows the temporary use of a temperature set point. The standard factory adjustment of the timer is 8 hours. With this adjustment, the thermostat automatically returns to Day mode 8 hours after being switched to the Night mode.

Page 11: Automatic Mode
NOTE: The Night mode timer will be automatically reinitialized to the latest recorded value when switching from the Day mode to the Night mode. It is not necessary to readjust the timer every time you switch to the Night mode. The timer is also reinitialized when this value is adjusted. - Page 12 Adjustment procedure of the Automatic mode 1. If necessary, adjust the Day/Night set point at the desired temperatures. If needed, switch from one mode to the other by simultaneously pressing down the two buttons and releasing them immediately. 2. From the Night mode, simultaneously press down the two buttons for more than 3 seconds.
- Page 13 NOTE: It is always possible to manually change the Day/ Night mode during a 24-hour cycle. However, any manual return to the Night mode will re-initialize the Night mode timer to the latest value recorded, which modifies the cycle in progress. In all cases, at the end of the 24-hour cycle, the thermostat will return to the Night mode and start a new cycle.
- Page 14 Display in degrees Celsius/Fahrenheit The thermostat can display the ambient temperature and the set point in degrees Celsius (standard factory setting) or Fahrenheit. Selection procedure for degree Celsius/Fahrenheit display (for model with backlight) 1. From the Day mode, simultaneously press down the two buttons for 8 seconds (note that the backlight will blink after 3 seconds, but you must hold down the buttons).
- Page 15 The level of power used to maintain the temperature at the set point is expressed as a percentage indicated by the number of bars in the thermometer displayed. The heating power used is displayed as follows: 4 bars = 75% to 100% 3 bars = 50% to 75% 2 bars = 25% to 50% 1 bar = 1% to 25%...
- Page 16 2. From the Day mode, simultaneously press down the two buttons for more than 13 seconds, until the Lock icon displays (note that the backlight will blink after 3 seconds and the °C or °F symbol will appear after 8 seconds, but continue to keep both buttons pressed down).
- Page 17 Fan mode The activation of the Fan mode is similar to the Celsius/ Fahrenheit adjustment. Procedure to activate/deactivate the Fan mode (for model with backlight) To activate or deactivate the Fan mode, you must press down both buttons simultaneously for 8 seconds while in Day mode. Once the 8 seconds have passed, the Celsius/Fahrenheit symbol will blink.
- Page 18 When the Fan mode is activated, the stop or minimum heating time (OFF/ON) for a complete 10 minute cycle is established at 90 seconds (factory setting). You can adjust it from 90 to 300 seconds. This is done to limit the amount of times the thermostat will turn on or off.
- Page 19 Please note that the automatization of the Day/Night modes is not automatically reactivated when thermostat is turned on. The icon of the Automatic mode blinks to warn the user that the mode was previously activated when thermostat was shut off but is no longer active. Furthermore, when power is shut off, the existing Day/ Night mode is recovered only if the Automatic mode was previously deactivated.
