confirm your choice by pressing down the Mode or Day/Hr 

button. You can also press down the desired day of the week 

button without using the + or - button and confirm your choice 

using the Mode or Day/Hr button. 

3.  The two figures indicating the hour blink. You must adjust 

them using the + or - button and confirm your choice by 

pressing down the Mode or Day/Hr button. 

4.  The two figures indicating the minutes blink. You must adjust 

them using the + or - button and confirm your choice by 

pressing down the Mode or Day/Hr button. The adjustment 

is then completed and the thermostat returns to the previous 

mode.

  At any time, you can exit the adjustment mode of the day and the 

hour by pressing down the Exit button or by not pressing any 

button during 1 minute.

In case of a power failure, the thermostat is self-sufficient for 2 

hours. If the failure lasts less than 2 hours, the thermostat saves 

the adjustment of the hour and the day of the week. When the 

power is restored after an extensive failure (more than 2 hours), 

the hour and the day of the week are recovered, but you must 

update them.

Display in Degrees Fahrenheit/Celsius

The thermostat can display the ambient temperature and the set 

point in degrees Fahrenheit (standard factory setting) or Celsius.

Adjustment procedure for degrees Fahrenheit/Celsius display.

1.  To switch from the degrees Fahrenheit to the degrees Celsius, 

and conversely, simultaneously press down the + and - 

buttons for more than 3 seconds until the   icon blinks.

2.  Press down the + button to switch from the degrees Fahrenheit 

to the degrees Celsius, and conversely. The degree Fahrenheit 

or Celsius symbol is displayed.

button or do not press down any button during 5 seconds to 

exit the adjustment function.
