Display in degrees Fahrenheit/Celsius
The thermostat can display the ambient temperature and the set
point in degrees Fahrenheit (standard factory setting) or Celsius.
Selection procedure for degrees Fahrenheit/Celsius display.
1. From the Day mode, simultaneously press down the (+) and
(-) buttons for more than 3 seconds. Then, the set point will
blink. Release the buttons.
2. Press down the (+) button to switch from the degrees
Fahrenheit to the degrees Celsius, and conversely. The
degrees Fahrenheit (F) or Celsius (C) symbol will be displayed.
3. When the adjustment is completed, release the buttons and
wait for 5 seconds to exit the adjustment function.
Temperature control
The thermostat controls the temperature of the ambient air
with precision. When the heating comes on or shuts off, it is
normal to hear a ‘‘click’’ sound. This noise is caused by the relay
opening or closing, depending on the situation.
• If the ambient temperature is 2.7°F below the set point, duty
cycle is set at 100 %.
• If the ambient temperature is 2.7°F over the set point, duty
cycle is set at 0%.
• If the ambient temperature is between: [SetPoint – 2.7°F,
SetPoint + 2.7°F}, duty cycle is given by a PI (proportional-
integral) control.
Red Indicator
When the heating comes on, the heating red indicator lights-up.
