Temperature Control
The thermostat controls the oor/ambient temperature
(according to the / mode) with a high degree of accuracy.
When the heating starts or stops, it is normal to hear a “clic”
sound. It is the noise of the relay which opens or closes, as
applicable.
Backlighting
The screen lights up when you press down a button. If you
do not press down any button for more than 15 seconds, the
screen turns off.
If you press down the + or – button once when the backlight
is off, it will light up without changing the set point value. The
set point value will change only if you press down one of these
buttons again.
Ground-fault Circuit Interrupter (GFCI)
The GFCI is designed to reduce the risk of electric shock. It
can detect a leakage current of 5mA. If a defect is detected,
the GFCI device lights up, and both screen and heating system
circuit are deactivated. The GFCI can be reinitialized either
by pressing down the Test button or by disconnecting the
thermostat at the electrical panel.
Ground-fault Circuit Interrupter (GFCI) Verification
It is important to verify the ground-fault circuit interrupter
installation and operation on a monthly basis.
GFCI verification procedure
1- Increase the temperature set point until the heating power
bars are displayed (displayed in the bottom-right hand corner
of the screen).
2- Press down the Test button.
3- The following three cases can occur:
a) Successful test: The red light indicator of the thermostat
