Installing a room thermostat will optimise the installation’s performance, adapting the heating to the 

requirements of your home and obtaining enhanced comfort. Also, if the thermostat allows the hours 

of functioning to be programmed (chronothermostat), it can adapt the heating system to the hours 
of use of the installation.

Keypad block function 

This function protects the control panel from being accidentally or erroneously pressed while it is 

being cleaned, by children or by unauthorised persons. When this function is enabled, the electronic 

control will not react when any of the symbols or touch buttons on the control panel are pressed. 

To lock the keypad, keep your finger on the RESET touch button 
for 5 seconds. The word "

LOC

" will flash on the display until the 

control panel is unlocked again. 

To unlock the keypad, place your finger on the RESET touch 

button again for 5 seconds. The display will then return to its 

normal status.
