Following items are shown on the main screen : 

 

the day of the week (intermittent if not updated) 

 

the current time (intermittent if not updated) 

 

the temperature measured (measurement every 10sec) 

 

an icon indicating the function of  the active thermoregulation 

(automatic, manual, summer or standby)  

 

 

Automatic 

Temperature control environment 
according to the weekly program 

set by the user. Program seen as a 
graph of the current day. 

 

Manual

Temperature control environment in 
accordance with user‐selected temperature 

(thermostat function) 

 

Summer 

Temperature control environment 

disable. Summer ventilation can be 
activated manually. 

 

Standby

Temperature control environment disable.

(no frost protection) 

 

In automatic mode, the chronothermostat performs the temperature control program as set for the current day. The 
graph is visible at the bottom of the display.The graph is divided into time intervals of 15 minutes, corresponding to a 

pixel horizontally and appearing in the four programmable temperature levels. 

 
Near the icon of the operation mode, other icons may appear, meaning following. 

 

Indicates that heater is turned on (the size of the symbol depends on the modulation level of the flame

 

Lockout of the heater

 

Fault 

Connection icon symbol  (if no icon appears)

(P.S : if heater is in standby mode and has no problem, no icon will appear)

 

 
In addition, under  

the room temperature  

indication, a text may
