AUTO:

 

the 

thermostat 

uses 

the 

programmed  heating  pattern  (default  or 
user  defined)  to  switch  the  heating  ON  & 
OFF at preselected times. 

 

OFF:

  the  thermostat  is  set  to  have  the 

heating  constantly  OFF  (in  this  mode  the 
default  or  user  defined  heating  pattern  is 
ignored) – summer mode. 

 

PARTY:

  the  thermostat  is  set  to  provide 

heating  constantly  ON  (in  this  mode  the 
default  or  user  defined  heating  pattern  is 
ignored).  This  status  stay  ON  up  to  end 
user switching OFF 

 

ADVANCE:

  the  pre-programmed  heating 

pattern  is  advanced  to  the  next  ON  (or 
OFF) period (this function can only be used 
when the clock is in the AUTO mode)

ORKING  MODE

:

  This  central  heating  control  device  provides 

you  both  the  room  thermostat  function  and  the  weekly  clock 
function.  When  in  AUTO  mode,  the  central  heating  will  be 
ON/OFF according to the programmed times and according to 
the set

 

comfort temperature (the ON command is identified by 

the flame icon). When the heating will be commanded ON the 
set-point  in  the  room  will  be  the  comfort  one.  In  case

 

of  off 

programmed  times,  the  set  temperature  is  the  “economy 
temperature”,  selectable  inside  the  main  menu  (16°C  is  the 
default value). When in OFF mode the heating requested will 
be  switched  on  when  the  room  temperature  drops  under  the 
frost  protection  value  (default  is  5°C);  this  value  can  be 
modified inside the technical menu. When in PARTY mode the 
heating  request  is  permanently  on  according  the  selected 
comfort temperature that can be modified any time rotating the 
encoder and pressing to confirm. 

 
E

NCODER

 

The  encoder  has  three  functions:  selection  of  the  set 
temperature,  set  the  ADVANCE  function  and  setting  the 
thermostat.  If  the  status  mode  of  the  thermostat  is  OFF,  only 
the pressing functionality is active; any rotation done does not 
generate any modification.
