In this screen position we can see the total 
operation hours of the burner or the cooling 
unit. This  value  can  not  be  altered  by  the 
keypad  but  can  be  reset  if  the  battery  is 
removed.  the  maximum  value  is  9.999 
hours.

SELECTING THE FACTORY DEFAULT 
SETTINGS.

If for any reason there is the need to restore 
the thermostat to its factory default settings 
then  this  setting  will  restore  then  is  we 
select       and press the key      .This does 
not affect the time and date settings.
The factory default setting is        .

11. CHANGING THE BATTERY

When  the  screen  shows  the          symbol             
the unit warns use that the batteries have 
limited  energy  and  that  they  must  be 
replaced in the next 3 weeks. To replace the 
batteries simple remove the cover (Fig. 2) 
to  expose  the  battery  compartment. 
Remove  the  batteries  and  within  30 
seconds reinsert new ones in order to avoid 
a reset of the device. Should this happen it 
will  require  to  adjust  the  time  and  date 
again. All other setting remain unaffected.   
Avoid  replacing  the  batteries  with  the 
backlight  activated,  /this  will  immediately 
reset the device and the hour meter. Take 
care of the battery orientation and insert the 
new  batteries  according  to  the  graphic 
representation etched on the plastic base. 
The  reverse  installation  will  not  harm  the 
device but it will not permit it to operate.
The battery life time has been design to be 
approximately  2  years.  Factors  that 
influence the battery life are prolong use of 
the  keyboard  with  the  backlight  active, 
increased temperature and humidity as well 
as battery quality. 

12. ANTI-ICE PROTECTION

If  the  room  temperature  in  which  the 
thermostat is installed falls below  5°C, the 
unit activates the burner output irrelevant of 
the  ON  or  OFF  state  of  the  thermostat  to 
prevent ice build up. The burner output is 
active  for  as  long  as  the  temperature  is 
below 5°C.

13. CLEANING THE THERMOSTAT

To  clean  the  device  use  a  damp  cloth  to 
remove any dust or stains from the covers. 
Do not use any liquid or dissolvers that will 
damage the plastic covers.
