13. EARLY SWITCHING ON THE HEATING

It is used to correct the temperature measured by the thermostat. The setting must be made only after 12 hours of 

operation, when the temperature of the internal sensor stabilizes. Measure the room temperature with a thermo-

meter, if the temperature differs from the temperature on the thermostat, set 

the correction between -5 ° C and + 

5 ° C.

By turning the button “   “ set YES / NO and confirm withthe button  “   “.

This function guarantees you the desired temperature at the desired time. You don‘t have to think about when to 
turn on the heating so that it gets warm in the morning when you get up and it doesn‘t heat unnecessarily long in 
advance. Just set the temperature program in Prog mode and activate this function. During two days of operation, 
the thermostat determines the thermal constants of the room and then switches on the heating well in advance. 
The early switch-on time is limited to maximum 2 hours

By turning the button “   “ set YES / NO and confirm with the button “   “.

Heating on is not allowed in this mode. The use is mainly during the summer, when it is not necessary to drown. 

After activating this mode, the symbol appears on the display“        “.

Note

: frost protection (3 ° C) and DHW functions are still functional. You cannot change the temperature and set the 

holiday mode in this mode!

By turning the button “   “ set YES / NO and confirm withthe button “   “.

If „YES“ is selected, the PrU and PrL programs will be switched automatically, depending on the week (even / odd). 

This setting is advantageous, for example, during shift operation (every week there are different requirements for 

thermal comfort in the building).

By turning the button “   “ set YES / NO and confirm withthe button “   “.

gsm module enabled, it is necessary to set CONST 19, 20!

By turning the button “   “ set YES / NO and confirm with the button “   “.

This constant can be set if CONST18 = YES, thus determining the possibility of connecting a GSM modu-

le for control by a mobile phone.

SMS messages about the thermostat status are to be sent.

By turning the button “   “ set the phone one by one. number, confirm each setting with the button “   “.

This constant can be set if CONST18 = YES, thus determining the possibility of connecting a GSM mo-

dule for control by a mobile phone. 

We set the PIN code of the SIM card, which is inserted into the 

GST1 or GST2 module.

By turning the button “   “ set 4 numbers one after the other, confirm each setting with the button “   “.
