time has elapsed, the

buttons on the 

front panel of the device, and then press the “

HOLD

” button and hold it down 

for at least 2 seconds. At this time, the 

 icon appears on the display, along 

with the   notice in place of the time characters, which indicates the duration 

of modification in days. Adjust this time to the desired length (between 1 and 

99) using the large

 

and

 

 

buttons (1 day means 24 hours). The 

holiday program will start approximately 10 seconds after the adjustment. 

Following this, the device will keep the modified temperature for the given 

period of time. The adjusted temperature can be freely changed during the 

holiday program without exiting it. 

During this temporary modification, the segments indicating the time on the 

display alternately show the exact time

 icon disappears and the device resumes the program that has been

modification has expired, please press the “

SET

” button.

4.4 Temperature modification until the next manual interference 

Set the required temperature using the large

 

 

and

 

 

buttons on the 

front panel of the device. At this time, the 

 

icon appears on the display, 

indicating that the thermostat is operated with manual control. Then, press the 

HOLD

” button briefly, after which the

 

 

icon appears and the 

 

  icon 

disappears. The device will then control the boiler according to the set value 

until the next manual interference. During this time, the thermostat acts exactly 

the same way as a non-programmable thermostat. The adjusted temperature 

can be freely changed during this temporary modification without exiting it.

If you wish to return to the set program, please press the “

SET

” button.

When you press the “

” button, the background light of the display will 

turn on for 15 seconds. When you press another button while the display 

is illuminated, the background light will turn off only after 15 seconds have 

elapsed since the last button had been pushed.

6. LOCKING THE CONTROL BUTTONS

The thermostat enables you to lock its control buttons. With this function, you 

can prevent unauthorised modification of the program or the set temperature.
