3. ADVANCE START-UP OF THE HEATING SYSTEM/ SUMMER MODE
Select one of the following modes using the
+/- T
buttons
and confirm it with the
i
button.
Option 0
=
normal mode
Normal operation of the heating system, without advance start-up of the heating.
Option 1
=
switch on the heating early
This function will guarantee the required temperature at the required time.
You don’t need to consider when to switch on the heating so that it is warm when you get up
and yet ensure the heating is not used unnecessarily for a long time in advance. All you need
to do is programme when you wish to have the required temperature. BPT-SP will find the heat
constants of the room within two days and then it will switch on the heating in advance
accordingly. The period for this early start-up is limited to 2 hours.
Option 2
=
summer mode
In this mode, the heating is prevented from switching on. It is used mainly in the summer
period when heating is not required. After the activation of this mode, the symbol "
Ñ
" will
appear on the display.
Note:
The non-freeze protection ( 3° C ) remains functional.
In this mode, the temperature
cannot be changed and the holiday mode cannot be set!
4. THE MINIMUM TIME OF OPERATION OF THE HEATING APPLIANCE DURING
HYSTERESIS
