4.2.5. Changing the forced pump operation mode
Press the "
B
" button under the temperature setting. The digits begin to
blink and indicate the value of the current setting (left indicator). When
the "
B
" button is pressed again, the right temperature indicator starts
blinking. Press the "
B
" button again in order to edit the hysteresis (
HI
)
value of the left indicator. Press the "
B
" one more time in order to set the
hysteresis (
HI
) value of the right indicator.
After you press the "
B
" button one more time, the value of 85°C will be
displayed in the temperature section and on the right side of the display
the symbol of forced pump operation ( ) will be shown. The "+" or "-"
button can be used to make the pump work in a continuous manner ( ) or
stop ( ) after the temperature of 85°C is exceeded. Also, the "+" or "-"
button can be used to set the maximum value, equal to 55°C, which, when
exceeded, will cause the CH pump to stop (e.g. in the case of floor
heating).
The operation of the valve or the second CH pump can be set in the same
manner. After the operation mode is set, it must be confirmed (within 10
seconds) by pressing the "
OK
" button. Otherwise, the changed setting
will not be saved and the controller will return to the previous setting.

4.2.6. Automatic operation
The controller starts or stops the pump and the valve depending on the
set temperature value. In the CH system, the pump and the valve are
started when the temperature in the location of the sensor exceeds the
set value and stopped when the temperature drops below the value set
in the controller, taking into account the hysteresis.
