solid fuel boiler temprature is exceeded, circulation pump
in solar system will activate although d. h. w. temperature
is already reached.

S6.4 COLLECTOR’S FROST
PROTECTION
If the temperature drops bellow the set point value (S6.5),
the solar pump switches -on to prevent freezing in the
collectors and pipelines.
NOTE: This setting is suitable only for climates areas
where the temperature only occasionally drops bellow the
freezing point.
