VI.f) Additional pump settings
Additional pump settings enable the user to select the type of additional pump : fl oor pump
/ DHW pump. The type of pump infl uences the range of temperature settings and protections
in case of alarms.
In the case of DHW pump, the user may change its activation temperature. It is the
threshold temperature at which the pump is enabled (the temperature measured by
additional sensor). The pump remains active until the temperature reaches the pre-set
value. Additionally, the user may adjust hysteresis of additional pump if DHW pump is
selected. In the case of fl oor pump, the user may preset the minimum temperature of the
sensor which is necessary for pump activation and the maximum temperature above which
the fl oor pump is disabled.
