11 DHW recirculation pump
The DHW recirculation pump ensures a constant supply of hot water to the taps.
It is automatically activated with DHW heating and the pump runs in intermittent
or continuous mode if at least one heating circuit is in normal heating mode (day
mode), or if DHW heating is in day mode.
The DHW recirculation pump runs continuously in the "ON" position.
The factory default is "2", i.e. 2 pump runs per hour, running for 3 minutes each
time (Fig. 10).
The intermittent mode may be set to 1 to 6 pump starts per hour in order to
minimize the operating costs of the recirculation pump. This setting saves
energy while ensuring comfort.
