3.23 OPERATING LOGIC

Central heating mode
Following a request during the room heating mode, the electronics decide, according to the external temperature, whether to activate the
outdoor unit, or (with cold temperatures) the indoor unit (Fig. 68 - 69).
The management electronics select which heat source to be used according to the combination of the parameters set in the integration
menu of the control panel. The indoor unit may activate when the external conditions are favourable to the operation of the outdoor unit;
this may happen after a time proportional to the "Heat. waiting time" parameter.
Alternatively, a fixed outside switching temperature can be set (manual mode in parameter "Integration mode" by setting the tempera-
ture with "Manual activation temp."). The DHW demand is met by the indoor unit (when combined with a storage tank unit) in priority
mode over a possible room central heating demand.
Operation in DHW mode (when combined with a storage tank unit).
