3.10 CENTRAL HEATING OPERATION IN
COMBINATION WITH THE HEAT
PUMP.
Following a request during the room heating
mode, the electronics decide, according to the
external temperature, whether to activate the
heat pump, or (with cold or high temperatures)
the boiler (fig. 3-6).
Boiler and heat pump can even operate
simultaneously: in fact, if only the heat pump
is active, but it cannot bring the water to
temperature within a certain time, the boiler
starts in parallel.
The boiler electronics select which heat source
to be used according to the combination of
“MAGIS” parameters.
The heating mode is equipped with a timer
that prevents the generators from restarting
too frequently. One can modify this value via
parameter “P69”. The heat pump is equipped
with its own timer that that prevents the frequent
start-ups, set at a fixed value (3 minutes).
Values Te1 and Te2 are determined by the logic of the boiler board
