Operating principle of the system

The heating appliances consists of a heat pump and a hydraulic
module. The heat emitters can also be low temperature
(underfl oor heating, ...) or medium temperature (radiators...). In
order to always obtain the best comfort/economy trade-off , one
of the two heat appliances supplies the heating installation with
hot water at the temperature necessary to obtain the desired
ambient temperature. This depends on the outside temperature
measured by the wireless outside sensor continually corrected
by the real temperature measured by the wired or wireless room
thermostat.
When the heat pump power is not suffi cient to provide heating
but its operation remains economically advantageous, the boiler
can operate simultaneously guaranteeing optimum usage of
the heat pump and therefore the operating cost of the system.
If the boiler installed in the system communicates by e-BUS
(schemes "10" or "11"), you then have modulating control of
your boiler in accordance with your system. In the case of a boiler
operating in On/Off mode (schemes "3", "6" or "13"), you then
have fi xed control independent of your existing boiler (oil, wood,
competitor...) without communication with your system (the
boiler reacts to a fi xed setting on its control panel).
The changeover point between the heat pump and the boiler is
managed automatically, depending on the outside and ambient
temperatures. This continually guarantees the operation of the
appliances with the best operating cost (boiler alone, heat pump
and boiler or heat pump alone). The appliances can operate
simultaneously. Therefore, the system always uses the cheapest
solution.
The switchover point must be determined in accordance with
the respective energy costs (see the "Activation of control unit
Settings> Energy management" chapter).
