Hybrid Compact description

The HYBRID COMPACT system consists of the following
components :
- A heat pump,
- A "Compact" hydraulic module,
- A boiler,
- The Systempro control unit,
- A wireless outdoor sensor,
- A wireless or wired room thermostat.

Operating principle of the system

The home's heat is generated by either the heat pump or the
boiler. The heat emitters can also be low temperature (underfl oor
heating, ...) or high temperature (radiators...). In order to always
provide the best compromise between comfort and economy,
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.
The software in the Systempro control unit constantly monitors
outdoor temperature, and the co-effi cient of Performance (COP).
When the outside temperature is mild and/or the heating water
temperature is low, the COP is high and the heat pump is very
effi cient. However, the COP drops signifi cantly when the outside
temperature is cold and/or the heating temperature request is
hotter. Thus, the electrical consumption of the heat pump can
become signifi cant in winter. It then becomes more advantageous
to operate the boiler as its operating cost will be lower.
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 or heat pump
alone). The appliances cannot 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).
