2.1.1 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.

2.1 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.

The switchover point must be determined in accordance with the respective energy costs (see the "Activation of control unit > Settings> Energy management" chapter).

Application conditions

- The Systempro control unit manages the operation of the boiler, the heat pump and the module.

- The hydraulic connections to the boiler must be suitable for its characteristics.

- The room thermostats compatible with the system are the Climapro the Climapro1 for the “wired” version.

- Installation must have a wireless outdoor sensor.

- Connect the heat pump e-BUS directly to the control box respecting the polarity (+/-).

- The installation consists of an e-BUS heat pump and boiler. An e-BUS interface must be connected between the boiler and the control box. It is only compatible with e-BUS boilers. Refer to the e-BUS interface documentation for the electrical connection and setting of the code wheel (e-BUS address “3”).

- The hydraulic module has a plate heat exchanger for hydraulic decoupling. It is possible to have glycol water circulate only in the heat pump circuit.

RF or the Climapro1 RF for “wireless” versions and

- The overheating safety must be connected according to the standards in force (on the boiler or the circulation pump).

- The installation can be performed with a low-temperature underﬂ oor heating (heating outlet temperature < 50°C) or low temperature radiators (heating outlet temperature < 70°C).

3.1.1 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 installation can be performed with a low-temperature underﬂ oor heating (heating outlet temperature < 50°C) or low temperature radiators (heating outlet temperature < 70°C).

Application conditions

- The Systempro control unit manages the operation of the boiler, the heat pump and the module.

- The hydraulic connections to the boiler must be suitable for its characteristics.

In the case of an existing boiler without external sensor:

Increase the boiler heating outlet temperature by 5°C.

Ensure that the heating outlet temperature does not exceed 70°C (50°C

in the case of a underﬂ oor heating).

In the case of an existing boiler with external sensor:

4 Standalone

When the power of the heat pump is no longer adequate to ensure heating, the self-controlled electric heater in the hydraulic module can operate simultaneously in steps of 2 kW up to a power of 6 kW in the case of a heat pump ≤ 5 kW the back-up power is limited to 4 kW when the heat pump is operating. This guarantees optimal use of the heat pump while guaranteeing that the total electrical power consumption will never exceed 6kW (in order to optimise the electric subscription of the habitation). When the heat pump is not operating, the electric heater can reach a power level of 6kW independent of the outside temperature conditions.

The changeover point between the heat pump and the electric heater is managed automatically, depending on the outside and ambient temperatures. Thus, the system always optimises the use of the heat pump with respect to the electric back-up heater.

Avoid programmes with high temperature variations

in the case of power sizing without a significant

margin (based on a calculation with a stabilised temperature).

4.1.2 Operating principle of the domestic hot water system

The domestic hot water heating circuit consists of a heat pump, a 3-way valve and a FLUROCYL hot water tank equipped with an electric heater.

4.1 System Standalone description

The Standalone system consists of the following components:

- A Glow-worm Envirosorb heat pump,

- A "Standalone" hydraulic module,

- A staged back-up electric heater of 6kW max (inside Standalone module).

-A buﬀ er tank,

- A Systempro control unit,

- A wireless outdoor sensor,

- A wireless or wired room thermostat.

4.1.1 Operating principle in heating

The heating appliance consists of a heat pump and a hydraulic module equipped with an electric heater. The heat emitters can also be low temperature (underﬂ oor heating, ...) or (radiators...). In order to always obtain the best comfort/economy trade-oﬀ , the module heat pump and/or electric heater supply 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.

In order to always obtain the best comfort/economy trade-oﬀ , the heat pump and/or the FLUROCYL tank electric heater provide the energy needed to maintain the stored water at the required temperature.

The lower part of the tank is heated 3 times a day by the heat pump. In order to provide maximum economy, the electric heater heats the top part of the tank just to provide the comfort desired by the user.

- Operation with 1 temperature sensor on the tank allows 1 ignition maximum every 8 hours if the hot water programme is not activated.

- Operation with 2 sensors on the tank allows more intelligent management. The heat pump starts as a priority each time the temperature in the tank is cold. The electric back-up is used to reach the desired setting if this setting is higher than 50°C.

The lower the hot water temperature setting, the more the heat pump will provide energy and, therefore, more economic operation.

We recommend that you set a hot water setting of 50°C and allow the longest possible tank reheating via the hot water programme (at least 2 hours per programme time slot).
