External Auxiliary Equipment; Aerothermal Or Hybrid Source Systems - GeoSmart NETZERO BW Manuel D'installation

Description
DG1 direct unit
SG2 unit with mixture
SG3 unit with mixture
SG4 unit with mixture
▪
Heat pump provides 24Vac connection from the electrical panel, remember that all the devices
connected to the heat pump cannot exceed 36VA or 1.5A. Exceed these limits could cause poor heat
NOTE
pump operation and/or heat pump component breakdowns.

5.9. External auxiliary equipment

This is used to control the activation of the auxiliary equipment integrated in the DHW heating buffer storage tanks via outputs to
relays. They are also used to control activation of the all / nothing external auxiliary boiler. If modulating boilers are installed, it is
also used to control the temperature downstream from the boiler, so the heat pump and the boiler can function simultaneously.
The connection terminals of the SG3 outlet unit are used to manage the auxiliary boilers, so this one cannot be used.

5.10. Aerothermal or hybrid source systems

These are used to control activation of the aerothermal (NETZERO AU12) and geothermal source systems. They also generate a
regulation signal for the variable speed fan of the NETZERO AU12 unit.
The connection terminals of the SG2 outlet unit are used to manage the aerothermal source units, so this one cannot be used.
