CONFIGURATION B
Figure 4: Electrical diagram of configuration B. A PAST® storage tank is used; the heat sources primarily include an outdoor unit of a heat
pump with direct condensation in the tank and a bivalent gas boiler and also a solid fuel boiler without its own electronic control; the
heat consumers include flow heating of hot water in the tank, one heating circuit with classic radiators and one heating circuit for
heating the pool by means of a pool heat exchanger. The connection differs from configuration A only in replacing the electrical bivalent
system with a gas boiler. The switching of the gas boiler can always be done directly by means of a relay output of the controller
because this output is potential-free.
If the gas boiler manual prescribes a requirement for switching by a potential-free contact, only
relay output Re1 or Re2 can be used, the triac and external outputs cannot be used!
Figure 5: Simplified heating diagram of configuration B. The explanatory notes are identical with configuration A. Block O refers to the
gas boiler.
