Central heating with boiler and heat pump - has regulator with ambient air temp. sensors and changeover switch

摘要

The hot water heated central heating system has two heat generators, especially a heat pump and a boiler. The regulating system includes single regulator (10) used for both heat generators (1, 3). This regulator has changeover switch system (11) for connecting regulator to both heat generators (1, 3). This changeover switch is actuated by an ambient temp. sensor (14) ensuring actuation at a specified temp., for example at plus three degrees. The ambient air temp. sensor (14) of the changeover switch (11) is arranged into a common sensor housing (15) together with another ambient temp. sensor acting on regulator (10).
