    • The present invention relates to transforming a pre-existing heating installation comprising a main heat generator such as a boiler which is associated with a modulating mixer valve controlled by a P or PD type regulator which is responsive to outside temperature and to the departure temperature of the heating water. In accordance with the invention a control device is inserted between said pre-existing regulator and said pre-existing valve, said control device including an integrator module (110) connected to the output from said pre-existing regulator and controlling a threshold relay (120) which in turn provides successive on/off control of auxiliary heat generators such as heat pumps, when respective thresholds are detected, said control device further including a switch (170, 171, 161) controlled by the threshold relay in the event that heat demand exceeds the supply available from the auxiliary generators in order to allow the signals from the conventional regulator (6, 7) to be applied to the mixing valve in order to enable the main heat generator to be switched on.
    • 本发明涉及转换预先存在的加热装置,其包括主要发热体,例如锅炉,其与由P或PD型调节器控制的调节混合器阀相关联,该调节混合器阀响应于外部温度和出口温度 加热水。 根据本发明,控制装置插入在所述预先存在的调节器和所述预先存在的阀之间,所述控制装置包括与所述预先存在的调节器的输出端相连并控制阈值继电器的积分器模块(110) ),其进而依次提供诸如热泵的辅助热发生器的连续的接通/断开控制,当检测到相应的阈值时,所述控制装置还包括由阈值继电器控制的开关(170,171,161) 超过了从辅助发电机供应的供应,以便允许来自常规调节器(6,7)的信号施加到混合阀,以使主热发电机能够接通。
