摘要： The difference temperature TD between an actual temperature TA and a setpoint temperature TSP passes through PID (proportional, integral, and differential) circuitry 17 to give a target temperature TT. An error temperature TE is the difference between TT and a delivered water temperature TDW, and drives a flip-flop FF1 via a hysteresis circuit 21. FF1 produces a control signal for turning on a heat source HS, from which hot water is pumped to a radiator R. The heat source HS may be a heat pump, which draws a transient high inrush current when turned on. To minimize the inrush currents, a timer TMR is triggered by the control signal and prevents (by logic 22-24) the generation of a further control signal until the timer period has expired. The system may be implemented by a microprocessor.

摘要翻译： 实际温度TA和设定点温度TSP之间的差温度TD通过PID（比例，积分和差分）电路17以给出目标温度TT。 误差温度TE是TT与输送水温TDW之间的差值，并通过滞后电路21驱动触发器FF1.F1产生用于打开热源HS的控制信号，热源HS被泵送到 散热器R.热源HS可以是热泵，其在打开时吸收瞬时的高冲击电流。 为了最小化浪涌电流，定时器TMR1由控制信号触发，并且防止（通过逻辑22-24）生成另外的控制信号，直到定时器周期已经到期。 该系统可以由微处理器实现。
