ABSTRACT:
To be used with a pool assembly of the type including a swimming pool, and a pool pump, a self regulating pool heater unit having a refrigeration unit structured and disposed to emit heat in order to heat a quantity of water cycled therethrough by the pool pump. Further, a power source is included and connected to the refrigeration unit, and to the pool pump through a timer. The timer has an on mode which sets a predetermined time period during which the power supplied by the power source flows therethrough to the pool pump so that it will function, and an off mode wherein no power flows through the timer to the pool pump. Additionally, an automatic timer bypass is included and connected in line between the power source and the pool pump. The automatic timer bypass is switchable between a bypass position and a normal position, the bypass position being defined by power flowing through the automatic timer bypass so as to bypass the timer, if it is not in the on mode, thereby ensuring that power flows to the pool pump regardless of the mode of the timer. Conversely, the normal position of the automatic timer bypass allows power to flow to the pump only through the timer. Further, the unit is structured to indicate when any of a number of defined hazardous operating conditions are present and prevent operation if the refrigeration unit.
