1. A line voltage adapter and programmable thermostat comprising:

  • (a) parallel resistive and capacitive means effectively and directly connected with a voltage source above about 110 VAC for receiving, reducing and outputting line voltage to that required by the programmable thermostat, the reduction comprising reducing an input voltage from about 110 VAC to 330 VAC to an output voltage substantially below 110 VAC from the parallel resistive and capacitive means; and

    (b) a programmable thermostat effectively and directly connected to receive the output voltage, where the programmable thermostat comprises circuit elements whose operation is substantially adversely affected unless an applied voltage is substantially less than about 110 VAC.
