Abstract

Abstract An apparatus for power load-shedding is disclosed which has an auxiliary thermostat disposed in the conditioned space for controlling the CN-OFF cycling function of a space conditioning apparatus during a load-shedding interval. The auxiliary thermostat includes an external communication signal receiver and a transmitter for transmitting control signals to a space conditioner control which controls the connection of available power to the space conditioner. The thermostat utilized during normal operation of the space conditioning means is disconnected during the load-shedding interval. The auxiliary thermostat is adapted to be supplied with line voltage as by plugging into a conventional outlet.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 135 words
An apparatus for controlling the operation of a thermostatically controlled space-conditioning means comprising: auxiliary thermostat means disposed in a conditioned space for controlling the ON-OFF cycling function of a space conditioning means during a load-shedding interval; space conditioning control means in communication with said auxiliary thermostat means for connecting and disconnecting power to said space conditioning means in response to communications from said auxiliary thermostat means; disconnect means connected to said space conditioning control means for disconnecting the thermostat utilized during normal operation of the space conditioning means for the interval of control by said auxiliary thermostat means; and communication means including transmitter means associated with said auxiliary thermostat means for sending control signals to said space conditioning control means and receiving means associated with said space conditioning control means for receiving said control signals.
Claim 2
Independent Claim 135 words
An apparatus for controlling the operation of a thermostatically controlled space-conditioning means comprising: auxiliary thermostat means disposed in a conditioned space for controlling the ON-OFF cycling function of a space conditioning means during a load-shedding interval; space conditioning control means in communication with said auxiliary thermostat means for connecting and disconnecting power to said space conditioning means in response to communications from said auxiliary thermostat means; disconnect means connected to said space conditioning control means for disconnecting the thermostat utilized during normal operation of the space conditioning means for the interval of control by said auxiliary thermostat means; and communication means including transmitter means associated with said auxiliary thermostat means for sending control signals to said space conditioning control means and receiving means associated with said space conditioning control means for receiving said control signals.
Claim 3
Dependent Claim 28 words
