1. A wireless thermostat system for an electric heater, comprising:

  • a thermostat having a first temperature sensor;

    an equipment interface module (EIM) separate from the thermostat and wirelessly connected to the thermostat, the EIM comprising;

    an antenna sub-system; and

    a relay sub-system connected to the antenna sub-system; and

    wherein;

    the thermostat comprises a wireless transmitter;

    the antenna sub-system comprises;

    an antenna for detecting signals from the wireless transmitter; and

    a first electronic circuit having a second temperature sensor and an input connected to the antenna;

    the relay sub-system comprises;

    a second electronic circuit having an input connected to an output of the first electronic circuit; and

    a relay with an input connected to an output of the second electronic circuit, and having an output for connecting power to an input of an electric heater;

    the EIM is configured to control the electric heater in response to control signals received from the thermostat, the control signals being based on temperature sensed with the first temperature sensor; and

    the EIM is configured to control the electric heater independent of the thermostat when the second temperature sensor senses a temperature below a predetermined temperature.
