ABSTRACT:
A thermostat construction for controlling the output effect of a heat exchanger means, a system utilizing such a construction and a method of making such a construction are provided, the thermostat construction having a unit for sensing room temperature that is the result of the output effect, having a set-point unit for selecting a desired room temperature to be provided by the heat exchanger, having a changing unit for changing the effective set-point setting of the set-point unit to change the duty-cycle of the heat exchanger, and having a unit for sensing the current duty-cycle of the heat exchanger and for causing the changing unit to change the effective set-point setting to a different temperature setting thereof as the duty-cycle approaches a peak duty-cycle of the heat exchanger so that the current duty-cycles is reduced.
