Abstract

A control method uses a room thermostat for generating an output signal representative of an energy demand and an energy source which can be cyclically switched on and off and includes the steps of determining within a switching cycle of the energy source the actual switch on period, comparing the actual switch on period with an adjustable desired switch on period within the cycle to produce a control signal representative of the energy demand and controlling the energy source in accordance with the control signal. An apparatus utilizing this method uses a first adjustable timer for setting a cycling time period, a second adjustable timer for setting a desired switch on period within each cycling period, a time measuring unit for measuring the actual switch on time of an energy source in response to a room thermostat establishing an energy demand, a comparator for comparing the actual switch on time with the desired switch on period to produce a representative control signal and a control element responsive to the control signal for correspondingly changing the rate of energy supplied by the energy source.
