Abstract

An apparatus and method for controlling the sequential operation of supplemental electric heaters so that the amount of energy consumption is minimized. The operation of the heaters is prevented as long as a lower night set-back temperature can reach the higher reference set point during the daytime within a predetermined time interval. A microprocessor is provided to control the operation of night set-back automatically to affect a measured temperature of the conditioned space.
