ABSTRACT:
A heating system control device is responsive to the drop in outside temperature to below a predetermined weatherhead set point for turning on a heating system to be controlled. Upon the establishment of the heat in the heating system, a defined heating cycle is carried out consisting of a heat-on portion and a heat-off portion having a duty cycle dependent on the outside temperature. The heating cycle does not start until there is an establishment of heat in the heating system. The start of consecutive heating cycles is delayed in response to a check for heat loss in the system. When heat is established and the set point has not been reached, as noted by the means for determining the establishment of heat in the heating system, the next cycle will be delayed to save energy.
