An apparatus for, and a method of, reducing cycling of heating and cooling systems by varying the deadband of a thermostat. The deadband is varied such that it does not impact human comfort significantly. The deadband is kept narrow (at its current normal value) during peak heating/cooling period, while it is made wider during periods of non-occupancy, shoulder months with low heating/cooling requirements, and set-back periods. The variation of deadband can be based on an internal clock/calender, an outdoor temperature sensor or a combination of both. The apparatus may be an electronic thermostat which may be programmable.
