The new Sears solid state programmable thermostat indeed looks at the rate of change in the room temperature to help maintain a setpoint. It therefore is capable of holding the house temperature quite steady. This could potentially cause problems on the air-conditioning mode, since the compressor of a house airconditioner should not cycle too often (most of them have a built in delay relay). In the airconditioning mode the thermostat has a programmed in delay of 4 min. It is also possible to get osciillation in the heating mode. If this happens the user can program in a delay there as well. The time program allows for four temperature changes per day, on a 2 and 5 day series basis (weekday and weekend). There is also an override for the current time period and for all time periods. A nice package, especially when on sale in the mail order flyer at $ 70.0 Herman Silbiger AT&T-IS Lincroft
