This energy saving feature is based on the principal that long compressor run times lower indoor humidity and make a slightly higher temperature feel comfortable. Cool Savings operates only when the compressor runs 20 minutes or longer, normally on the hottest summer days. When Cool Savings is operating the thermostat will flash "Cool Savings" to indicate it is slowly adjusting the display temperature lower.
21.Compressor Optimization – (Not available on earlier models) CO provides a delay in circulator fan operation after the compressor turns on or off. With CO selected ON, when the compressor turns on (for a call for heat in heat pump or a call for cool) the fan will be delayed for five seconds before turning on to allow the air to be heated or cooled. After the compressor turns off for call for cool, the fan will continue to run for 20 seconds to capture additional cooling from the system. If CO is set to OFF, there will be no delay in fan operation.
