Room temperature is controlled to stay w ith in th e set temperature range th at
is specified for the Setback mode. By leaving sufficient temperature differential
betw een th e set temperature for cooling (upper limit) and h eating (low er limit) ,
it is possible to keep the room temperature ithin the specified range ithout
