Here in the figure above the three Temperature limit switches ( Temperature Limit 1, Temperature Limit 2 and Temperature
Limit 3) can provide various temperature ranges of operation by means of different combinations of dip switches as shown
in the Table below. These temperature limits prevent overcooling and over heating, by limiting the lowest temperature for
cooling and by limiting the highest temperature for heating respectively, thereby reducing energy costs.
