Setpoints heading the operator is able to display/modify the current value of the points listed in the Temp Setpoints table
shown below, see Table 5.
This table shows that an operator must be logged on as a level 2 operator in order to modify the setpoint values. If the
operator has logged onto a level less than level 2, then the screen displays only the data and engineering units for that point
as shown in the previous screen view for the Room Temp .

0 through 10 ° F (-17.8 through -12.2 ° C)
The HHT enforces the following relationships (when the Enter key is pressed):
 Setpoint Value range of 40 to 90 ° F (4 to 32 ° C)
 Heating Unoccupied < Heating Standby
 Heating Standby < Heating Occupied
 Heating Occupied < Cooling Occupied
 Cooling Occupied < Cooling Standby
 Cooling Standby < Cooling Unoccupied
