|
|
Setpoint | Default | Valid range |
|
|
|
Occupied heating setpoint | 71°F | 40 to 115° F |
Occupied cooling setpoint | 74°F | 40 to 115° F |
Occupied standby heating setpoint | 67 °F | 40 to 115° F |
Occupied standby cooling setpoint | 78 °F | 40 to 115° F |
Unoccupied heating setpoint | 60°F | 40 to 115° F |
Unoccupied cooling setpoint | 85°F | 40 to 115° F |
Heating setpoint low limit1 | 40°F | 40 to 115° F |
Cooling setpoint low limit1 | 40°F | 40 to 115° F |
Heating setpoint high limit 1 | 105 °F | 40 to 115° F |
Cooling setpoint high limit 1 | 110 °F | 40 to 115° F |
Thumbwheel setpoint | Enable | Disable or enable |
|
|
|
1.The heating and cooling setpoint high and low limits only apply to the occupied and occupied standby setpoints and are never applied to the unoccupied setpoints.
Discharge Air Limits
Table 16: Discharge air limit ranges |
|
|
|
|
|
| Default | Valid range |
|
|
|
Low limit 1 | 38 °F | 30 to 50°F |
Control point high limit2 | 150 °F | 38 to 150°F |
Control point low limit2 | 45 °F | 35 to 150°F |
|
|
|
1.The low limit is the temperature at which the controller shuts down the unit to prevent the coil from freezing.
2.The control algorithm is limited to calculating this discharge air temperature based on capacity request.
Freeze Avoidance
Table 17: Freeze avoidance setpoint range |
|
|
|
|
|
| Default | Valid range |
|
|
|
Freeze avoidance setpoint1 | 40 °F | 20 to 60° F |
|
|
|
The controller disables freeze avoidance when the outdoor air temperature rises 3 °F above the freeze avoidance setpoint.
