Description |
Default Value |
---|---|---|---|
CDTHI-SP, DATHI-SP, or HDTHI-SP (Discharge Air High Setpoint) |
Defines the Discharge Air Setpoint when the OA Temperature input equals the OA Reset B value. |
Depends on use (°C, °F) |
|
CDTLO-SP, DATLO-SP, or HDTLO-SP (Discharge Air Low Setpoint) |
Defines the Discharge Air Setpoint when the OA Temperature input equals the OA Reset A value. |
Depends on use (°C, °F) |
|
CDT-OARSTA, DAT-OARSTA, HDT-EARSTA, HDT-OARSTA, or HDT-RARSTA (OA Reset A) |
Specifies that when OA Temperature equals this value, the Discharge Air Setpoint equals the Discharge Air Low Setpoint. |
Depends on use (°C, °F) |
|
CDT-OARSTB, DAT-OARSTB, HDT-EARSTB, HDT-OARSTB, or HDT-RARSTB (OA Reset B) |
Specifies that when the OA Temperature equals this value, the Discharge Air Setpoint equals the Discharge Air High Setpoint. |
Depends on use (°C, °F) |
|
CDT-SP or HDT-SP (Discharge Air Setpoint) |
G, V |
Discharge Air Setpoint as determined by this module based on the OA Temperature level. |
Depends on use (°C, °F) |
