The following table describes the attributes used by the Occupied Zone Sequencing (HP) module.
|
Name |
Description |
Default Value |
|---|---|---|
|
Cooling Control Status |
Contains the value fed back from the cooling controller necessary for the sequencer to determine what actions to take. |
Overridden Set Name: Control Status |
|
Cooling Setpoint |
Contains the desired zone temperature when under cooling control. |
23 °C, 74 °F |
|
Damper Control Status |
Value fed back from the damper controller necessary for the sequencer to determine what actions to take. |
Overridden Set Name: Control Status |
|
Discharge Air Temperature |
Contains the value that is to be compared to the Discharge Air Low Limit (DALL) and is used to determine whether it is necessary to enter DALL control to modulate the OA Damper closed to keep the discharge air temperature from falling below the DALL. |
22 °C, 72 °F |
|
Fast Sequence Enabled |
Allows the user to enable or disable the transition to satisfied when the setpoint changes by more than the Setpoint Threshold. |
True |
|
Free Cooling Available |
Indicates whether economizer cooling is available. |
False |
|
Heating Control Status |
Value fed back from the heating controller necessary for the sequencer to determine what actions to take. |
Overridden Set Name: Control Status |
|
Heating Percent Cmd |
Indicates the current command from the heating controller that operates first. This signal comes directly from the PID in the output controller module. |
0.0 Display Units: % |
|
Heating Setpoint |
Contains the desired zone temperature when under heating control. |
21 °C, 70 °F |
|
Low Limit Setpoint |
Contains the low limit for the Discharge Air Temperature. |
13 °C, 55 °F |
|
Occupancy |
Accepts the current occupancy status. |
Occupied Set Name: Occ Effective |
|
Setpoint Threshold |
Contains the value used to determine whether a significant setpoint change has occurred. |
1 °C, 2 °F |
|
Supp Heating Control Status |
Contains the value fed back from the supplemental heating controller necessary for the sequencer to determine what actions to take. |
Overridden Set Name: Control Status |
|
ZNT-STATE (State) |
Represents the current state generated by the heat pump zone temperature sequence. |
Satisfied |
|
Zone Temperature |
Contains the measured temperature in the zone. |
22 °C, 72 °F |
