Siemens BACnet Heat Pump Controller -
Description | Address | Application | Description |
|
|
|
|
Dl OVRD SW | {19} | 2583, 2584, 2590 | Actual indication of the status of the override switch (not |
|
|
| physically available on all temperature sensor models) at the |
|
|
| room temperature sensor. ON indicates that the switch is |
|
|
| being pressed. OFF indicates that the switch is released. |
|
|
| Valid input: ON or OFF |
OVRD TIME | 20 | 2583, 2584 | Amount of time in hours that the controller will operate in |
|
|
| day/occupied mode when the override switch is pressed |
|
|
| while the controller is in night/ unoccupied mode. |
|
|
|
|
NGT OVRD | {21} | 2583, 2584 | Indicates the mode that the controller is operating in with |
|
|
| respect to the override switch. NIGHT indicates that the |
|
|
| switch has not been pressed and the override timer is not |
|
|
| active. DAY indicates that the switch has been pressed and |
|
|
| the override timer is active. The controller then uses a day |
|
|
| mode temperature setpoint. This point is only in effect when |
|
|
| DAY.NGT indicates night mode. |
|
|
|
|
RMTMP OFFSET | 22 | All | Compensates for deviations between the value of ROOM |
|
|
| TEMP and the actual room temperature. This corrected |
|
|
| value is displayed in CTL TEMP. |
|
|
| RMTMP OFFSET + ROOM TEMP = CTL TEMP |
FREE CLG | {23} | 2583, 2584 | Point commanded by the field panel PPCL to enable or |
|
|
| disable mixed air control (free cooling). |
|
|
|
|
DI 2 | {24} | 2583, 2584, 2590 | Actual status of a contact connected to the controller at Dl 2. |
|
|
| ON indicates that the contact is closed; OFF indicates that |
|
|
| the contact is open. If a wall switch is used, it is connected |
|
|
| to DI 2. See WALL SWITCH. |
|
|
|
|
DI 5 | {25} | 2583, 2584, 2590 | Actual status of a contact connected to the controller at |
|
|
| Al 5/Dl 5. ON indicates that the contact is closed; OFF |
|
|
| indicates that the contact is open. When a contact is |
|
|
| connected at Dl 5, Al 5 is not available. See Point number |
|
|
| 15. The physical input can not be used for both analog and |
|
|
| digital input at the same time. |
|
|
|
|
DI 6 | {26} | 2583, 2584, 2590 | Actual status of a contact connected to the controller. ON |
|
|
| indicates that the contact is closed; OFF indicates that the |
|
|
| contact is open. Application 2583/2584: DI 6 can be used to |
|
|
| monitor an input that changes state when the heat pump is |
|
|
| in alarm. DI 6 can be unbundled to send alarm information |
|
|
| to the field panel for centralized alarm monitoring. |

CMP2 MlN OFF | 27 | 2583 | Minimum time, in minutes, that compressor 2 will remain |
|
|
| OFF before turning ON. |
HTG2 MlN OFF | 27 | 2584 | Minimum time, in minutes, that heating compressor 2 will |
|
|
| remain OFF before turning ON. |

CMP2 MlN ON | 28 | 2583 | Minimum time, in minutes, that compressor 2 will remain ON |
|
|
| before turning OFF. |
HTG2 MlN ON | 28 | 2584 | Minimum time, in minutes, that heating compressor 2 will |
|
|
| remain ON before turning OFF. |
