Siemens BACnet Heat Pump Controller -
Description | Address | Application | Description |
|
|
|
|
SWITCH DBAND | 90 | 2583, 2584 | Temperature range in degrees that is compared to the |
|
|
| difference between CTL TEMP and CTL STPT. The |
|
|
| difference must exceed this value for temperature control |
|
|
| mode to change over. Changeover is also subject to the |
|
|
| active temperature control loop output being below SWITCH |
|
|
| LIMIT and SWITCH TIME being expired. |
|
|
|
|
NGT MA CTL | {91} | 2583, 2584 | YES indicates that mixed air control should occur during |
|
|
| night mode. NO indicates that mixed air control will not |
|
|
| occur during night mode. |
|
|
| Valid input: YES or NO. |
|
|
|
|
CTL STPT | {92} | 2583, 2584 | Actual setpoint value being used as input for the active |
|
|
| temperature control loop. |
MA STPT | {93} | 2583, 2584 | Setpoint of the mixed air control loop. |
|
|
|
|
EHEAT 2 ON | 94 | 2583 | Value, in percent, that the heating loopout must exceed for |
|
|
| the second stage of electric heat to turn ON. |
|
|
|
|
EHEAT 3 ON | 95 | 2583 | Value, in percent, that the heating loopout must exceed for |
|
|
| the third stage of electric heat to turn ON. |
|
|
|
|
CAL TIMER | 96 | 2583, 2584, 2590 | Time interval, in hours, between the calibration sequence. |
|
|
|
|
AOV 3 | {97} | 2583, 2584, 2590 | Analog output 3 controls a 0 to 10V signal. |
|
|
|
|
LOOP TIME | 98 | 2583, 2584 | Time, in seconds, between control loop calculations. |
|
|
|
|
ERROR STATUS | {99} | 2583, 2584, 2590 | Status code indicating any errors detected during controller |
|
|
| power up. A status of 0 indicates there are no problems. |
CLG D GAIN | 102 | 2583, 2584 | Derivative gain value for the cooling temperature control |
|
|
| loop. |
|
|
|
|
CLG BIAS | 103 | 2583, 2584 | Biasing of the cooling temperature control loop. |
|
|
| See CLG LOOPOUT. |
|
|
|
|
HTG D GAIN | 104 | 2583, 2584 | Derivative gain value for the heating temperature control |
|
|
| loop. |
HTG BIAS | 105 | 2583, 2584 | Biasing of the heating temperature control loop. |
|
|
| See HTG LOOPOUT. |
