Notes
|
OCC
|
Indicates whether or not the zone is currently occupied.
|
FOR
|
Indicates how long the zone will remain in its current state of occupancy.
|
ZONE
|
Current zone temperature.
|
HTSP CLSP
|
Heating (or cooling) setpoint in degrees.
|
CLG%
|
The cooling requirement in percent.
Use this signal to control the cooling system through an output microblock, such as the Airflow Control microblock.
This output can also be used to trigger "I need cool" requests back to the air handler unit.
|
HTG%
|
The heating requirement in percent.
Use this signal to control the heating system through an output microblock, such as the Airflow Control microblock.
This output can also be used to trigger ģI need heatī requests back to the air handler unit.
|
Cooling Loop Gain
|
An adjustment to the speed of the integral action relative to the proportional action when the system is in a cooling mode. If the system begins cycling, decrease this setting.
Range: 1 to 5
Default: 5

Maintain Setpoint ±
|
Controls how far from the heating or cooling setpoint the system can vary before the controller calls for full heating or cooling. The controller calls for full heating or cooling when the temperature comes within 75% of this limit; this helps ensure the limit is not exceeded. If a zone has a cooling setpoint of 74 Deg F, for example, and cannot be allowed to rise above 75 Deg F under any circumstances, a setting of Maintain Setpoint +/-1 Deg F calls for full cooling if the temperature rises to 74.75 Deg F. Similarly, if the heating setpoint is set at 70 Deg F, the controller calls for full heat if the temperature drops below 69.25 Deg F. The default setting maintains excellent control in most situations, but can be increased if the system begins to cycle.Range: 1 to 5Default: 1
|
RefName
|
Use the default reference name unless you want a more descriptive name for this microblock for graphics, source tree rules, or network links. All reference names in a control program must be unique.
|
Property Page Text
|
Enter a meaningful description of the microblock for use on the Properties page in WebCTRL.
|
Editing Privilege
|
Preset (the default Editing Privilege) indicates that each property in a microblock has an appropriate privilege assigned to it.
If you change the Editing Privilege, all the properties in that microblock are assigned to that one editing privilege, which is not always desirable.
