## Control microblocks Control microblocks output signals that are used for control and scheduling purposes. Many of these microblocks generate colors, which are used to communicate control program or zone color status. NOTE Make sure a control program broadcasts a single color by using one of the following: 1 Setpoint microblock 1 Set Color microblock 1 or more Set Color If True microblocks
| BACnet Setpoint This microblock compares the zone temperature to the zone's effective setpoint to determine the zone color that represents the control program status. Other microblocks (such as the If Color = microblock) can use this color to perform additional control.
| Setpoint Optimization Optimizes a single setpoint to use the least amount of energy necessary to meet the needs of the controlled equipment.
| Set Color This microblock defines a color (white, gray, or red) for a control program that does not use a Zone Setpoint or Set Color If True microblock. This microblock is used so the control program displays a color in the WebCTRL® or Field Assistant system indicating its status.
| Set Color If True This microblock broadcasts the selected color for the control program when it is activated.
| True if Color = This microblock allows you to define control sequences based on the control program's current color.
| BACnet Time Clock with TLO and Override Status This microblock reads schedules from the WebCTRL® or Field Assistant system and generates signals to tell the control program whether or not the zone is occupied and how long the zone will remain in its current state.
| BACnet Multi-State Time Clock This microblock reads schedules from the WebCTRL® or Field Assistant system and generates values to tell the control program what state the zone is in, and how long the zone will remain in its current state.
