## Input and Output Points microblocks Input and Output Points microblocks communicate values between a control program and a controller's physical inputs and outputs. Input values are read from sensors connected to the controller's physical inputs. Output values are sent from the controller's physical outputs to control components on the controlled equipment. The Airflow and Zone Sensor microblocks belong to this family. Inputs
| BACnet Analog Input Reads the analog (continuous) value of a physical input on the controller. Converts the raw data from the sensor to the appropriate range for its unit of measurement (such as mA, degrees Fahrenheit, or psi).
| BACnet Binary Input Reads the binary (on or off) value of a physical input on the controller.
| Timed Local Override Reads a local override input signal from a user-adjustable switch or button in the zone. Converts the signal, then outputs a remaining time value.
| Pulse to Analog Input Counts pulses from a binary (on or off) input over a specified period of time. Every minute, calculates and outputs the average number of pulses received over the specified time.
Outputs
| BACnet Analog Output Sends an analog (continuous) value from the control program to a physical analog output on the controller.
| BACnet Binary Output Sends a binary (on or off) value from the control program to a physical digital (on or off) output on the controller.
| Floating Motor Works with a bi-directional motor actuator triggered by two digital signals, such as clockwise and counterclockwise or damper open and damper closed. Converts a percent open value from the control program to on and off signals to two physical digital outputs on the controller.
| Pulse-Width Output Converts a percent value from the control program to a digital on or off signal that varies in duration based on minimum and maximum values you define.
Zone (Airflow and Sensors)
| U Line Airflow Control Maintains VAV zone airflow at setpoint. Its inputs, outputs, and properties interface with the airflow control algorithm built into U line controllers. Enables VAV box testing and balancing through a LogiStat sensor.
| LogiStat Zone Sensor Sends information to and receives values from a LogiStat sensor. Works with a schedule and setpoint microblock to maintain zone temperature at setpoint.
| RS Zone Sensor Sends information to and receives values from a variety of sensor configurations. Works with a schedule and setpoint microblock to maintain zone temperature at setpoint.
| RS Zone Sensor with Fan Control Sends information to and receives values from a variety of sensor configurations. Works with a schedule and setpoint microblock to maintain zone temperature at setpoint. Enables the sensor's fan control and mode functionality.
| Airflow Control Maintains VAV zone airflow at setpoint. Its inputs, outputs, and properties interface with a controller's built-in airflow control algorithm. The algorithm ensures that zone airflow stays above the specified minimum for zone indoor air quality standards. Enables VAV testing and balancing through your system interface or through the stand-alone Airflow Test and Balance Utility.
| BACnet Pressure Dependent Control Calculates and maintains the desired damper position in a pressure dependent zone. Controls AUX reheat operation and fan operation in a fan powered box. Its inputs, outputs, and properties interface with the control algorithms built into other controllers. The algorithm ensures that zone airflow stays above the specified minimum for zone indoor air quality standards. Enables testing and balancing through the WebCTRL® interface or through a stand-alone utility. Controls the damper and other key zone operations, such as the fan (FAN) and auxiliary heat (AUX HEAT), during commissioning.
| BACnet Bypass Control Controls the bypass damper based on the commanded position input wire. Converts the pressure sensor count to pressure and output this value to the DUCT SP wire. Allows for the configuration of the duct static pressure setpoint and the maximum static pressure setpoint during LAT override. Enables testing and balancing through the WebCTRL® interface. Calibrates the airflow sensor readings at design setpoint and zero calibration of sensor when AHU fan is off. Calibrates full open and closed damper positions.
