For cooling and heating, a duct temperature sensor is required for Discharge Air Temperature limiting and automatic changeover.
SimplyVAV Section 6: Application drawings Dual-duct application This application is for a BAC-8007 controller. The controller is configured for dual-duct operation. Dual-duct VAV requires a TSP-8001 actuator to be used with the BC-8007 as shown in the illustration Dual-duct wiring diagram on page 50. Submittal sheets for several variations of this application are available from the Resources page at www.SimplyVAV.com.
SimplyVAV S e c t i o n 7: S e q u e n c e s o f o p e r at i o n Topics in this section cover the sequences of operation for the SimplyVAV controllers. These are advanced topics for control technicians and engineers. These sequences of operation are descriptions of each major component of the SimplyVAV programming. They are provided as an aid to understanding on how the controllers operate. This section covers the following sequences of operation.
Section 7: Sequences of operation KMC Controls, Inc. Input sources The SimplyVAV controllers require specific sensors to measure room temperature, airflow, and discharge air temperature. All sensors are automatically detected and the programming is automatically set up for the sensors.
SimplyVAV Section 7: Sequences of operation l Occupied on page 53 l Unoccupied l Standby Occupancy can also be commanded by another BACnet device or an operator workstation connected the building automation network. See the topic System integration and networking on page 63 for details. Automatic occupancy If Automatic Occupancy is enabled, the controller will automatically toggle between Unoccupied, Occupied, and Standby based on the presence of primary airflow and motion in the zone.
Section 7: Sequences of operation KMC Controls, Inc. l Active cooling l Active heating l Occupied cooling l Occupied heating l Unoccupied cooling l Unoccupied heating l Standby cooling l Standby heating Types of setpoints The SimplyVAV controllers may use any of the following setpoints based on a user entered setpoint or the state of occupancy and standby which is described in the topic Occupancy sequence on page 52. Active setpoint—The active setpoint is the current setpoint.
SimplyVAV Section 7: Sequences of operation 70° F. If the user lowers the Occupied Cooling setpoint to 71° F, the controller recalculates the Occupied Heating setpoint and changes it to 67° F. PID control loops A PID control loop calculates an error value from the difference between the measured room temperature and the active setpoint. The error value is expressed as a percentage and is typically used in a BAS controller to control the state of an output.
Section 7: Sequences of operation KMC Controls, Inc. Temperature is above the SAT Changeover Temp plus 2° Fahrenheit, the SAT Changeover Mode is set to HEAT. The default changeover temperature is 74° Fahrenheit. See the topic Discharge Air Temperature (DAT) limiting on page 56 and Input sources on page 52. Discharge Air Temperature (DAT) limiting A Discharge Air Temperature senor and DAT limiting is required to control VAV units with reheat.
SimplyVAV Section 7: Sequences of operation System diagnostic indicators The controller programming includes four system diagnostic indicators in the form of BACnet value objects. l NEED AHU (BV1) l NEED COLDER SUPPLY (BV2) l NEED MORE STATIC (BV3) l NEED HOTTER SUPPLY (BV7) These diagnostic indicators or flags are monitored by other BACnet devices, such as air handling units, connected to the same building automation system as the controller.
Section 7: Sequences of operation KMC Controls, Inc. Damper operation Damper movement is determined by comparing the actual airflow reading to the airflow setpoints. If the actual airflow is within 5% of the setpoint, no damper action is initiated. Once within the 5% deadband, the actual airflow must be outside a 7% deadband before damper position changes. To improve stability near setpoint, the damper motor is pulsed when the actual flow rate is within 15% of the requested flow rate.
SimplyVAV Section 7: Sequences of operation Parallel Fan If the controller is configured for a parallel fan, any time the Occupancy mode of the controller is set to either OCCUPIED or STANDBY and there is a call for heat, the fan runs continuously. The fan starts when the Heating loop is greater than 5% and stops when the Heating loop is less than 1%. When the unit Occupancy state is UNOCCUPIED, the fan starts and runs at minimum speed only on a call for heating.
Section 7: Sequences of operation KMC Controls, Inc. Reheat loop % Illustration 7–4 Modulating reheat operation 100 HTG % 10 0 HTG SPAN -2F Room temp increase HTG SP Staged reheat If the controller is configured for staged reheat, it can control up to three stages of reheat through binary triac outputs. The reheat outputs are commanded On when the Reheat loop rises above the ON threshold and OFF when the loop drops below the OFF threshold.
SimplyVAV Section 7: Sequences of operation Reheat loop % Illustration 7–5 Time proportional reheat operation 100 HTG % 10 0 HTG SPAN -2F Room temp increase HTG SP Floating reheat If the controller is configured for floating reheat, it controls two binary triac outputs to drive the inputs of a tri-state actuator connected to a valve. If the Reheat loop is less than 30%, the valve is driven closed. If the loop is greater than 70%, the valve is driven open.
Section 7: Sequences of operation KMC Controls, Inc. At the start of the sequence, the controller drives the damper open until the airflow reaches the highest value of either the cooling or heating maximum airflow setpoints. An airflow measurement is made with an airflow hood and the actual airflow value is entered into the controller. Once the actual airflow is entered, the controller drives the damper closed to the lower value of either the cooling or heating minimum airflow.
SimplyVAV S e c t i o n 8: S y s t e m i n t e gr at i o n an d n e t wo r k i n g Topics in this section cover integrating the controllers into a building automation network. These are advanced reference topics for control technicians and engineers. The controllers can be installed as standalone controllers or they can be connected to a BACnet MS/TP network.
Section 8: System integration and networking KMC Controls, Inc. Connections and wiring Use the following principles when connecting a controller to an MS/TP network: l l l Connect no more than 128 addressable BACnet devices to one MS/TP network. The devices can be any mix of controllers or routers. To prevent network traffic bottlenecks, limit the MS/TP network size to 60 controllers.
