SimplyVAV Se c t i o n 6: A p p l i c at i o n d r awi n g s This section covers the drawings, materials, and instructions for specific VAV applications. Each SimplyVAV model is designed for a specific set of applications. The following topics are for control technicians and engineers that will plan for and install controllers for SimplyVAV applications.
Page 42: Cooling Or Heating Without Reheat
Section 6: Application drawings KMC Controls, Inc. Cooling or heating without reheat The BAC-8001 is configured for single-duct cooling VAV control without reheat. Connect the controller as shown in the illustration Cooling or heating application drawing on page A BAC-8005 or BAC-8205 may also be used for this application.
Page 43: Staged Reheat
SimplyVAV Section 6: Application drawings Staged reheat The staged reheat application is for BAC-8005 or BAC-8205 controllers. The controllers are configured to switch reheat units that are controlled with 24 volts AC. Reheat units with up to three stages of reheat can be controlled by these controllers. For one-stage, electric reheat or hot water reheat with an on/off valve, use only output terminal BO6.
Page 44: Modulating Reheat
Section 6: Application drawings KMC Controls, Inc. Modulating reheat The modulating reheat application is for a BAC-8005 or BAC-8205 controller. The modulating option for reheat can control either an electric reheat unit with an analog input or a modulating hot water valve. The analog reheat output at output terminal AO3 varies between 0 and 10 volts DC.
Page 45: Time Proportional Reheat
SimplyVAV Section 6: Application drawings Time proportional reheat The time proportional reheat application is for BAC-8005 or BAC-8205 controllers. This application is typically used in hydronic systems with a hot water reheat coil and a wax top control valve. The reheat output is a triac that can switch up to 1 ampere at 24 volts AC. For cooling and heating, a duct temperature sensor is required for Discharge Air Temperature limiting and automatic changeover.
Page 46: Floating Reheat
Section 6: Application drawings KMC Controls, Inc. Floating reheat The floating reheat application is for BAC-8005 or BAC-8205 controllers. Use this application in hydronic systems that are controlled by an actuator with tri-state inputs. The reheat outputs are triacs that can switch up to 1 ampere at 24 volts AC.
Page 47: Dual-Duct Application
SimplyVAV Section 6: Application drawings Dual-duct application The dual-duct application is for a BAC-8007 controller. 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 Submittal sheets for several variations of this application are available from the BAC-8000 series page at KMCControls.com.

Page 49: Section 7: Sequences Of Operation
SimplyVAV Se c t i o n 7: Se 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.
Page 50: Occupancy Sequence
Section 7: Sequences of operation KMC Controls, Inc. STE-6000 series discreet temperature sensors—There are three models of the STE-6000 series sensors compatible with the SimplyVAV controllers. If one of the three sensors is detected, the sensor's temperature is mapped to the Space Temperature Reference value object as the temperature input value.
Page 51: Unoccupied
SimplyVAV Section 7: Sequences of operation Controllers with a connected motion sensor change to Occupied upon the detection of primary airflow and motion in the space. The unit will remain in the OCCUPIED state as long as periodic motion is detected and primary airflow continues. If motion stops, the controller changes to STANDBY.
Page 52: Setpoint Limits
Section 7: Sequences of operation KMC Controls, Inc. Active setpoint—The active setpoint is the current setpoint. The active setpoint is determined by the following. If the space is occupied, the controller uses the occupied setpoint as the active setpoint. If an STE-6014 and STE-6017 is connected, the Active setpoint is set by the dial to be a few degrees above or below the Occupied setpoint.
Page 53: Airflow Setpoints Sequence
SimplyVAV Section 7: Sequences of operation The SimplyVAV controllers use up to three PID loops. The heating PID loop. The cooling PID loop. The discharge air temperature (DAT) loop. For SimplyVAV controllers, the output of either the cooling and heating PID loop is used to calculate the position of the damper.
Page 54: System Diagnostic Indicators
Section 7: Sequences of operation KMC Controls, Inc. enabled, the VAV terminal will be controlled by the DAT loop. The unit will also limit the Discharge Air Temperature to within 15° F of the Space Temp Reference. When there is a call for heat and the primary air is cool air, the reheat outputs are directly controlled by the DAT Loop and the DAT Setpoint reset based on the output of the Heating loop.
Page 55: Need Ahu (Bv1)
SimplyVAV Section 7: Sequences of operation NEED AHU (BV1) The Need AHU Start value object is set to TRUE (1) for any of the following conditions. The system mode is UNOCCUPIED and the Cooling loop or the Heating loop is greater than 100% for longer than 10 minutes.
Page 56: Fan Operation
Section 7: Sequences of operation KMC Controls, Inc. Fan operation The SimplyVAV controllers support both series and parallel fan powered VAV units. For either type of fan operation, the fan is controlled through the following terminals. A binary output triac controls a 24-volt fan starting circuit. See the topic...
Page 57: Reheat Sequence
SimplyVAV Section 7: Sequences of operation When the unit Occupancy state is UNOCCUPIED, the fan starts and runs at minimum speed only on a call for heating. The fan starts when the Heating loop is greater than 5% and stops when the Heating loop is less than 1%. Illustration 7–3 Parallel fan operation MAX FAN SPEED OCCUPIED...
Page 58: Modulating Reheat
Section 7: Sequences of operation KMC Controls, Inc. Modulating reheat If the controller is configured for modulating reheat, it controls an analog reheat unit with 0- 10 volts DC at the analog reheat output. On a call for reheat, the reheat output is modulated over the span of the Reheat loop.
Page 59: Time Proportioned Reheat
SimplyVAV Section 7: Sequences of operation Time proportioned reheat For controllers configured for time proportional reheat, the duty cycle of a binary triac output varies over a 10 second period. For example, if the Reheat loop is at 50%, the reheat output is ON for 5 seconds and OFF for 5 seconds.
Page 60: Balancing Airflow Sequence
Section 7: Sequences of operation KMC Controls, Inc. Balancing airflow sequence Balancing airflow is the process of calibrating the internal airflow sensor to a known standard. In the field, airflow is measured with an airflow hood or other measuring instrument and then compared to the airflow measurements from the sensor in the controller.
Page 61: Dual Duct
SimplyVAV Section 7: Sequences of operation Dual duct A dual duct installation consists of separate primary heating and cooling ducts, both with control dampers and airflow monitoring. For this type of installation a SimplyVAV BAC-8007 controls the cooling air (primary) damper and a TSP-8001 actuator controls the heating air (secondary) damper.
