KMC Controls SimplyVAV BAC-8001 User Manual

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.
l For one-stage, electric reheat or hot water reheat with an on/off valve, use only output
terminal BO6.
l For two-stage reheat use output terminals BO6 and BO7.
l For three-stage reheat use output terminals BO6, BO7, and BO8.
For cooling and heating, a duct temperature sensor is required for Discharge Air Temperature
limiting and automatic changeover. See the topic Advanced options on page 33 for
instructions to enable Discharge Air Temperature limiting.
When connecting the controller to a fan powered VAV unit, the fan circuits must be
compatible with the following specifications.
l The fan start circuit is a 24 volt AC pilot duty output.
l The fan speed output is 0-10 volts DC.
Submittal sheets for several variations of this application are available from the BAC-8000
series page at KMCControls.com.
