This application is for BAC 8005-36 controller. The controller 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 or electric reheat or hot water reheat with an on/off valve, use only output terminal BO6.
• For two-stage reheat use output terminals BO6 and BO7.
• For three-stage reheat use output terminals BO6, BO7 and BO8.
For cooling and heating, a duct temperature sensor is required for automatic changeover.
When connecting the controller to a fan powered VAV terminal unit, the fan circuits must be compatible with the following
specifications.
• The fan start circuit is a 24 volt AC pilot duty output.
• The fan speed output is 0 – 10 volts DC.
