features of the SBH. You can control all the outputs on the VAC1002 with the interlock feature or
with the scheduling feature on the SBH. You can also use the data share feature to share data from
one input source to multiple destinations.
Controller features
• Integrate facility loads, such as lighting or exhaust fans, into building occupancy schedules
• Circuitry and connectors for the five analog inputs, four binary inputs, nine binary outputs, five
wired or wireless NS sensors, and four energy meters
• Point interlocking for advanced control of multiple conditions, such as temperature, humidity,

, fan status, occupancy status, and control mode
• Customizable alarming for monitoring devices, conditions, or spaces
• Power monitoring to help you understand power usage in a facility
Constant Volume application
The Constant Volume application is a Verasys application. You can load the application to a
VAC1000 or VAC3000 depending on the equipment that you want to control. The Constant Volume
application adds to the features present in Smart equipment and extends the capabilities of the
TEC3xxx series for third-party equipment. The application includes support for up to four stages
of cooling and four stages of heating, modulated 0 V to 10 V output for heating and cooling, and
heat pump with an additional two stages of supplemental heat available. The Constant Volume
application can control a mixed air damper or set a minimum outside air damper position, and
meet Title 24 compliance for the state of California. Other supported features include occupancy
scheduling, outdoor air lockouts, dehumidification, humidification, demand control ventilation, and
much more.
Sideloop application
The Sideloop application is a Verasys application. You can load the application to a VAC1000.
You can use the Verasys Sideloop application to design simple loops that control various types of
equipment. Define the inputs, outputs, and netsensors, and enable and configure the control loops
that you want to use.
You can use analog and binary control loops, and a multistage control (MSC) loop. The available
control loop strategies include reset span, PID control with or without setpoint reset, binary to
analog, analog to binary, and binary interlock.
Verasys Zone Coordinator
The Verasys Zone Coordinator is used for multi-zone applications as an engine to coordinate a
complete VAV or COBP system. You can order an individual Verasys Zone Coordinator or a panel
version. The Verasys Zone Coordinator automatically recognizes the unit configuration, and
switches to either VAV or COBP based on the system type.
TEC30xx or TEC36xx Thermostat controllers
The TEC30xx and TEC36xx Series Thermostat controllers are Verasys Pro Wireless or BACnet MS/TP
thermostats that provide on and off, floating, and proportional control of the following elements:
• Local hydronic reheat valves
• Pressure-dependent VAV equipment with or without local reheat
• Two-pipe or four-pipe fan coils
