SMT-ASCVT

The SMT-ASCVT is a multi-functional air volume (VAV) and constant air volume terminal box controller with 5 binary Triac Outputs designed to provide standard and advanced VAV control routines. This high-speed BACnet MS/TP direct digital controller is BTL listed as a BACnet Application Specific Controller (B-ASC) that supports all standard BACnet baud rates.

 

SMT-ASCVT Features

Software Configurable Device Addressing - for BACnet MS/TP network protocol
Dedicated Zone Temperature Input - utilizing STATbus protocol with the ability to network up to four (4) digital SBC-STAT devices
Two (2) Universal Inputs - configurable for discharge temperature, outside air temperature, occupancy detection, proof of flow sensing, and other general purpose input sensing applications. The Universal Inputs arejumper selectable to allow for configuration of resistance, DC voltage, or current signal types
Five (5) Binary Triac Outputs - can control a series or parallel fan, control up to four (4) stages of electric reheat, or manipulate an auxillary valve for heating and cooling changeover. All outputs include run hour tracking
One (1) Analog Output - used for auxiliary PID control of proportional valves, or other application with a host device
One (1) Standard PID Control Loop - fully configurable for analog output applications.
Support for One (1) BACnet Schedule - provides complete time of day scheduling (a BACnet Time Synchronization message must be received periodically)
Configurable Setpoint - with optional setback for unoccupied and night setback modes.
Onboard Occupancy Detection - allows the device to switch to occupied mode based on a signal from an occupancy sensor connected to an available input
