The MS/TP Microset II utilizes the BACnet MS/TP network layer. This new sensor is perfect for split zone VAVs, multi-zone rooftop units, or any VLX, VLCA-1688, or VLC-16160 application where more than one room sensor with display is needed to meet the application, but the MS/TP Microset II can control multiple zones.
Features:
- Versatile
Occupant can view room and outside air temperatures, select fan speed and change room temperature setpoints. Data and functions are configurable.
- Energy Efficient
Occupants can select after-hours operation in 30-minute increments or turn zone equipment ON and OFF.
- Flexible
A programmable field service mode allows maintenance personnel to monitor and adjust control parameters from the MS/TP Microset II’s™ field service mode.
- Points
Points can be used in peer-to-peer applications. - Interoperable
BACnet-compliant on MS/TP LAN at up to 76.8 Kbps.
- Attractive
Modern styling enhances any interior, and functional design makes operation intuitive.

- Flexible
A programmable field service mode allows maintenance personnel to monitor and adjust control parameters in the VLC from the Microset’s field service mode.
- Attractive
Modern styling enhances any interior, and functional design makes operation intuitive.
Microtouch (BACtalk)
Alerton BACtalk temperature sensors are high-resolution temperature sensors that utilize the same industrial-grade sensing element. The element is precalibrated and requires no field calibration. MICROTOUCH is an aesthetically pleasing sensor that senses temperature, allows tenant override and setpoint adjustment.
Features:
- Reliable
An interchangeable, industrial-grade thermistor provides consistent accuracy and interfaces with Alerton® field equipment.
- Flexible
Use the Microset™ Service Tool at the BACtalk® Microtouch™ to adjust setpoint ranges, afterhours override time, VAV box CFM setpoints, heat pump economizer setpoints, and more.
- Energy-efficient
Maintenance and energy costs are reduced with operator-established after-hours override time and temperature bias setpoints.
- Attractive
Discreet and stylish, the BACtalk Microtouch is the ideal companion to any building’s interior decor.
