KMC Controls BAC-4201CW0003 BACnet or Stand Alone Thermostat Product Specifications Guide

KMC Controls BAC-4201CW0003 BACnet or Stand Alone Thermostat

Description

The KMC AppStat combines the power of a space‑mounted equipment controller with the convenience of built‑in temperature, humidity and motion sensors. The controllers include a wide range of factory supplied programs for the following applications.

• Two and four pipe fan coil units
• Roof top units
• Heat pump units
• Packaged and split unitary systems

Stand alone operation
No special programming, software applications, or setup tools are required to configure and commission an AppStat. All options can be set by using only the five front panel buttons and the easy‑to‑read menus in the full color display.

New or retrofit applications
The attractive two‑piece design is ideal for new installations or upgrades of older, less efficient thermostats. AppStat installation requires only mounting the backplate to a wall or electrical box, connecting wires to screw terminals, and plugging the AppStat into the backplate.

Bright, full-color display
The full color display is easy to read across a room even in bright sunlight. Users can easily choose between Fahrenheit or Celsius values. The display features large numbers and simple color icons to indicate heating or cooling, occupied, unoccupied or local setback modes, and fan operation. For models with a humidity sensor, the temperature and humidity values alternate on the display.

Network ready
All models are native BACnet, Application Specific Controllers ready to connect to a BACnet MS/TP network. Device instance, MAC address, and baud rate are set from the password protected front controls. All models feature a hardware clock and BACnet schedule that can be set up from the front panel or as standard BACnet objects and properties.

Specifications

Full color user interface
