CTH - Ceiling Temperature and Humidity - High precision temperature and humidity sensor that is easily mounted on a ceiling by a threaded bush.
RTH - Remote Temperature and Humidity - High precision temperature and humidity sensor that is mounted on a wall.
DTH - Duct Temperature and Humidity - High precision temperature and humidity sensor that is easily mounted on an RTU duct.
LPI - Lighting Panel Interface - Adds physical control capabilities to the ITM for lighting. Interfaces with high power relays in a circuit panel.
HIA - HVAC Interface Adapter - Adds physical control capabilities to the ITM. Stripped out Smart Node architecture without a display, bluetooth or 900 Mhz comms.
ITM - Intelligent Temperature Mote - Room sensor and user interface. Measures temperature, humidity and light in a zone.
OAO - Outside Air Optimizer - Smart economizer controller for RTU.
IAQ - Indoor Air Quality - CO2 levels (others for mechanics)
DCV - Demand Controlled Ventilation - Optimizes the outside air damper position based on IAQ needs by sensing CO2 levels in the return air system.
DAB - Dynamic Airflow Balancing - Predictive algorithms model the thermal envelope of your building and send out the optimal strategy to achieve the perfect balance.
MAT - Mixed Air Temperature - Used to determine infiltration for accurate DCV and optimize “free” outside air.
OAD - Outside Air Damper - Admits fresh air into the system according to factors such as IAQ and energy savings.
WRM - Wall Room Module - Connects to the CCU allows attenuation and sensing of zone.
