Model 2000T: TemperatureDisplay and Command Module
The Model 2000T is an indoortemperature sensor, display and user interface. It allows occupants of atemperature-controlled environment to interact with the HVAC equipment via theLonWorks communication protocol. Occupants can view room temperature, currenttemperature setting, outside air temperature, equipment operating status, andequipment alarms. Using the Model 2000T, the occupant can change the HVACoperating mode, the occupancy mode, as well as the temperature setpoint. Formaximum compatibility the Model 2000T is implemented using the LonMark 8090profile for Space Comfort Control Command Module. The Model 2000T has uniquefeatures to allow more accurate reporting of room temperature to the HVACequipment. One, the on-board temperature sensor is located away from theelectronics in a separate compartment. This allows a more accurate measurementof air temperature. Two, a temperature averaging function allows up to fourtemperature sensors to be averaged before the room temperature is reported. Thisis important for large rooms, office buildings, or homes where the location of asingle thermostat does not provide a good representation of the averagetemperature. A feature of the Model 2000T allows the occupancy button to be usedas an on/off switch to control other network attached devices.
