Honeywell TB7300 Communicating Fan Coil Thermostat. More...

Detailed Description

This module implements support for the Honeywell TB7300 Communicating Fan Coil Thermostat. It may also support the TB7200, though only the TB7300 was available for development of this driver.

The TB7200 Series PI thermostats are designed for zoning applications, and the TB7300 Series PI thermostats are designed for fan coil control. Both Series are communicating thermostats with models available in BACnet(r) MS/TP protocol and can be easily integrated into a WEBs-AX building automation system based on the NiagaraAX(r) platform.

TB7200 and TB7300 Series thermostats are compatible with the Honeywell Occupancy Sensor Cover. Thermostats equipped with an occupancy sensor cover provide advanced active occupancy logic, which will automatically switch occupancy levels from Occupied to Stand-By and Unoccupied as required by local activity being present or not. This advanced occupancy functionality provides advantageous energy savings during occupied hours without sacrificing occupant comfort. All thermostats can be ordered with or without a factory installed PIR cover.

If you intend to work with this device and driver, it is strongly suggested you get the BACnet Intergration Guide document for this device: 63-4524.pdf as recommended in the device documentation.

This module was developed using the upm::BACNETMSTP library, based on libbacnet-stack 0.8.3. Both libbacnet 0.8.3 and the upm::BACNETMSTP libraries must be present in order to build this module.

It was connected using an RS232->RS485 interface. You cannot use the built in MCU TTL UART pins for accessing this device – you must use a full Serial RS232->RS485 or USB-RS485 interface connected via USB.

// You will need to edit this example to conform to your site and your
// devices, specifically the Device Object Instance ID passed to the
// constructor, and the arguments to initMaster() that are
// appropriate for your BACnet network.

// if an argument was specified, use it as the device instead
if (argc > 1)
defaultDev = string(argv[1]);

// Instantiate an TB7300 object for an TB7300 device that has 73001
// as it's unique Device Object Instance ID. NOTE: You will
// certainly want to change this to the correct value for your
// device(s).
TB7300 sensor(73001);
// Initialize our BACnet master, if it has not already been
// initialized, with the device and baudrate, choosing 1000001 as
// our unique Device Object Instance ID, 2 as our MAC address and
// using default values for maxMaster and maxInfoFrames
sensor.initMaster(defaultDev, 38400, 1000001, 2);
// Uncomment to enable debugging output
// sensor.setDebug(true);

Constructor & Destructor Documentation

TB7300 ( uint32_t  targetDeviceObjectID)

TB7300 constructor

targetDeviceObjectIDthe unique Instance ID of the Device Object. This number is used to uniquely identify devices on the BACnet network, and ranges from 1 to 4194302. This is not the device's MAC address, though on some devices, the MAC address may be used as part of this number. On the TB7300, this number depends on the model and the MAC address.

Here is the call graph for this function:

~TB7300 ( )

TB7300 Destructor

Member Function Documentation

void update ( void  )

Read current temperature from the sensor and update internal stored value. This method must be called prior to querying the temperature. All other values in the device must be queried directly via the appropriate BACNETUTIL::get*() methods depending on the object of interest.

Here is the call graph for this function:

float getTemperature ( bool  fahrenheit = false)

Get the current temperature. update() must have been called prior to calling this method.

fahrenheittrue to return the temperature in degrees fahrenheit, false to return the temperature in degrees celsius. The default is false (degrees Celsius).
The last temperature reading in Celsius or Fahrenheit.
void setTemperatureScale ( bool  fahrenheit)

Set the device temperature scale to Celsius of Fahrenheit. For devices with an LCD display, this will affect which scale is displayed. When changing the scale, it may take several seconds for the setting to take effect.

fahrenheittrue to set the scale to fahrenheit, false for celsius.

Here is the call graph for this function:

bool getTemperatureScale ( )

Get the device temperature scale.

true if scale is fahrenheit, false for celsius.
