A temperature value of 396, equivalent to 99ºC indicates a sensor not fitted or sensor fault, the appropriate bit will also bet set in the status register (tags 15-23) if this is a fault condition. Page 19 of 20 Doc: TC02 O&M Final Status: issue: 11 ©TB Controls 2011... -
Page 20: Fault Finding
Make sure all network cables lengths have the shield wire connected to local earth at one end (jumper link on TC02). An unconnected shielded cable is worse than an unshielded cable! Check network address with BMS system. Each TC02 controller that is connected to the network must have a different MODBUS address (default is 1).
