An arrangement for handling communication messages in a building control system includes a communication circuit and a control device. The communication circuit is operable to generate first message and provide the first message on a communication network addressed to a remote building control system device. The communication circuit is also operable to receive a responsive message from the remote building control system device via the communication network, the responsive message generated by the remote building control system device responsive to the first message. The communication circuit is further operable to perform a first operation if the responsive message is received within a first time-out period, the communication circuit operable to perform a second operation if the responsive message is received after a first time-out period has expired. The control device is operably coupled to the communication circuit and is operable to use information from first message in a first application. The control device has a second application operable to generate a plurality of different time-out period values corresponding to a plurality of building control system devices, the plurality of different time-out period values including a value identifying the first time-out period the second application of the control device is further operable to provide information identifying the plurality of different time-out period values and their corresponding building control system devices to the communication circuit.
