Symbio Service & Installation (mobile app) Overview
The Symbio 700 includes a built-in Bluetooth Low Energy (BLE) radio which is used to enable direct
access to the ‘Symbio Service and Installation’ Tool. No network connections are required as this
connection method enables a 1 to 1 connection between a single Symbio 700 and Mobile Phone that
meets the connection requirements.
Connection Requirements:
– Mobile Phone must have ‘Symbio Service and Installation’ Tool installed
– Mobile Phone must have Bluetooth (BLE) 4.2 or later (i.e. Samsung Galaxy S7 or newer, or Apple
iphone 6 or newer)
This is not information that can be read in the phones setting, if the Bluetooth version is pre 4.2 the
Symbio 700 won’t connect to the phone.
Bluetooth versions before 4.2 don’t meet Trane’s security needs.
Bluetooth version 5.0 increased connection speed and range (Samsung S8 and newer and iPhone X and
newer), note: the Symbio 700 uses Bluetooth 5.0.
– 4.2: 1 Mbps with a range of 10 meters
– 5.0: 2 Mbps with a range of 40 meters
Bluetooth Connection & Pairing
The Symbio Service & Installation Tool leverages built-in BLE security and device pairing processes.
To minimize opportunity for unauthorized access to the equipment, the following are leveraged as part
of the pairing process:
Unless previously connected, the BLE radio on the Symbio 700 is “OFF”; the Bluetooth LED will be OFF.
When a connection is desired, the user must “wake-up” the BLE radio on the Symbio 700 by pressing the
Bluetooth button on the user interface. At this time, the Bluetooth LED will begin flashing.
Numeric Passkey Pairing requires validation of a common 6-digit passkey on the Symbio 700 and Mobile
Phone before a successful connection can be made
Once the passkey is presented to the user on the Mobile Phone and on the Onboard UI for the Symbio
700, a confirmation must be made on both ends of the connection – by selecting “Pair” on the Mobile
Phone, and the “Enter” button on the Symbio 700.
Once the connection is validated, the user will have established a secure connection between their
Mobile Phone and the Symbio 700. The Bluetooth LED on the Symbio 700 will be solid ON.
The Symbio 700 will be included in the Bluetooth device list for the Mobile phone
