BINDING / RE-BINDING PROCEDURE

6.1 Binding

2-way RF devices that communicate with each other achieve this through having each others unique addresses written in their memories. This allows
each device to know which other device to communicate with. The process of writing these addresses is known as Binding.
All devices in the pack are pre-bound at the factory. The binding operation is only required if:
- any of the system components are replaced
- pre-bound system pack components have been mismatched
- additional components are required for the application, e.g. BDR91T relay box for remote boiler application 95-3. In this case the
BDR91T must be bound to the ST9520C as a BOILER CONTROL (see section 6.6).

6.2 ST9520C Guided Binding Menu

The ST9520C is the communications 'hub' of the entire system, so other RF devices are bound to it and not to each other. ST9520C has a special
'Guided Binding Menu' that allows you to bind other devices to it in a logical way. Devices are bound into special 'slots' and there are rules governing
what can be bound into which slot. This ensures binding errors are minimised and applications are correctly set up. When in 'Guided Binding Menu'
the and buttons are used to navigate around.
Sensor binding (refer to section 6.5 for sequence of steps)
It is possible to bind 2 sensors to ST9520C in separate binding slots, a DT92E thermostat for Zone 1 and a DT92E thermostat for Zone 2. If the display
shows dashes it means there is nothing already bound in the slot. If the display shows 'bnd' it means there is something already bound.
Control and boiler binding (refer to section 6.6 for sequence of steps)
Once a valid sensor is bound, it is then possible to bind an output device, such as a BDR91T relay box. If this is to control remote zone valves for the
heating zones, then use the CONTROL binding slots. In the special case of controlling a remote boiler, use the special BOILER binding slot. When
this is bound, the Guided Binding Menu then allows a signal strength test to be initiated (refer to section 6.7 for sequence of steps).

General Binding Notes
• To bind 2 devices together, BOTH must be put into Binding Mode.
• With both devices in binding mode, you must send the binding signal from one device to the other:
- To bind a sensor, the signal is sent from the sensor.
- To bind an output device, the signal is sent from the ST9520C.
6.3 Guidance for Replacing Devices or Changing the Application
Note: if a sensor is removed, the binding for any output device associated with that sensor will be cancelled.
Situation
1. Replacing faulty DT92E
2. Replacing faulty BDR91T
3. Reconfiguring system by adding or removing BDR91T

Binding Action
• Bind new sensor over previous binding in SENSOR slot.
• Bind new BDR91T over previous BDR91T in CONTROL or BOILER slot and
remove faulty BDR91T from system.
• If removing BDR91T, cancel binding in that CONTROL or BOILER slot.
• If adding BDR91T, bind into vacant CONTROL or BOILER slot.
