BINDING / RE-BINDING PROCEDURE
The RF link between the Room Thermostat (DT92) and
the Relay Box (BDR91) in Honeywell system packs is
pre-configured at the factory and therefore both units
should be installed at the same site. If products from
individual system packs are separated, or mixed with
other pre-configured system packs during installation,
or a faulty unit is being replaced, the desired units must
be specially configured to allow them to communicate
with each other. This process is called Binding.
The sequence of operations required is:
1. Bring thermostat close to relay box (around 1m.)
2. Reset stored data in relay box
3. Put relay box into binding mode
4. Reset stored data in room thermostat
5. Put room thermostat into binding mode
6. Bind room thermostat to relay box
Reset Stored Data in Relay Box
Press and hold the push button for 15s to reset the
stored data in the BDR91 relay box.
The red LED will give a brief flash every second to
verify reset has happened.
Put Relay Box into Binding Mode
Press and hold the push button for 5s to put the BDR91
relay box into binding mode.
The red LED will flash 0.5 seconds on, 0.5 seconds off
to verify it is now in binding mode.
The BDR91 relay box will remain in binding mode for 3
minutes, before generating an error message if no valid
binding instruction has been received.
It must be put back into binding mode if further
attempts to bind are required.
