5.1 Binding / Rebinding Procedure

The binding operation described below is required if:
• Any of the system components (room thermostat or relay box) are replaced.
• The relay box has incorrect or no binding data stored (e.g. when pre-bound system pack components
have been mismatched).
NOTE: During the binding procedure keep approximately 1m distance between the room thermostat and
the relay box.
To bind/rebind:
1. Press and hold the relay box push button for 15 seconds to reset any previously stored data. After 15
seconds the red LED will change to flashing 0.1sec on/0.9sec off.
NOTE: After 5 seconds the red LED will start to flash 0.5sec on/0.5sec off, but continue to hold the
button).
2. Release the push button.
3. Press and hold the relay box push button for 5 seconds to enter the binding mode. The Red LED will
start flashing at 0.5sec on/0.5sec off to confirm the binding mode has been entered.
4. Press the OFF button on the room thermostat. Then press the
the button. The unit will display InSt and 'CONTROL BINDING'.
5. Press the green button to send the binding signal out to the relay box. The red LED is switched off
to confirm successful binding operation. If the red LED still flashes push the button again until binding
is successful.
