Kit for use with the 4iE
Step 6 - Control in event of communications error
18
+
The Kit for use with the 4iE has been designed to still provide heating control should
the communication between the Power Base and Boiler Receiver be interrupted.
With the Power Base and Boiler Receiver paired and the thermostat calling for heat, the relay
will be activated and the Boiler Receiver will show a constant green LED indication. If the
communication between the Power Base and Boiler Receiver is lost, the green LED will remain
on the Boiler Receiver for a period of up to 30 minutes.
If communication has not been restored after 30 minutes has expired, the Boiler Receiver will
indicate a communications fault by displaying a red LED flashing quickly.
To activate the relay whilst communication has been lost, press the power button on the Boiler
Receiver once. The LED indicator will change from a constant to quick flashing red.
To de-activate the relay whilst communication has been lost, press the power button on the
Boiler Receiver once. The LED indicator with change from constant red to flashing quickly red.
Once communication has been restored, the LED indicator will change back to constant green
providing the thermostat is calling for heat.
