Communication loss (Only Intelligent thermostat) (ATW-RTU-02/03)
In the event of an RF communications loss, the LED on the RF Receiver will indicate which type of fault has occurred.
• If there is a communications fault between the RF Receiver and the Room Unit, then the LED on the RF Receiver will
flash red for 0.1 sec ON every three seconds.
• If there is a fault in communications between the boiler or System Controller, then the LED on the RF Receiver will flash
3 times quickly and then be off for three seconds.
• If there is more than one Room Unit installed, as in multi-zone systems for example, and communications is lost with
one zone, then the red LED on the RF Receiver will flash two times quickly and then be off for two seconds.
• If there is more than one Room Unit installed, as in multi-zone systems for example, and communications is lost with
both zones, then the red LED on the RF Receiver will flash once for 0.1 sec ON, and 0.9 sec OFF.
Once the faulty device has been identified, replace as necessary and follow the re-binding procedure as described in sec -
tion Binding / Rebinding Procedure .
