Our heating is split into two zones each controlled by a Seitron DLP 201 M00 0SE 2 + 1 Relay Module which has worked flawlessly since installed in 2010.

However now the channels/circulator pump/signal strength LEDs have started continuously flashing quickly. The power green LED has remained constantly lit and is not flashing.

The troubleshooting section in the instruction manual doesn't mention all LEDs flashing as an error condition, however it does state that either of the channel indicator LEDs will flash when the channel is in alarm state and not receiving a signal.

I've replaced the batteries in both thermostat transmitters but this didn't help.

Any help or advice on what else I can try very much appreciated!
