The relay box will normally be found mounted close
to the boiler.
What does it mean when the Relay Box green LED is ON?
The green LED indicates normal operation of the radio frequency system. When the
green LED is ON the boiler is also ON. When the LED is OFF the boiler is OFF.
When do I need to use the push button?
You should use the push button to control your boiler only when the RF
communication is lost (see Troubleshooting the EHE0200361).
