Transceiver (Boiler Mounted)
1 During normal operation light (A) is on for Hot Water operation.
2 During normal operation light (B) is on for Central Heating operation.
3 If the Reset Button is pressed on the room thermostat the signal lights on the receiver unit will light. If less than 4 lights
are on either the room thermostat is too far from the boiler or the batteries in the room thermostat need replacing. At
the same time “M-050 S-050” is shown on the room thermostat. The number is another indicator of signal strength
– the lower the number the better.
