Hi,
I’m having intermittent problems with central heating not kicking in when RF thermostat is calling for heat (Danfoss TP7000-rf). The CH1 lights red on the RX1 receiver but I don’t hear a click and the boiler (Vaillant 837 Ecotec) does not fire.
If i remove batteries from thermostat and press CH1 button then red light comes on but again no click or boiler firing.
This is an intermittent problem that started a few weeks ago...gut feel is the RX1 needs replacing, does anyone agree with this conclusion?
