No, the transmitter part shows that it thinks the heating is on.

That doesn't answer the question that was asked. Have you checked
that any programmer/switch before the *reciever* is also on.
Read the instructions, it may have lost its 'pairing'.
I'd check any batteries first then check the pairing (or more likely
just go through the pairing sequence).
I expect the light on the Rx only comes on when it has correctly
received a call for heat from the Tx.

my similar sounding Towerstat RF jobby turns from red led to green led
when heat is called.
...and of course when CH channek of programmer is "off" no LED at
all...... that's my guess--- OP??

apologies for slow response - internet failure

1) boiler and bolier controls all set ready to turn on when called by
the swiched live from the thermostat
2) Thermostat transmitter part is callling for hot water (fan symbol)
3) no lights AT ALL on thermostat receiver. From reading the manual I
posted I am expecting a permament red light, and a green light only
when heating is actively on.

So, as I said, it appears the termostat receiver has failed.

My sunvic did the same. They wouldn't sell me a receiver, or fix it, so
I bitched and moaned that I would never by sunvic again. They sent me a
free replacement.

I did fiddle with ity a bit and found the rail voltage was too low.
Something had shorted inside as when I set it up on a 9v supply it
worked, just not from the mains.
