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.

or there is no power getting to the receiver perhaps because the CH
channel of your central heating proogrammer is switched off for
summer.... or maybe a wiring fault.... or maybe the receiver has
died ...

So deducing from what you have said :- the receiver bit was showing a
red LED since the weather warmed up in spring (and your transmitter
stopped calling for heat)? until it stopped showing a red led? if
that's the case and NOTHING ELSE has been changed, then yes I would
tend to agree the fault may be with the receiver.
