After the summer (when it never started because the temperature did
not drop), I have now noticed it is not working
The transmitter bit seems to be fine, but the reciever has no light on
it, and reading that doc above suggest it should.
No idea when it failed.
There is an on/off switch on the receiver, but this has no effect. I
have inspected the electrical connections and they are all still fine,
and the boiler itself works fine for hot water, so it is getting
power.
Is there a fuse of some sort inside this receiver unit? Or any other
obvious reason for failure?
sure you haven't switched the CH part of the (seperate) programmer off
for summer and not turned it back on for winter? - that would show the
symptoms you describe...

No, the transmitter part shows that it thinks the heating is on.
(little fan symbol)
Read the instructions, it may have lost its 'pairing'.

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.

mmm yeah i don't mean the towerstat transmitter thing i mean the
programmer next to your boiler that the towerstat receiver is
connected to..... you with me?
JimK
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??
JimK
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.

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.
