No Heating, Just give hot water only! Alpha HE CB25

[f4fmayhem]

My Boiler is an Alpha HE CB25
It is giving out hot water fine firing up etc.
Thermostat turned up for heating nothing happens the 'B' led stays the same flashing every 5 secs (same as before turned up).
It's a wireless Thermostat 'SUNVIC Programable', battery is fine just not sure if it is talking to the boiler ? not sure how to check boiler with or without wireless thermostat controller (would try by-passing thermostat if I knew how).

Any Ideas ?

Cheers
Kev

I assume that if you drop the front control panel then remove back you will see the wiring connections. You will have to look in MI's as I dont know this boiler but you should be able to bridge out the room stat to test.

Your dead right as usual Dave

Kev you need to link terminals 1 and 2 on the boiler, Disconnect one of the wires from the controller
