Drayton RF2 Clicking sound

[Diyisfun]

My Drayton RF2 receiver is making a rapid clicking sound, and the heating on neon is lit
The heating is set to off, the t/stat is off.
Last week I had the 3 port valve replaced & its been okm since then, so I dont think its related.

Any ideas as to problem.

They sometimes do that, the relays tend to let go easily.

Turn the power off at the main Central Heating switch, turn it back on and the clicking should stop. You'll probably need a new Receiver.

That seems to have sorted it. Thanks.
Im about to move, everything seems to want money spent on it now Im going..
