Radio Frequency signal flashing????

Hi, recently our boiler has not started along with the timer. The radio frequncy thing on the control panel flashes along with the light to say its on, it starts up fine when you press OK but need to do it manually. Tried changing the batteries in the thermostat control but that did nothing. Help please!!!! Its a Worcester Bosch Greenstar 25Si

Ahh i see. It turns out i have a DT20RF thermostat with twin channel MK1. Ive re-calibrated it now and ill see if that works.
Once again, thanks for the help!

There just boiler only instructions you need To go to the bottom of that page instead of clicking on the boiler manual...you will see it says accesory literature...You need to be in there.....good luck

No they're not the right instructions. Ive found the correct instructions (http://www.worcester-bosch.co.uk/cache/file/275/user-manual-for-greenstar-si--manufactured-aug-08---july-09.pdf) but it doesnt say in there how to re-calibrate.
Thanks for your help, im going to contact technical support tomorrow to see if they know the problem, im sure its something very simple

I've no idea if its a Drayton stat, it doesnt say anywhere on it what sort of stat it is. The reciever is inside the boiler i assume so i can't press any buttons, without taking the front of the boiler off i wouldn't know. Do i need to recalibrate? Could that be the problem?

Sounds like a drayton stat if so....take batteries out of stat and wait for display to go blank...turn electric isolation switch off for 5-10secs then back on...press and hold the 2buttons on the receiver for about 10secs...reinsert batteries into stat this should recalibrate the stat and receiver...if it's not a drayton one let me know

Is the receiver actually on the boiler or mounted next to it?

Gary, November 2010

No its a digital roomstat, just has two buttons to change the room temp up and down and thats it

Marc, November 2010

Is it the mechanical roomstat with 2thermostats on?
