i changed batteries in boss thermostat and discovered that the boiler wasnt responding to thermostat, even though thermostat appeared to be working fine, giving me the black triangle, which means it should be on
I tried resetting thermostat box and also boss unit attached to worcester bosch boiler, which is only 3 years old but to no avail - help please!!

they all have different orders for resetting..
if it is seimens RDJ10RF then you set to 'AUTO' then press 'set' on reciever (by the boiler) then press ' learn' and then 'set' on the back of the remote ( you have to take the back off!!) then the green light should come back on and you will be fixed..
