intermittant Siemens RDJ10RF/SET fault?
RDJ10RF - tried the reset procedure. Have a solid green light. Works in a morning to turn heating on 'preset 1' turn off 'preset 2' then I use 'comfort setting if I need it before it switches on in the evening. Put it back to auto after 'preset 3' all ok - Then the dam thing just turns off anywhere between 6.30pm and 9pm. I can't seem to do anything with the transmitter no heating unless I use the 'override' button on receiver every half hour or so. Next morning switches on at 'preset 1' and we start all over again! Any idea why I'm having this problem only in the evening?
