I have just replaced a Switchmaster 600 Controller with a Siemens RWB29 Controller, but for some strange reason I can't get any central heating to kick in.
I have wired the Unit correctly as per the instructions but when I switch the Unit on to CH or HW Manual, it ignites the boiler and then goes out in about 1 minute! I can hear the water pump start buzzing upstairs and the hot water cylinder is hot but i cannot get the boiler to stay fired up to get the central heating working.
I believe it initially worked on the first timed period that kicked in since installing, but I went to manually put the heating on for another hour or two and it just wouldn't keep working past the first minute.
The SwitchMaster 600's timer had gone so I replaced with this unit and right before i took the SM600 off the boiler and all parts were working fine when switched to constant so there can't be much wrong.
What am I doing wrong?
