All radiators okay apart from bathroom, I have replaced a portion of pipe with 15mm to 10mm as a kink was suspected of causing poor flow. Prior to connection, pushed a wire down the 10mm clearing out sludge. I have put flushing fluid in the expansion tank, and am due to drain down. since then, a bedroom radiator is hot at the base only and it was working okay. the bathroom rad is 'slightly warmer, and I have flushed it out. Is it sludge shifting around, the divert valve.(if applicable to bathroom rads) or the Tempus 7 programmer, which I have pinned out on 'gravity system' ie (B) It is an old system, and I assume this to be correct, as I have header and expansion tanks? The instructions mention a 'pumped system', is this in relation to condensing boilers? If the pin outs are incorrect, does it cause damage and any of the above problems?
Thanks in advance
