Hi,
I have a three-zone system, one HW, one radiator CH, and one zone underfloor heating (ground floor). The HW and CH are controlled by a 3-way valve, the UFH by a separate 2-way valve. It's all working fine, though was only installed a week or two ago.
My question is, what position is the 3-way valve in when there is no CH or HW demand from the controller?
I've just started running the UFH with the HW and CH turned off at the controller, and I _think_ (from feeling some of the pipes) that some of the radiators are coming on even though they're supposed to be off. I'm not certain though as it takes some time to cool down... So really trying to work out if this is a plumbing problem (3-way valve) or an electrical problem (wiring centre) before I phone the appropriate person!
Hope that all makes sense! Thanks in advance for any help you can give me!
