Enquiry or Reviews
Hi,
I am looking at the series R valve, for a domestic hot water heat pump application. The documentation indicates that flow should be from A to B in heating, but I am unable to identify which port is A and which is B. Please could you confirm the port numbering and perhaps provide a schematic of a recomended install?
Thanks
