This is a new old stock control board for a Taco 008-VVSF6-IFC circulating pump. This was in a new pump and some genius pulled the cartridge out for a service call. The pump was new so even though the apparent build date on this is April of 2011 it has never been used. Do they make these anymore? I can't find a price for one anywhere. Appears to be a 0-10VDC control board. I tested it and it turned on a 007 pump. Assuming you would buy this to replace an existing part. Please look at the pictures and verify this is not only identical to what you currently are replacing but it will also function properly with your equipment.
