Recirculation pump for the hot water.

[William E. Siegel]

Agreed

[Marcel R. Cyr]

Where is the wire?

[Michael R. Boyett]

That more closely resembles a tempering or mixing valve to prevent scalds at the Hot water supply to that fixture. It may be a Sorel (German?) ESBE model. It does appear to be supplying the tempered water in the down direction which does not make sense. I know these are used on radiant floor heat as well.

Never seen one, cool. The down flow is confusing though.

Yes, based on the arrows on the label, it looks like a mixing valve with expensive pipe adapters.
