Well a part number and manufacture of the relay may help. A picture of it may also help. You can stick it in a scanner if a camera is not available. ------------- John DeRosa (Hotwaterwizard)

here it is, the brand I cannot figure out. it is not written anywhere I ordered an actuator online and this came with it.I like it because it is much smaller than taping two bosch relays together, and these are also solid state.

Don't quote me but im pretty sure these are what the wires are
(keep in mind it has 2 relays inside (lock and unlock))
blue (-) unlock input(to trigger unlock relay)
red (+) input for relay coils
green (-) lock input (to trigger lock relay)
purple lock/unlock normally open #87
green lock output #30
blue unlock output #30
white lock normally closed #87a
brown unlock normally closed #87a

Where did you order it from so we may see it online. It looks like a wireless Remote to me. ------------- John DeRosa (Hotwaterwizard)
