Vent damper wont open

I have a Vaillant water boiler home furnace. My aquastat stopped
switching on the circulator pump. Until I could get I could get a new
aquastat I disconnected the curculator pump from the aquastat
and wired it to a 120v plug and plugged it into a nearby house outlet and
ran the furnace. I got a new aquastat and installed it. The circulator
pump is spinning and the new aquastat appears to be working, but the
vent doesnt open and the burners wont ignite. Its as if they arent
getting any power. There is a loud buzzing from a relay that is mounted
just above the aquastat.
