Yes, you can. You would just connect the primary connection of the transformer, pump power and fan power all together and power it from the thermostat. Then connect the secondary side of the transformer directly to the zone valve. When the thermostat calls for heat it will turn on the fan, pump and zone valve.

Will that inter fear with the existing hook up for the other zones when they power the pump?

Oh, is there only one pump? For some reason I was thinking there was one just for this zone. If that is the case then yes, don't hook it up like in the last post.

We will need to know how the other zones are wired. I am guessing they are using the end switches and are in parallel so either will turn it on.
If that is how it is setup and you want to use your line voltage thermostat, connect it to control the fan and the new transformer but connect the end switch on the zone valve the same way the others are.

I did some looking around and found the thermostat in the basement.   So all I need to do is put that voltage thermostat on the fan line.

That will work if you don't need them tied together. If you want the existing thermostat to turn on the fan you can just use a relay.
