I have two thermostats wired up one for propane and ac the other is for just the blower (for heat exc from outside boiler)

Now I need help getting the blower to run on high.currently it only runs at 700 RPM,
Takes for ever to heat up the house.

Anybody have any ideas?

Wow. I have the same setup with the opposite result. Air handler runs on high when tstat calls and moves the air so fast it almost seems to cool it down. I haven't had a chance to look at it yet, but I think its relatively simple. When the guy put my propane furnace / AC in, he set the a/c to run on high and the heat to run on med. or low. (can't remember which one) Someone here may already know how though. Glad you asked the question though.

Its driving me nuts. It works great when I run the propane. This is all brand new stuff had a flood in the basement so had to replace everything

You have to activate the y terminal to get the fan to speed up. You can use a relay to block the wire between the y terminal and the outside compressor.
