Hydro air fan delay

wayne_11

I am using a handler to heat the second story of my house. there is no provision for any warm-up on heat call only a post purge. This zone will open in 120 seconds on call for heat. the valves I have contain a three wire aux switch (operates around half open/closed) So my thought is that the fan coil would have about a minute of circulation before the fan started if I used the aux switch somehow in the fan circuit. Does that make any sense? or should I add a control to the return of the coil? The coil will be about six to ten feet from the boiler.

Use a delay on make timer at the blower relay or an aquastat .
