Help with adjusting blower time delay

I recently had both my air handlers in my house replaced with AirEase BCS2 units connected to Aquecoil units. I have noticed the time delay from when there is a call for heat to when the blower starts is a lot shorter (less than 20 secs) than before they were replaced. This results in cold air coming out of the vents for a while before it gets warm.

Are there any ways to tackle this? I checked the manual and it mentions there is a built in time delay but it doesn't seem to indicate how to adjust it (20 secs doesn't seem very long to let the coil get warm).

Any advice appreciated!

The time delay is fixed.. It may be possible to change the TD relay (if it is a plug-in model) or add an additional TD relay to make the delay longer.

Did you have these units modified for hydronic heating ?
The manual addresses electric heat and A/C but not aux uses.

Usually when air handlers are modified for hydronic applications a temperature sensor is installed on the incoming water line to monitor the temp and turn the blower on accordingly. A timed delay is not appropriate for this type of application.

Did you check with the company that did the install ?
