Power vent motor runs too long
I have a power vent inducer motor on my boiler and I want to install a control that still allows the pre- 5-10 second run time and an adjustable post fire control that will allow me to shut off the inducer motor 5 minutes after the burner turns off. The currently Fields control SWG-4 inducer is wired only to the device manager on the EK boiler, there are no other controls for the inducer motor. I have attached the wiring diagrams. Does anyone have a recommendation on a control device and how to wire it? Would the following control provide me with both pre and post run time?

The following is a Reply from previous post: Manager operation is as follows: If the burner locks out the 140º temp bar starts flashing, Inducer (if there is one), burner and circulator lights are on. After 20 minutes the burner light goes off and the monitor light comes on. All zone outputs (excluding ZHW) come on. After 25 minutes the inducer goes off.
If the power venter is non-EK supplied it is recommended to follow the manufacturer's wiring instructions, in which case the above timing does not apply.
