Heating after fan stops running

Post by jelrod55 » Tue Nov 29, 2011 6:23 pm

I have finally gotten my Nordyne E1EHA-015 re-wired, it helped when I found the wiring diagram for the 4 to 7 Control Box.

Now since I replaced the control box with relays here is the problem that I have run into, when the heat signal (24V) is stopped the fan turns off but the elements are still on unti the Sequencer times out.

What would recomend as a work around to keep the fan running til after the elements de-engerize??

I solved the problem by adding a Off-Delay Timer and doing away with the heating relay that I setup to replace the 4-7 Control Board.

The timer is adjustable for the amount of time to allow the fan to run, I set it at alittle over 2 minutes. This gives the elements a chance to cool down before the fan stops running.
