Hello, this depends what unit you have the control in. What is furnace make/model?
When you got the control did you check to see if it worked on your unit?
Your unit uses terminal 4 and 10 for the pressure switch..but the 405 has no provision on terminal 4
That is not how it works...in some furnaces there are multiple switches in the ps circuit. That is why I need the furnace number.
Some use rollouts, some do not. Some run ps through a vent switch. what I am saying is this board does not have a specific pressure switch out circuit.
I just checked your furnace and it will not accept this board. Your furnace needs more inputs that this board is capable of. 50A55-289 is the white rodgers that would work.
The one you have will not.
