Blower On Delay dantheman 10-16-2006

My Carrier 58MCA furnace has a 66sec Blower On delay. The problem is
that I have to have the fan running constantly to assist the HRV
Ventilator feeding the return duct. When the Blower Fan stops for
"warm up", the ventilator is blowing out the unfiltered return ducts,
sending dust and crap into the air.

Can I switch off the Blower On Delay? What if the blower is running
off of a FanHandler (so it's quite slow during normal Fan On)? Would
disabling the Delay impede the warm-up of the heat exchanger enough to
cause a severe performance problem?

How can the Blower On Delay be modified? After studying the wiring
diagrams, it seems that the feature is not field adjustable.

Peace, Dan

What's the fucking problem?
You say that you're running the fan continous.

Yes--but when the call comes for heat, the furnace automatically stops
the fan for 66sec while the burners light and the heat exchanger warms
up--then the fan comes back on. During this 66sec, my ventilator,
whose supply is connected to the furnace return, blows out the return
vents (since the furnace has temp. stopped pulling the return air).
Get it? Now, how do I disable this damn automatic "pause" in the
continuous fan??

Peace, Dan

Put in for a position with Carrier as a Design Engineer and re-design
the board to your own specs.
Im sure if you'd like, Todd H would be more than happy to help you
with those design changes.
