What triggers defrosting in a Tempstar SmartComfort TX 5300?

Posted by on November 8, 2007, 11:35 pm

I am wanting to check to see if there is a possible problem created in
my Air Handler which might be happening when the Heat Pump enters into
a defrost cycle, but I'm not sure how long I have to wait until one
occurs.

The weather here is highs in the 50's and lows in mid 30's (northern
Kentucky).

I have seen two designs for triggering defrosts but I'm not sure which
Tempstar uses. I am suspecting its timed, but does that mean I would
only need to wait about 2 hours till one occurred, or do they only
start when the outside temps get down to a certain degree?

This is the unit with 10 year compressor warranty and R410A
refrigerant.

Thanks

Phil

Because the 'installing party' is who I suspect may have installed it
incorrectly and I don't trust whatever answer they would give me.

So I am asking here. I couldn't find any info on it on the internet,
so far.

Don't know that model in particular but here's some generalities. The
air handler is typically not aware that the outside unit has gone into
defrost. Most, no matter how they trigger a defrost cycle, they
usually will have a way on the defrost board to start the cycle.
That's so the service guy doesn't have to wait for one to initiate.
The paperwork with the unit should give some details or you might find
it on the web.

Bullshit, upon defrost every fucking heat pump condensor I've ever worked on
issues a call for heating.
