Heat Pumps and Electric Heating - Tempstar blows cold air

My friend has a tempstar unit which is a single packaged heat pump right? The blower part is on the roof but there should be a unit on the inside in the attic right?
Because when I found the manual here
http://icpindexing.mqgroup.com/documents/076419/51801100100.pdf
it doesn't really show what kind of unit should be in the attic.

I'm assuming the heat coils or strips would be in the attic.

This is the problem- it's blowing cold air and the force of the air that it IS blowing is weak. There's no emergency heat or auxillary heat button on the thermostat. When the "cool off heat" is set to "off" and then the Fan is set to "on" nothing happens...
but when the "cool off heat" is set to "heat" and the fan is set to "auto" it eventually comes on maybe 10-15 minutes later. Earlier this season it was working fine..just recently started acting up and blowing cold air.

I've gotten so much help here and have been bragging about how useful this website has been to us with our units (fixed air and heat this season! thanks!) so now I've been asked to research it a bit. Hoping we can help our friends get some heat.

Thanks for anything you can suggest. Pressed the reset button on the thermostat. The fuse looks fine. The fuses in the outside unit (rooftop) were tested and are fine...flipped breaker switch just in case it could magically reset something..no such luck.

THanks!

That is a all in one unit. You dont have anything in the attic but the duct work off it.
Id ask first how is the air filter is it new and clean???

force of the air that it IS blowing is weak.
is the AC coil clean ??????

You should have EME there what do you do when it goes into defrost for heat???

but when the "cool off heat" is set to "heat" and the fan is set to "auto" it eventually comes on maybe 10-15 minutes later.
Now the fan came on but why didnt the heatpump? check the relay and sequencers inside the unit. It will all be up on the roof.
If you go to that www you gave . It will show you that you have to have EME heat in the tstat.

;)

They are using this robertshaw thermostat

with no setting for eme heat. We should start by replacing that, right?
this is the first winter in the house.

I know the filter is clean. we'll take the cage off today to check the coils and then check the relay and sequencers.

thank you!

That pdf you gave has how the wire set up for the tstat on that unit should be.

"You should have EME there what do you do when it goes into defrost for heat???"

I don't know. Seriously. On the thermostat in the house-there is only a selection for "heat, cold, off" and then for the fan "auto, on". Nothing more.

When people are talking about turning on their emergency heat where the heck do they do that? at the thermostat in the house? There's no button for that.

Inside the house..the thermostat is wired White to W, Yellow to Y , Green is to G, and Blue is to O. Nothing is jumpered and there's no W1 or W2 there is an RH and a B but there's no wire to them.

We couldn't get on the roof before nightfall so this weekend we'll get up there. No one is freezing to death. It's Arizona. They also have a fireplace.

The other day the heat worked for about a half an hour. I'm betting those coils are yucky dirty.

I'm going to look up a trouble shooting guide for that unit. The installation guide is useful but we obviously need more. Gah!

Thanks Ed Imeduc. I don't know what we'd do without you!
