I'm not sure. I've only used a couple of 2 ton units.
One thing that I have noticed in the den, is a pretty short warming cycle, when it's mild out.
Yesterday and this afternoon, I noticed the ODU fan only ran for 30-50 seconds before shutting down.
On the TED power monitor, it shows 30-60 watts, then creeps up to 450-480
for 30-50 seconds and then back to 30-60 watts again..

The remote's heat sensor is enabled, and the remote only sends it's data once every 5 minutes.
So, when it's mild, I guess the system must be using it's IDU heat sensor to
keep it from over-heating the room.

Or, maybe an increase in heat to the remote, will trigger it to send a data bust earlier than normal.?.


When the ODU shuts down, the IDU fan stays on a while, since the coil is still warm.
After the coil cools down some it switches to super-slow-flow.
It uses super slow to slowly move air past the built in thermistor.
It's also slowly filtering the air in the room.

Sanyo#1 is heating a much larger space, and runs longer, when it comes on.
Maybe 4 or 5 minutes on mild days. But it might stay off longer too.

Anyways, the Sanyo can throttle WAY back and work like a little 4k BTU wall AC,
but not use that much power..(300-480 watts).

So, if you do get one too big, you should not end up using excessive power.

You should look at the specs of the units.. I think there might be a low end,
where you can't use any less power and still be pumping refrigerant.

I'm amazed to see my both units cranking out some good heat in the morning, running at 900 watt total.
Then it gets warm and they slow down.. 60watts total in idle mode..
(Heaters on the crankcases).
