Using the built in sensor didn't work so well.
Switched back to the remote sensor.
It seems this unit is made for a Big Room, not a whole house.
I've found that setting the remote to 70 degrees and
placing the remote in the living room works very well.
The living room stays dead on 70.. (If the remote not in the air stream).
But, Over-shoot in some areas can be a problem.
To make the Sanyo hit a certain temperature in a certain room,
I can compensate by adjusting the vent angle and remote Temp setting.
Of course an IR remote Repeater would solve the 'room' problem,
but where's the fun in that?
For now, I placed the remote in the hall (on top of the existing T-stat)
and ended up using 66 degs for the sleeping set-back.
Woke up this AM and it was 68 in the bedroom and 70 in the hallway. Nice!
The outside temps last night were in the high 20s and I believe the Sanyo never noticed..
It's so quite, I would not be able to tell if the outdoor unit was running real fast or not.
Need a 230V power usage monitor.. Otherwise, I'm not going to know
at what temperatures using the oil heat becomes cheaper..
(Because I'm not going outside to watch the meter when it's 16 degrees)!
I wonder if I could get a T.E.D. for Christmas? And put it on those two
new 230V wires in the breaker box??
So far, we have used Zero gallons of oil for heating. (Hot water only)..
We like it!!
