Yeah we had a chilly night.. http://ecorenovator.org/forum/billia...html#post18416

I can't understand why your temp would drop to 62, if your remote was set to 70..
If your system (21,600 BTUh heating) is correctly sized for your home, then something is not working right.
(I'm assuming your home has good insulation and not a lot of sq feet to heat).

If the remote control was placed so it could communicate with the IDU,
(line-of-sight), it should have maintained 70 all night long. (At the site of the remote).

Did you press the 'Sleep Button' or 'Minimum Heat' button?
Are your air intake filters clean?

One thing I have learned about using ASHPs, is not to turn the temp down too low at night.
Because it's ductless, (a single-point heat source) tt can take a long time to restore the setpoint we want..

So, using Sleep mode or the timer isn't productive. Since you will use a ton
of kWhs to get back up up to comfortable temps.

Unless you have great solar input early in the AM, which will warm
up the house with hardly any help from the heating system.
