The tenant can push buttons all day and it will do nothing if you choose to disable the keypad....Great post, but one point to clarify.All thermostats are sensing ambient temperature in some way, so all are vulnerable to tenant tactics that manipulate the ambient temperature in the vicinity of the thermostat; some of those tactics appear in my previous post on this thread.So the word "only" in the quoted post assumes that there is no such tampering going on.

An A\C can only cool 20 degrees below the outside ambient temperature.

Step downlight LEDs should create good ambient evening lighting.Third floor vaulted ceiling and skylight tube.Master bedroom shower.

Another best practice is to make use of several types of lightning including ambient (overhead), task (pendant) and accent (table).

Whatever camera you use, you need to have HDR (High Dynamic Range) capability - either in camera like the 5D Mk III or in post processing, like Lightroom or Photoshop.The two main reasons I like the 5D Mk III are that I can push the ISO absurdly high, allowing me to shoot *hand held* in ambient light. 

The electricity is used to extract the heat from the ambient air, bit actually heat the air.

Typically an inspector would not test the A/C system if the ambient temperature is below 50 degrees which could be the case in Feb/Mar in Utah.

With regards to heating from the heat pump, if you are concerned, as your contractor for a unit with low ambient capabilities. 

And, MassSave mentioned that there are models that suck in the ambient air and dehumidify, are these worthwhile?

The electric company plugged in the new meter and drove off, the fire started shortly there after (no interior inspection occurs and the tenant doesn't have to be home).The investigation identified the kitchen stove wiring as the source of the fire (I personally think the stove may have been in use at the time of shut-off and was left on so the sudden restoration of power caused arcing), wiring was not ruled out so an electrical inspection was required by the city and they concluded all wiring in the unit (romex) would have to be replaced due to ambient heat exposure.
