Is it safe to put "cool" and "fan on" to cool room instead of heating?

No problem want to know if thermostat can be set at "cool" and fan "automatic" to cool a room?

Is this a touchscreen thermostat? I imagine it is, but just want to be sure.

The second question: is the system currently set on auto? This means it will heat or coll to keep the house at a set temperature. If it is on auto you can toggle the temperature setting down so that you get more cooling. If it is set on auto and not cooling the house at all or does not change the indoor temp after toggling the temperature setting there is likely a malfunction in the thermostat or perhaps with the system itself causing it not to properly cool. One way to test it is to toggle the temp down and see if that cools the house (also if it kicks on the AC unit). You can also change the setting to cool and see what happens.

If the unit is malfunctioning you will need to bring in a certified HVAC tech to diagnose and fix the problem.

If you are asking how to cool an individual room as opposed to the rest of the house you need to determine if the system is zoned and how it is zoned.

At any rate, changing the setting from heat or auto to cool and adjusting the fan setting should not hurt the system.

To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.  To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.

I have the Panel and a couple of Z-Wave items with it (the lock, theamostrt and two light dimmers. Can I add more Z-Wave products? For example, I would like to replace the front porch light switch with Z-Wave so that I can operate it automatically as well.

Apparently, in real-life few underwriting selectiones are so easy or clearcut. When QuotesChimp make an application for insurance you reach the underwriting desk having a mixture of features that'll be thought to be possibly favorable (showing a low hazard to the corporation) or unfavorable (showing a high-risk to the corporation). The underwriters will think about your whole record account and choose whether, in general, you present an ordinary threat to the corporation (typical), a high-risk (sub standard), or a low jeopardy (favored). Favourite threats provided and will soon be rapidly approved the most favorable cost. Typical threats provided and will undoubtedly be recognized the conventional cost. Sub Standard threats may be declined, or approved in the problem which they spend an increased cost or, at times, they take lesser rewards.
