Can the unit be switched electronically from cool to heat? Or is the cold to heat option a wired connection on the rear of the unit?

Yes, when you are setting up the unit, you select either C or H. This is done electronically.

I use my thermostat to control the cooling range on an iceless cooler. Fiddling with the thermostat I have noted that it can go as low as minus 58 to well over 200 degrees F. The temperature settings are manually set.

Mine is hard wired to a wall switch. I think there are models that include external switch.

Have this unit in my bar. It is both Hot and Cold. However you could only hook up the cold supply and make it C only.

Depends on your system. www.white-rodgers.com has a search feature. search for 1f56n-444. you will find a basic heat/cool wiring diagram and other diagrams, electric heat, heat pump, etc., if needed.

Don't know - the unit i purchased did not have that switch - but works great!

I am not an electrician but I guess an inline switch is possible. However, the switch on the unit is a knob you turn, and where you position the knob determines what temp you get. Turning it all the way will give you max heat which is too warm for my shop. I set it in the middle so,ethereal when I turn it on, and go up and down when it is stable. My garage is 28 x 24 and it takes maybe 15 minutes to go from forties to 70ish. I just flip it on in AM, drink some coffee and eat breakfast, and then go to the shop. It is toasty when I get there.

Have you tried pushing the heat switch on the back of the unit to the "on" position?

You can actually program it to do either one. There's a setting in the back. I found this out by accident when I was wondering why the heat kept starting a few minutes early!

Yes, you can. There are 4 tabs along the top of the screen. Under the System tab, your options are: Heat; Cool; Off. Unfortunately, the auto changeover capability is not controlled here. Rather, you have to go to the Menu tab and drill way down, as follows: Menu/Preferences/Advanced Preferences/Heating and Cooling System Changeover. When you get to this screen, your options are: Manual; Automatic. This is where you control the auto changeover between heat and cool. My guess is that Honeywell has buried this capability so deep that many owners have not found it. My recommendation to Honeywell would be to put a checkbox right in the System tab to allow auto changeover or not, at the owner's discretion.

Switch is on the left side and this unit is sold as plug-in. There are other models that can be hard wired.

There is no actual "off" switch. If you plan to have a temp lower then what the stat is used for, I would suggest another model or add a switch to it.

Don't confuse the fan switch with the internal program mode of Heat vs Cool. The external fan switch acts like any old dumb thermostat. I do believe that you can read instructions on how to have it switch between Heat /Cool but it requires a 3 degree difference in the numbers for heat and cool. Myself I like to have the heat temperature be almost the same as cool temperature so I have not tried that feature. NOTE: You will have to carefully read and follow instructions. ( I really like this thermostat but haven't tried that feature)

These 5 answers are only half correct ,you can use thermostate . THey can be wired to turn on and off with heater set to a certain temp.

I have the battery powered version of this. But I assume it works same as the battery version which does auto switch from heat to cool mode.

I would assume you would be left with a "dumb" thermostat with no programming ability. Just Auto-Heat-Cool, and the temperature setting.

It has a cool setting that is switch operated, but the cold setting requires you to depress and hold the button. Hope this helps Michael

It should switch automatically based on your set temp. If it needs to cool down it will switch to cool and vice versa.
