Simple, Dependable and Easy to Install Nov 23, 2007 By Tim
Winter weather has finally hit mid-state Illinois! I have been prepared and had the furnace all ready to go. My family returned home on Thanksgiving to a cold house. My old mechanical round style thermostat had finally failed (it had been acting up in the recent days).

I was a little nervous having to select a new thermostat and even more nervous about installing it. I'm not a real hands-on person with regard to home repair. But we were in a real need for something.

I picked this unit up very late on Thanksgiving night and proceeded to take it home (don't forget the 2 AA batteries). This unit was replacing an old round mechanical style thermostat in my home. The box says it would be a workable replacement solution and it was.

Installation was very simple (thank goodness I only have a 2-wire heating only system). I removed the old thermostat from the wall and removed the two wires (after powering off my system) from the old thermostat base. I followed the instructions that came with the Hunter unit (there are several easy to read wiring diagrams for the different heating/cooling systems) and attached the wires to the new base of the Hunter unit (after attaching it to the wall). The terminals are easy to read and hooking up the new one was snap. I attached the main unit to the wall base and installed the batteries. I followed the instructions to set the desired temperature and haven't had a need to touch it since. I had this unit fully installed in about 15 minutes (remember I'm slow since I'm new to this). Even for me this was easy to install properly. This unit will replace many thermostat styles and will control most heating/cooling systems (a full list is available on the package). Even better the factory default settings were the right ones to control my 2-wire gas hot water baseboard furnace.

The Hunter functions very well. Last night the outside temperatures dipped into the mid twenties while my family and I remained comfortable and warm inside. I have other thermometers (digital) in the house and the Hunter keeps the room temperature within 1 degree Fahrenheit from the set level regardless of how cold or windy it is outside. Something my old mechanical thermostat could never do.

The features of this unit are nice. The LCD screen is easy to read. The buttons are large and easy to use. The unit has a slim profile and looks nice on the wall (shouldn't be too noticeable in any room). The mode selection buttons and other controls are neatly hidden behind an easy to open swing out door on one side of the LCD display while the batteries are behind a similar door on the other side (no need to remove thermostat to replace batteries)! Operating instructions are neatly printed on the inside of the door housing the controls for easy access eliminating the need to search for the instruction manual later. I also appreciate the fact that the thermostat is electronically controlled and the unit doesn't have to be perfectly level to function correctly. This unit has functioned without problems and has been worry free for me and has kept my family warm and comfortable.

*** UPDATE 11-11-08 ***

We've recently moved to a new house and the Hunter served us well all year at the old place. It functions well and keeps the house comfortable. The batteries last a long, long time (a year plus).

I've just installed the identical thermostat in our new home to replace another round mechanical thermostat. This new home has a heat/cool forced air system where the old house was baseboard water heat. Again the thermostat installed very easily with the added wire diagrams. Installation is quite simple and the thermostat is easy to set up (just a matter of flipping a switch and adjusting the set point (one button).

I highly recommend this thermostat for an economical efficient means to ensure comfort for your home and family. The Hunter provided a noticeable energy savings on my old home, and I'm sure it will on this one too. Again, highly recommended!

Hunter 42999 thermostst Nov 16, 2010 By bob
Installed the new Hunter thermostat in just a few minutes with the help of the on line wiring guide. The hook was from a 6 wire system and 3 of the wires were not color coded or labeled with the same reference type. The web site provided the wiring diagram and the reason for the extra wires that were no longer to be used. There was concern that the 1 degree on/off would run the furnace too often and the instructions were clear on how to reset the function to 3 degrees. Sat last night with a comfortable warm 5th wheel and enjoyed the evening. Have let several of the other units that were having the same problem know the results. The old thermostat when set at 70 degrees would come on at 64 and shut off at 75 degrees.

RV Thermostat Feb 20, 2011 By F. Wickeham "fwickeham"
Excellent and reliable product at a reasonable price. I installed this in our Scamp 16 ft fiberglass trailer in less than 15 minutes. It works much better than the OEM mechanical thermostat. It would be nice to have batteries included with the product when shipped, but this way I know that the batteries are fresh.

Good Item Jul 01, 2010 By Cliff Nehamen
Easy to install and to use.....my error when purchased. I thought this unit had the option to set various times and days for on/off. Still a good unit.

Hunter 42999B Digital Thermostat Feb 07, 2010 By Joe
Nice simple non-programmable unit.

Pro : Large digital readout
Accurate
No mercury
Cheap
Works well if you have a "split" (two transformers) central air & boiler/furnace setup - Hook the white boiler/furnace control wire to the W terminal, the red boiler/furnace transformer wire to the RH(eat) terminal (make sure you have removed the RH to RC jumper for use on a two transformer setup), the green A/C fan control wire to the G terminal, the yellow A/C compressor control wire to Y terminal and the red A/C transformer wire to the RC(ool) terminal.

Con : No display backlight
