 Simple, Dependable and Easy to Install November 23, 2007
5 out of 5 found this review helpful
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.
 Two Fatal Flaws Make This Unit Unacceptable April 13, 2007
3 out of 8 found this review helpful
This thermostat has two flaws that are not revealed until you open the packaging and finish installation. First, the thermostat will simply not operate with a "low battery" warning. This will leave one without heat in the winter if the batteries fail at the wrong moment. Second, the unit will not allow temperature settings below 45 degrees Fahrenheit. This increases energy costs in the case where a 40 degree setting (for example) is desired to simply prevent freezing. With the combination of these two flaws, it would be risky to leave a home unattended for any period of time in cold weather.
It would be helpful if Hunter listed real specifications instead of marketing happy-talk such as "digital accuracy", "Up to 15% Savings On Energy Costs", etc. I suspect the other Hunter digital thermostats have the same flaws but there's no way to know until a unit is installed as neither Hunter (on its web site) nor Amazon provide this kind of information.
