Very simple to get set up.
This is the best T-stat I ever had for electric. baseboard heat. Quiet not all that clicking and maintains a very steady temp, within 1 deg of what it is set for. Also when power goes out it must have a memory, it stays set to what ever temp you had it set for. The power was out for 7 hours and when it came on it resumed and every thing stays the way you set it. Worked so good I ordered 3 more for my other rooms.

This type of thermostat is us control of our heating system in a way that no other thermostat we ever owned. Just love it. Would recommend it highly.

I was looking for a digital thermostat for my line voltage heating at home which none of my local stores carried. Did some researching online and found this compact unit. The pricing for even a comparable unit was way under the other competitors. Their detailed instructions were very easy to understand. Install time only took a matter of minutes. Programming and setting up the unit was just as easy. The winter months here in Chicago can become very brutal and send your heating bill skyrocketing. I have now had this unit installed for three months and can say that out of the three units I've purchased, it has already paid for half of it. I had one unit received with a stripped out screw that holds the digital face plate on. Their customer service was very polite and quick to respond for the mistake. I had the xmlnsnt unit on my front door in a matter of days. I would recommend not only this unit but this company for anyone's needs at home.

I bought these for my mom and she passed away before they were installed. I plan to have them installed within the next two weeks. I filled in the above information so I could let you know what is going on.

And now I am planning to buy three more, one for each room and save even more money on our electric bill.

Need a Honeywell line thermostat and you had one at a reduced price and free shipping. Product is performing great. Can set it for heating up before I come home and turn the heat down at night. It was what I needed to update my heating system. Has a lot of options for setting the heat for different days an times. Also because I need some type of control of the heating times because children do not always turn the heat down when they leave the room for the night. This unit is a baseboard heater in my basement.

Works great, I like the fact it controls the output of voltage to the heater. Before it was either On or Off. Now it runs at specific percentages of the total capacity. I see this as a large savings on my power bill. Also keeps the temperature very steady through out the day.

I used this with a cadet hyronic system and I really like it especially once I figured out the programming.
