I bought three of these to update the classic turn dial ones for my condo's baseboard heaters. They were extremely easy to install and were working away in no time. They maintain the temperature extremely well and I love the fact that they adjust the output of the heaters in order to save money on the electric bill. The 7 day programmable with multiple phases for the day is great. For people ordering from Canada like myself, yes it does show Celsius by way of a switch on the back side of the faceplate. These are designed in Canada and are actually just the Aube brand after Honeywell bought out Aube. Just a quick wiring instruction for those replacing the old turn dials (since the manual is a little bare on it). When you remove the old turn dial it will most likely just be the black wires connected to it (1 goes to the electrical panel and 1 to the heater) and the white wires are sometimes just attached to each other. Remove the black wires from the old thermostat and untwist the white wires. Move the live wires to one side and the heaters pair to the other. Attach the hot white and black to the L1 red and black and attach the heater's white and black to the Load red and black. (Black wires to Black and Reds to Whites)
