Honeywell TL8230A1003 Line Volt Thermostat 240/208 VAC 7 Day Programmble

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)

This is a full feature thermostat made for line voltage applications. We have 240 volt baseboard heaters that operate off of thermostats in the 240 volt line between the main power panel and the heaters. Most thermostats operate off of low voltage but baseboard heaters usually have thermostats in the power line. This type of thermostat was not available in local hardware stores of electrical supply stores. I ws glad to find it on Amazon. The installation was easy—four wires from the thermostat attach to the four power wires in the junction box. I used a volt meter to make sure I was making the right connections, but it was not really needed because I wired it up exactly like the old thermostat. Programming is well explained in the instructions and wasn’t difficult. This thermostat is much better than my old one. It works silently and maintains very steady accurate temperature. It isn’t always turning on and off like my old thermostat.

This product works well and was easy to install, with the wiring clearly indicated on the back of the product.There are many, many options for the temperature programming. The simple exterior of the product belies the fact that there are two columns of buttons running to the left and the right of the center screen, hidden under flip-panels. Programming is not intuitive and requires some study of the manual.

I have a handful of these thermostats as I have the famed ceiling cable heat. These thermostats work great and are the relays are nearly silent. The display you will love as Honeywell did a very good job showing all pertinent information. You can quickly see the time, the actual temperature, the temperature mode the thermostat is operating in (Day or Night), and the time period at the bottom (Wake, Depart, Arrive,Sleep), along with a handy bar graph to show how much power is being applied to the heater. If you press the large button at the bottom it will turn on the backlight for low light or night viewing (and the green background makes the numbers easy to see). I only wish Honeywell would make each of the four program modes settable for temperature. Unfortunately, there are only two temperature settings corresponding to the Day or Night temperature modes. OK, three if you count vacation mode, but this mode is not programmable. Normally the Wake and Arrive modes are set to your higher Day temperature, then the Depart and Sleep modes to your lower Night temp. Honeywell calls the Day mode "Comfort" mode and the Night mode "Economy" mode. Anyhow, it comes down to four time periods but only two temperatures. This thermostat would be ideal if you could program each time period to a separate temperature. Maybe in the next future model...Side remark: If you are asking how to hook this up or what the red wire is for, you really should not be trying to do the installation yourself. Please save your house or possibly your life and hire a professional electrician.
