Honeywell Home RLV3120A1005 Digital Non-Programmable Thermostat for Electric Heat Only

No tiene muy buen control, no mantiene bien la temperatura. Si lo dejas en cierta zona, prende y apaga constantemente. O lo dejas todo el tiempo encendido o todo el tiempo apagado. Pero le cuesta demasiado mantener una temperatura.

Bought this to replace a broken thermostat. So far, it seems to be working perfectly. Easy to install and no fuss trying to figure out how to use it.

The Honewell RLV3120A1005/H is an extremely simple thermostat for two wire baseboard heaters. You set the temperature, and it holds it there until you decide to come back and change it again. I’m replacing an old Swan manual thermostat from the 60’s. It was a simple On/Off thermostat which worked off an expanding piece of metal. Accuracy was not its strong point as my room went from feeling like Antarctica to Guam in less than a half hour if I tried to set it to a measly 70 degrees. The heater was either on full blast or turned off. This made my room feel very stuffy and overly warm. There’s probably a reason for that but I’m no heating expert. I would have liked to get a programmable model but I didn’t want to spend too much (I’m renting the house from the college after all) so I settled on the Honeywell. Looked to do all I needed it to anyway. The thermostat feels pretty substantial. Upon opening it up you’ll find a large heat sync and some beefy circuitry to handle the baseboard heater. It’s rated for 1000 watts at 120 volts and 2000 watts at 240 volts. That’s a roughly 7 to 9-foot heater. The exterior plastic feels solid too. The buttons are very clicky but don’t have a very satisfying travel. Installing was a piece of cake. It has black two wires coming out the back, roughly 4-5 inches long which you connect to the baseboard heater wires in your wall. Color and order don’t matter. The box includes wire nuts for securing your connection and two screws for attaching the device to the wall. After killing the breaker (always cut the power to your heater before installing these things) I wrapped the wires together, used the nuts to secure the connection, carefully replaced them into the wall box, and screwed the thermostat in. The screws that come with the thermostat are very long and didn’t fit my wall box so I used the ones that secured the previous thermostat. Once it was secured to my wall, I slipped the top plate over the thermostat and switched the power back on. Worked like a charm. Operation is stupid simple. The display always shows the ambient temperature. Clicking the up or down keys once shows the temperature setting. Clicking them again changes the setting to the desired temperature. Clicking both keys at once brings up a setting to change from Celsius to Fahrenheit. When the heater is on the thermostat will display 1-5 little flame icons. The thermostat will throttle the heater to keep energy use to a minimum and make sure your room doesn’t get turned into an oven for the sake of a single degree. The flame icons indicate how intense the heater is running with five being blazing hot and one being warm to the touch. This throttling works great and the temperature is kept within around +/- 1 degree most of the time. When on full intensity, the thermostat can get a little warm to the touch (guess that’s why it has a heat sync), but not enough to worry about. Pros and Cons! Pros: • Super easy to use • Setup is super easy, just two wires! • Display is easy to read and clear. No noticeable fade from different angles. • Runs heater at optimal intensity for smooth heating and lower power bills • Stays accurate to setting • Does not click when turning on or off Cons: • Buttons are plastic and don’t feel all that great to press (nitpicking, they are fine) • Buttons on my unit feel slanted to the left. They are tilted away from you with a noticeable angle that you can feel when you press them. Weird design choice in my opinion so maybe it’s a defect? (Also nitpicking, they are fine) • There is pretty much no other functionality other than adjusting the set temperature (which is fine because that’s what it is) • The screws were very long and didn’t fit in my wall box so I had to use the screws from my old thermostat. Not a huge deal either but a little annoying. My heater is a simple 7 foot two wire electric baseboard heater with no forced air. Overall, this is a fantastic unit. If you are looking for a simple thermostat to run your baseboard heater then pick up the Honeywell RLV3120A1005/H

I really like these thermostats. So much so I replaced all of them in our house. I really like being able to see the actual temperature and be able to set it accordingly. I also like how they regulate the temperature by sending varying levels of power to the heater unit rather than a strictIy on or off funtion. I am not a fan of the old knob ones. This was easy to install. Just make sure you disconnect the power before working on replacement. I am very pleased with the value of the thermostat.
