This review is for the "new" version, RLV4305A. I got this to control a 1200W Electric Radiant Cove Heater (QMark RCC12012C) that I installed to provide supplementary heat in a bedroom. For this project, a programmable thermostat was a requirement. If I let this radiant heater run continuously, it could cost me over $100/month in electricity, just to improve the heat in one room which I am mostly not in during the day. It really is silent. The box says it uses a TRIAC, which I learned is like a dimmer. So instead of clicking off when the room gets noticeably warm and clicking back on when it gets noticeably cold, this t-stat constantly raises and lowers the dimming level to tightly track the setpoint. There is some indication of this in the display, showing 0-5 heat wave squiggles, depending on how much power it allows through. The LCD display lights up when you press a button and stays lit for 10 seconds or so. Normally, it is completely dark. Without the backlight, it is still readable if there is enough ambient light, like during the day or with room lighting on. In normal use, it displays the current time and temp, mode and period, plus the squiggles mentioned above. Touching the temp up/down button once will show the set temp. Install is straight-forward if you are familiar with household electric service. This device is installed in series with the electric heater (like a wall switch) and modulates the line-voltage AC electricity that actually passes through both the thermostat and the heater(s). There are no low-voltage control lines here like a regular household thermostat has. I don't understand why there are 4 mounting holes in the unit. I used the 2 left holes with the 2 included screws to mount it to the left half of a 2-gang electrical box. I don't get why the other 2 right holes don't line up with the holes on the right side of the box, but even like this, it is plenty firm and secure and it completely covers the box opening. Programming is easy. "5-2" means you set separate Mon-Fri and Sat-Sun schedules, but nothing more sophisticated. By default, the M-F weekday schedule has 4 time periods (wake, leave, return, sleep) to program, but the Sat-Sun schedule only has 2 (wake, sleep). However, you can set times and temps for the 2 other Sat-Sun periods (leave, return) too. If you have a weird schedule you want to program, this might not be sufficient, but for most cases this should be good enough and easier to program. There are enough buttons with meaningful labels to make the work of programming it fairly easy. Rotate though the 8 periods with the "pgm" button, and change the time with the hr/min buttons and the temp with the up/down buttons. Finish/save by pressing the "⏎" button. Not rocket science. There is no "OFF" button or mode. "Manual" mode is a constant set temp like an old thermostat. The "Away" mode allows for a lower constant set temp (default 59f), presumably for extended time away from home. "Standby" mode is almost OFF, but it will turn on if the temp drops below 41f. In all the modes, it draws a tiny bit of power for itself. I have not tested this unit during an extended power outage, but it claims to remember the date/time for 5 hours or so without power. There is no battery compartment, so it must have something like a rechargeable battery or a big capacitor inside it. I'm very happy with the quality and the price is better than every other programmable line voltage thermostat that I've seen.

I have lived in my house for 5 years now and have used the old school dial thermostats the entire time I’ve lived here. I finally had enough of the issues that are associated with them and ordered a bunch of these for the rooms in my house. Looking back, I should have done this year one. These are such a massive upgrade over the old school dial thermostats. Programming is easy, works great, temperature is stable and accurate. Soooo much better. 10/10

This was the only control of it's type that I found several years ago that is designed to handle high voltage (240VAC) baseboard heat units directly. They are relatively simple to install to replace old bimetallic thermostats with a simple two wire connection. If you want to program heat to increase or decrease at certain times of the day, or certain days there is quite a bit of different settings for this, even separated by week days and weekends days. On the downside, they are more complex electronic devices than the more physical old thermostats and as such are more susceptible to power glitches. Power outage will require resetting time of day for each thermostat as well as Daylight Saving time unless that goes permanent. I got these to try to lower temps at night or in unused rooms, and there may be some savings in that but not to a great extent. Baseboard heat is quite inefficient and costly, and it still takes the same amount of BTU's overall whether it's maintaining or restoring the desired room temperature. If it were not for the added expense and complication of changing our whole power panel and some rewiring, I would have considered changing to a heat pump system with mini-splits and such over this. Whereas the old bimetallic thermostat is either full power on or off, these actually vary the voltage to the baseboard, which would seem to be better in terms of the loads on wiring in general, although as noted, you still need the same amount of power overall to heat your home to the settings you have made. These do allow you to change those settings, and within reasonable limits it could provide some savings, but it would be a while to actually recoup the investment in these units. Out of five I've had to replace two that stopped working over the last few years. Going forward, I would strongly consider adding solar with battery backup. An admittedly higher but more comprehensive investment in power for your home.[Edit] I gave this and extra star, and do definitely recommend it over the old style thermostat for anyone willing to spend more for a programmable system. I also consider it a plus that it doesn't require WiFi or an intrusive talking system that's actually monitoring you.

This is one of those rare times that I can say without reservation that I got exactly what I needed and it does exactly what I wanted. Replaced an old simple thermostat and now we don't have to choose between a high power bill or coming home to a cold house. It is easy to program and seems to work very well at maintaining a temperature without the multiple degrees oscillation of the thermostat it replaced. Should have done this a long time ago!
