Tools and Hardware Reviews of Lux Products ELV4-005 Programmable Thermostat for Radiant Heat
Customer Review: Fully Featured - Best line voltage thermostat available at the price
Summary: 5 Stars
It is difficult to find a good thermostat for line voltage systems. Usually those of us stuck with these heaters either can use an inaccurate mechanical thermostat, or have to pay unreasonable prices for an electronic one.
Wiring on this unit is simple. Two wires are permanently attached to the thermostat, and two wire nuts are provided. It is made to install in a normal electrical box with the usual two screws (also included), so it can be easily used wherever a standard mechanical thermostat has been installed.
It comes in two pieces. One piece includes the relay, which protrudes back in to the electrical box a small distance. If there is a lot of other wiring in your box, you'll need to push it to the sides of the box, but it shouldn't be a problem. It takes up less space in the box than a wall switch. The other half is the actual thermostat, which connects to the relay with a couple of pins, and is powered by a pair of AA batteries. Also included is a wide trim plate, which can optionally be installed behind the thermostat, to cover up any uglyness you may have on the wall surrounding the electrical box.
I used this with a 240v wall heater, and it's worked wonderfully. The thermostat is fully programmable, with 4 time periods per day, as well as separate weekend/weekday schedules. If all of that doesn't appeal to you, just press the "hold" key and you can use it like a conventional thermostat. It is quite accurate, totally reliable, it keeps the temperature within 1 degree at all times. It doesn't seem to be affected by humidity or any of the things that influenced my previous mechanical thermostat.
The current setting is always displayed on the right portion of the display next to the up/down buttons; the right portion alternates between the actual room temperature and the current time. The 2 AA batteries are replaceable without removing the unit from the wall, although I have never had to replace them.
All in all, I highly recommend it. An excellent upgrade and far superior to old mechanical thermostats, and has all the important features of the more expensive models. However, as you can only program weekend/weekday schedules, it will not work well for people who do not keep a regular M-F work schedule. It also lacks a backlit display, so adjusting the temperature requires having the lights on.
