This very versatile programmable thermostat is a great alternative to purchasing a more expensive Honeywell thermostat. This thermostat will readily wire up to any single stage or two-stage heat pump system - electric or gas; my unit is a Rheem all electric two-stage heat pump system. Lux shipped the unit promptly and well-packaged. All necessary mounting accessories and clearly-written instructions came with the unit.Installation was a breeze. I must note that if you are a do-it-yourself type, I strongly recommend that you contact Lux and/or your A/C-heater manufacturer to compare notes on which color wire goes to which terminal on your thermostat when connecting the wires. Each system's wiring codes are different, and thermostat makers add extra connection terminals to accommodate as many different systems as possible. For example, in my Rheem system, I have a brown "C" wire that is used as a common for the thermostat and a blue wire that is used to activate one of the heater controls. I connected the brown "C" wire to the "C" terminal and the blue wire to the "B" terminal of the thermostat. In other systems, there is no "C" wire and the blue wire is used as a common. In this particular case, if you were to connect the blue wire to the "B" terminal on your thermostat instead of connecting it to the "C" terminal, you could possibly damage your system. Once wired up correctly, the unit is very easy to program - it takes maybe 15 to 20 minutes to set up a 7-day routine that once set, can be left alone and never touched again and it will provide you with round-the-clock automatic temperature adjustments that will save you money and keep your home comfortable.There is only one small negative to the Lux TX9100E thermostat. In some wiring applications, it may be necessary to insert a jumper wire between two specific terminals to correctly accommodate your particular system's requirements. Lux does not include this jumper wire in its package. You are required to make one yourself if your system requires it.
