Research has shown that heating for household contributes to a substantial component of the utilities.

So it is important that you take note of your heating usage in your household as well.

Knowing that I provide reviews of green products for my readers, a friend has recommended me the Lux TX900TS programmable thermostat as a good product that can control your household temperatures to prevent unnecessary changes.

With this in mind, here is my unbiased review of this Lux thermostat.

Benefits Of Owning A Lux TX9000TS

Clear Backlit Touchscreen Display

The Lux TX9000TS has a large blue electroluminescent display allowing you to read your programmed settings clearly, even under low lighting conditions or at night.

Simple to Use

The Lux TX9000TS is programmed by a simple menu-driven software with intuitive touch-screen commands with clear operator manuals to help you set up your heating/cooling schedule.

7-Day Programming

The Lux TX9000TS allows you to customise your household’s heating and cooling schedule differently for 7 days (1 week). Within this programming schedule, you can also further program your settings differently for 4 periods within a 24 hour time frame.

Simple Installation

The Lux TX9000TS can be installed easily over an old thermostat or as an entirely new thermostat. It can also be installed on soft surfaces like plasterboard albeit a few simple modifications.

Compatible with Most Systems

This Lux thermostat is compatible with most heating and cooling systems that include the following:

  • Most 24-volt heating and A/C systems
  • Single-stage for both heating-only or cooling-only systems powered by gas, oil and electricity
  • Single stage heat pump systems
  • 2 wire heat only hydronic systems (hot water baseboard & radiator)
  • Millivolt systems (wall heaters / furnaces and gas fireplaces)
  • Heat pumps without auxiliary heat

But it is not suitable for the below systems

  • Multi-Stage Heat Pumps
  • Wire Hydronic Systems
  • Line Voltage Systems (120 VAC)

However in view of the high compatibility ratio, it still makes the Lux TX9000TS an ideal DIY and green installation in your household to help you cut down on your utilities.
