The Lux TX9100E 7 Day Programmable Thermostat has received outstanding reviews from consumer groups and Amazon purchasers. It costs only $55 and yet has the power and functionality of a much more expensive programmable thermostat.

The Lux TX9100E 7 Day Programmable Thermostat is compatible with 2 stage heat and 1 stage cooling, heat pumps with and without auxiliary heat, up to 3 wire hydronic systems, gas, oil and electric. Unlike other Lux Products programmable thermostats it can be powered by the HVAC system.

The Lux TX9100E has a large mercury free backlit display and uses Lux's patented speed dial system for easy programming. It offers a program for every day of the week and within each day 4 periods.

The thermostat also comes with a range of useful functions such as temporary override, vacation mode, smart recovery (called smart response on Honeywell thermostats), swing control and filter monitor. It is an extremely accurate programmable thermostat that is approved by Energy Star and that comes with a 1 year warranty.
