Lux Products TX9000 Thermostat User Manual

Home

•

The Unit can be used with most 24 volt gas, oil or electric heating and air

conditioning systems, single-stage heat pumps or gas millivolt heating

systems. It cannot be used with 120 volt heating systems or multistage heat

pumps. Ask your dealer for other LUX thermostats to control those systems.

INSTALLATION AND OPERATING

INSTRUCTIONS

•

The Unit is programmable. There are four programming periods per day. Each

period can be programmed separately.

You can use the built-in time/temperature programs, or alter them to suit

your schedule. The Unit provides separate programming for every day of the

week- for both heating and cooling. You can override the programmed tempera-

tures for as little as one programming period or for an entire vacation.

In cool weather, when the system switch is set to HEAT, the Unit will maintain

cooler “set back” room temperatures to save energy. It will then change to

warmer “comfort” settings — all automatically, at specified times during the day.

In warm weather, when the system switch is set to COOL, the Unit will maintain

warmer “set back” room temperatures to save energy. It will then change to

cooler “comfort” settings - all automatically, at specified times during the day.

A large liquid crystal display shows time, day of the week, and room and set

temperatures. It will remind you when the filter should be changed in your blower

and track your system’s energy usage.

Temperature swing adjustment lets you fine-tune your system for maximum

comfort and economy.

A 4-minute minimum on/off time in COOL prevents your air conditioning

system from being damaged.

Two Energizer® or DURACELL® “AA” alkaline batteries (not included) are

used to retain your time and temperature programs.

TEMPERATURE SWING

A thermostat works by turning your heating or cooling system on and off

whenever the room temperature varies a certain number of degrees from the

set-point temperature. This variation is the “swing.” Your system should cycle

on about 3 to 6 times per hour. A smaller swing number increases the number

of cycles, so room temperature is more constant. A larger swing number

decreases the number of cycles, to save energy in most cases.

• Reprogram as necessary.

SMART RECOVERY

Your thermostat has the capability to turn the HEAT and AIR CONDITIONING

ON in your home so that it reaches your desired comfort temperature at the

time you have programmed. For instance, if you have programmed your

thermostat for 70° at 5:00pm, normally the thermostat will begin to heat your

home at 5:00pm. With SMART RECOVERY on, the thermostat will calculate the

best time to turn the heat on so that the temperature in your home reaches 70°

by 5:00pm. It calculates the amount of time through experience and will get

more accurate as time goes by. To enable SMART RECOVERY, remove J3 on

the back of the thermostat. Press the small reset button on the front of the

thermostat. IN RECOVERY will appear in the display when this feature is

bringing your home to temperature.
