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 systems 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.
