To change your clock, follow the instruc- tions for setting current time and day. See ENTERING YOUR PROGRAM. Thermo- stat programming is not affected when you change the clock.

16.Do I have to reprogram my thermostat after I change the batteries?

When the thermostat is on the wall and the system has power, the thermostat is being powered by a 24 VAC source. If power is lost, or if the thermostat is removed from the wall, the program will be retained for ap- proximately one minute if there are no batteries installed or if the installed batteries are dead. If you are changing the batteries

after seeing a flashing BATTERY on the display, the installed batteries may be dead.

If you remove the old batteries and install fresh ones within one minute, you should not lose your thermostat programming. Af- ter installing new batteries, follow the proce- dures in CHECK YOUR PROGRAMMING to determine whether your programming was maintained. If the thermostat maintains

programming, press SYSTEM until OFF is
