18.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 24v AC source. If power is lost, or if the thermostat is removed from the wall, the program will be retained for approximately 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 batter- ies may be dead. If you remove the old

batteries and install fresh ones within one minute, you should not lose your thermostat programming. After installing new batteries, follow the procedures in CHECK YOUR PRO- GRAMMING to determine whether your pro- gramming was maintained. If the thermostat

maintains programming, press	SYSTEM	until
	SWITCH

OFF is displayed, put the thermostat back on

the wall, press	SYSTEM	to select the operat-
	SWITCH

ing mode you want, then press PRGMRUN to start

program operation. If the program is lost, reprogram the thermostat. See PROGRAM-

MING YOUR THERMOSTAT.
