White Rodgers 1F94-71 - Manual

Printed in U.S.A.
This wall-mounted, low voltage thermostat maintains
room temperature by controlling the operation of multi-
stage systems. Use this thermostat for applications
requiring up to three stages of heat and up to two stages
of cool. Indicator lights show the system status. The user
may program up to four time/temperature settings per 24
hour period. The thermostat stores programs for seven
independent days. The thermostat will store both heating
and cooling programs simultaneously. A 9 volt Energizer
®
battery will maintain the stored program for approximately
one week, if incoming power should fail. If power failure
is extensive and the program is lost, after power restora-
tion, the thermostat will automatically maintain a factory
preprogrammed heating temperature of 64
°
F or a cooling
temperature of 82
°
F.
