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.

All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting compo-
nents could cause the control to malfunction.
To prevent electrical shock and/or equipment
damage, disconnect electric power to system, at
main fuse or circuit breaker box, until installation
is complete.
Do not use on circuits exceeding specified volt-
age. Higher voltage will damage control and
could cause shock or fire hazard.
Do not short out terminals on gas valve or pri-
mary control to test. Short or incorrect wiring will
burn out thermostat and could cause personal
injury and/or property damage.
