FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
This wall-mounted, low voltage thermostat maintains
room temperature by controlling the operation of heating
and cooling systems. The user may program up to four
time/temperature settings per 24 hour period. The ther-
mostat stores independent heating and cooling programs
for 5-day (weekday) and 2-day (weekend) periods. The
thermostat will store both heating and cooling programs
simultaneously. Three “AA” Energizer® batteries will main-
tain the stored program for approximately one year, if
incoming power should fail. If power failure is extensive
and the program is lost, after power restoration, the
thermostat will automatically maintain a factory
preprogrammed heating temperature of 64
°F or a cooling
temperature of 82
°F.

Troubleshooting
Do not exceed the specification ratings.
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 the control and
could cause shock or fire hazard.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will burn
out thermostat and could cause personal injury
and/or property damage.
