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 voltage.
Higher voltage will damage 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 damage
thermostat and could cause personal injury and/or
property damage.
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION

®
alkaline batteries in-
cluded).
• Separate 5-day (weekday) and 2-day (weekend) programming
• Simultaneous heat and cool program storage
• Preprogrammed temperature control
• Four separate time/temperature settings per 24-hour period
• LCD continuously displays set point, and alternately dis-
plays time and room temperature
• Temperature override until next program period
• Manual program override (HOLD temperature)
• User may select either 12- or 24-hour clock display
