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.
