FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.

nient control of the heating/cooling system. To provide
greater room comfort, the sensitive spiral bimetal is com-
bined with an adjustable heating anticipator and a fixed
cooling anticipator to provide maximum comfort.
If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
Do not exceed the specification ratings.

INSTALLATION INSTRUCTIONS
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 short out terminals on gas valve or pri-
mary control to test. Short or incorrect wiring will
burn out heat anticipator and could cause per-
sonal injury and/or property damage.
Do not use on circuits exceeding 30 volts. Higher
voltage will damage control and could cause
shock or fire hazard.
