PRECAUTIONS

Operator: Save these instructions for future use!

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 famil-
iar with basic electricity and wiring.

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.

CAUTION

To prevent electrical shock and/or equipment
damage, disconnect electric power to system, at
main fuse or circuit breaker box, until installa-
tion is complete.

Do not use on circuits exceeding specified volt-
age. Higher voltage will damage control - could
cause shock or fire hazard.
