INSTALLATION AND

OPERATION INSTRUCTIONS

PRECAUTIONS

CAUTION

This thermostat is intended for use with a low voltage system; do

not use this thermostat with a line voltage system. If in doubt

about whether your wiring is millivolt, line, or low voltage, have

it inspected by a qualified heating and air conditioning contractor

or electrician.

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 components could cause

the control to malfunction.

To prevent electrical shock and/or equipment dam-

age, disconnect electric power to system at main fuse

or circuit breaker box until installation is complete.

WARNING

Operator: Save these instructions for future use!
