This thermostat is intended for use with a low voltage NEC 
Class II 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 qualifi ed heating and air 
conditioning contractor or electrician.

Do not exceed the specifi cation 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.
