PRECAUTIONS
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.
